what is equation?

A mathematical assertion that demonstrates the equality of two expressions is called an equation The equals symbol (=) is used to denote the separation of two phrases. Numerous mathematical ideas and relationships, including linear functions, quadratic functions, and trigonometric functions, can be represented by equations.

Let's use the letter 'h' to indicate how many hours the plumber put in.

The plumber costs $35 to come to Jerald's residence and $50 for every hour they work. If Jerald is charged a total of $190 by the plumber, the following equation can be written:

$50h + $35 = $190

To solve for 'h,' we obtain:

$50h = $190 - $35

$50h = $155

h = 155 / 50

h = 3.1

Consequently, the plumber put in 3.1 hours of work (or 3 hours, 6 minutes).

a group of marketing students at a large university wants to determine the proportion of first year students who use certain types of social media. the students want their estimate to be within 0.03 of the true proportion with a 90% level of confidence. how large of a sample is required if the population proportion is not known?

Answers

The required sample size is  8.90400.

Given a student wants to make a guess within 0.03 of the true ratio with a 90% confidence level.

Margin of Error, E = 0.03

significance level α=0.10  {90% confidence}

A given estimate of the percentage of population p is p = 0.79.

The critical value for the significance level α = 0.10 is Zc = 1.645. This can be determined using either Excel or a normal probability table.

Use the following formula to calculate the minimum sample size required to estimate the percentage of population p within the required margin of error.

n≥p(1-p)(Zc÷E)²

n = 0.796×(1-0.796)(1.645÷0.03)²

n = 0.796 x 0.204 x 54.833

n = 8.90400

Therefore, the resample size required to meet the condition is n ≥  8.90400 and must be an integer. From this, we conclude that the minimum sample size required is n =  8.90400

Answers

The value of the digit 5 in 24,513 is 1,000 times the value of the digit 5 in 357.

In the number 357, the digit 5 is in the ones area, which means that its value is just 5. We can write this number as 5 x 10^0, where 10 is the base of our number system, and the exponent 0 represents the ones area.

Now, to find out how many times the value of the digit 5 in 357 is compared to the value of the digit 5 in 24,513, we need to divide the value of the digit 5 in 24,513 by the value of the digit 5 in 357.

We have:

Value of 5 in 24,513 = 5 x 10³

Value of 5 in 357 = 5 x 10⁰

So,

Value of 5 in 24,513 ÷ Value of 5 in 357 = (5 x 10³) ÷ (5 x 10⁰)

We can simplify this expression by dividing 5 by 5, which gives us:

(5 x 10³) ÷ (5 x 10⁰) = 10³ = 1000

what is statistics?

Statistics is a branch of mathematics that deals with collecting, analyzing, interpreting, presenting, and organizing data. It involves the study of methods for designing experiments and surveys, analyzing and interpreting data, and making decisions based on data. Statistics plays an important role in a wide range of fields, including science, social science, economics, finance, engineering, and many others. It is used to draw conclusions, make predictions, and inform decision-making by providing a quantitative and objective approach to understanding and analyzing data.

The most accurate measure of variability to use for this data set is the range of 49. The range is the difference between the highest and lowest values in the data set, which in this case is 59 - 10 = 49. The range provides a simple and straightforward measure of the spread of the data and is useful when the data is not too skewed.

While the data in this set is skewed, the range is still an appropriate measure of variability because there are no extreme outliers that would significantly affect the range. The IQR (interquartile range) is another measure of variability that is useful for skewed data, but in this case, it would not be the most appropriate choice because the data set is not divided into quartiles and the IQR would not provide additional information beyond what the range already shows.

Therefore, the range of 49 is the most appropriate measure of variability to use to represent the spread of donations received by the charity in this data set.

An animal population N(t) is modeled by the differential equation:
dN/dt = -0. 001N(N - 110)(N - 99). If N(0)=A, where A is a positive integer, what is the maximum value of the positive integer A such that extinction will occur?

Answers

For the given integer, the maximum starting population size that will eventually lead to extinction is 98, since any larger value will result in the population either stabilizing at a positive value or growing indefinitely.

The equation in question is:

dN/dt = -0.001N(N - 110)(N - 99)

Here, N represents the population size, and dN/dt represents the rate of change of the population with respect to time. The right-hand side of the equation tells us how the population size changes over time, and it's determined by the current population size N, as well as the two constants 110 and 99.

We can do this by setting dN/dt equal to zero and solving for N:

dN/dt = -0.001N(N - 110)(N - 99) = 0

=> N = 0, N = 99, N = 110

We can then plot the direction field (i.e., arrows indicating the direction of change) on each interval, and use this to determine the behavior of the solution curve. In this case, we can see that the direction of the arrows changes at each critical point, indicating that the population behavior switches between growing and declining as we move from one interval to the next.

Specifically, we can see that if the initial population size A is less than 99, the population will decline to extinction. If the initial population size is between 99 and 110, the population will initially decline but then grow and eventually stabilize at N = 110. If the initial population size is greater than 110, the population will grow exponentially and tend towards infinity.

Part C: What is the average rate of change of the function f(d) from d = 4 to d = 11, and what does it represent? (4 points)

Answers

Part A: A reasonable domain to plot the growth function would be from d = 0 to d = 11.

Part B: The y-intercept of the graph of the function f(d) is 7

Part C: The average rate of change of the function f(d) from d = 4 to d = 11 is approximately 0.64 mm/day.

Domine and y-intercept of a function:

The domain of a function represents the set of input values for which the function is defined and can produce a meaningful output.

The y-intercept of a function represents the value of the function when the input is equal to zero.

The average rate of change of a function from x = a to x = b is given by the slope of the secant line passing through the points (a, f(a)) and (b, f(b)).

Here we have

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:

=> f(d) = 7(1.06)^d

Since it is given that the radius of the algae was approximately 13.29 mm when the biologist concluded her study, we can set f(d) = 13.29  

=> 13.29 = [tex]7(1.06)^{d}[/tex]

=> ln(13.29/7) = d ln(1.06)

=> d = ln(13.29/7)/ln(1.06) ≈ 11  

Therefore, A reasonable domain to plot the growth function would be from d = 0 to d = 11.

Part B: The y-intercept of the graph of the function f(d) represents the value of the function when d = 0.

Substituting d = 0 into the given equation, we get:

f(0) = 7(1.06)⁰ = 7

Therefore, The y-intercept of the graph of the function f(d) is 7

Part C: The average rate of change of the function f(d) from d = 4 to d = 11 is given by the slope of the secant line passing through the points (4, f(4)) and (11, f(11)). Using the given equation, we can evaluate f(4) and f(11):

f(4) = 7(1.06)⁴ ≈ 8.84

f(11) = 7(1.06)¹¹ ≈ 13.29

The slope of the second line passing through these two points is:

Slope = (f(11) - f(4))/(11 - 4) = [ 13.29 - 8.84]/7 = 0.64

Therefore,

The average rate of change of the function f(d) from d = 4 to d = 11 is approximately 0.64 mm/day.

Solve this proportion 12/m = 18/9

Answers

Answer:

m = 6

Step-by-step explanation:

We have the proportion:

12/m = 18/9

To solve for m, we can cross-multiply the terms in the proportion:

12 × 9 = 18 × m

Simplifying both sides of the equation, we get:

108 = 18m

Dividing both sides by 18, we get:m = 6

Therefore, the solution to the proportion 12/m = 18/9 is m = 6.

Answer: m = 6

Step-by-step explanation:

First, we will rewrite this proportion:

     [tex]\displaystyle \frac{12}{m} =\frac{18}{9}[/tex]

Next, we will cross-multiply:

     12 * 9 = 18 * m

     108 = 18m

Lastly, we will divide both sides of the equation by 18:

     m = 6

We can also solve this proportion another way.

     We know that 18/9 = 2, so 12/m must equal 2 as well.

     12/6 = 2, so m = 6.

Find two algebraic expressions for the area of each figure. First, regard the figure as one large rectangle, and then regard the figure as a sum of four smaller rectangles

Answers

According to the algebraic expressions, the sum of four smaller rectangles is 96.

First, let's consider the figure as one large rectangle. To find the area of a rectangle, we multiply its length by its width. In this case, the length of the rectangle is 8 and the width is 6 + 2 + 4 = 12. Therefore, the expression for the area of the rectangle can be written as:

Area = length x width

Area = 8 x 12

Area = 96

So the area of the figure as one large rectangle is 96 square units.

To find the area of each rectangle, we'll use the formula for the area of a rectangle, which is length x width. We can see from the figure that:

Rectangle A has a length of 8 and a width of 6

Rectangle B has a length of 8 and a width of 2

Rectangle C has a length of 4 and a width of 6

Rectangle D has a length of 4 and a width of 2

Therefore, the expressions for the area of each rectangle can be written as:

Area_A = length x width

Area_A = 8 x 6

Area_A = 48

Area_B = length x width

Area_B = 8 x 2

Area_B = 16

Area_C = length x width

Area_C = 4 x 6

Area_C = 24

Area_D = length x width

Area_D = 4 x 2

Area_D = 8

To find the total area of the figure, we simply add up the areas of the four rectangles. Therefore, the expression for the area of the figure as a sum of four smaller rectangles can be written as:

Area = Area_A + Area_B + Area_C + Area_D

Area = 48 + 16 + 24 + 8

Area = 96

pyriamid a square base that measures 140 m on each side. the height is 91 m. what is the volume of the pyramid?

Answers

The volume of the pyramid is approximately 574,533.33 cubic meters.

To find the volume of a pyramid, you use the formula: V = (1/3) × base area × height, where B is the area of the base and h is the height of the pyramid.

Given that the side length of the square base is 140 m and the height is 91 m.

Since the base of the pyramid is a square with a side length of 140 m, we can find its area by multiplying the side lengths: B = 140m x 140m = 19,600 square meters.
By calculating this expression, you'll find the volume of the pyramid.

Now we can plug in the values for B and h into the formula: V = (1/3)(19,600 square meters)(91 meters) = 574,533.33 cubic meters.

in a(n) , the scale questions are divided into two parts equally and the resulting scores of both parts are correlated against one another.

Answers

The main topic is the split-half reliability test used in psychological research to assess the internal consistency of a scale.

How to test the  psychological research?

In psychological research, reliability is a crucial aspect of measuring constructs or attributes. One commonly used method for assessing the reliability of a scale is the split-half reliability test.

In this test, the scale questions are divided into two parts equally, and the resulting scores of both parts are correlated against one another.

For example, if a scale had 20 items, the items could be randomly split into two groups of 10 items each.

Scores are then calculated for each group, and the scores are correlated with each other to determine the degree of consistency between the two halves.

The correlation coefficient obtained from this analysis provides an estimate of the internal consistency of the scale.

A high correlation coefficient indicates a high level of internal consistency, indicating that the two halves of the scale are measuring the same construct or attribute.

Conversely, a low correlation coefficient suggests that the two halves of the scale are not measuring the same construct or attribute, and the scale may need to be revised or abandoned.

Overall, the split-half reliability test provides a quick and efficient method for evaluating the reliability of a scale.

However, it is important to note that this method does have some limitations, such as the possibility of unequal difficulty or discrimination of the items in each half of the scale.

Therefore, researchers often use other methods, such as Cronbach's alpha, in conjunction with the split-half reliability test to provide a more comprehensive assessment of the reliability of a scale

What is the surface area of the actual ramp, including the underside? Enter your answer as a decimal in the box. yd² Right triangular prism. Each base is a triangle whose legs are 8 in, 5 in, and 5 in. The height of the triangles is 3 in. The prism is oriented so that the side labeled 8 in is on the bottom. The distance between the bases is labeled 4 in.

Answers

The surface area of the actual ramp, including the underside, is approximately 15.38 yd².

What is triangle?

A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.

To find the surface area of the actual ramp, we need to first find the dimensions of the ramp.

We are given that the scale model of the ramp is a right triangular prism with legs of 8 in, 5 in, and 5 in, and a height of 3 in. We can use these dimensions to find the dimensions of the actual ramp.

Since the ramp is a scale model, the ratio of the dimensions of the model to the actual ramp is the same for all corresponding dimensions. The height of the triangular base in the actual ramp is given as 0.6 yards, which is equal to 21.6 inches. So, we have:

height of actual ramp / height of model = 21.6 in / 3 in = 7.2

We can use this ratio to find the dimensions of the actual ramp:

height of actual ramp = 7.2 * 3 in = 21.6 in

length of actual ramp = 7.2 * 8 in = 57.6 in

width of actual ramp = 7.2 * 5 in = 36 in

Now we can find the surface area of the actual ramp. The surface area of the top and bottom of the ramp is the area of the triangular base plus the area of the rectangle formed by the length and width of the ramp:

Area of triangular base = (1/2) * base * height = (1/2) * 5 in * 5 in = 12.5 in²

Area of rectangular top and bottom = length * width = 57.6 in * 36 in = 2073.6 in²

Total surface area of top and bottom = 2 * (Area of triangular base + Area of rectangular top and bottom) = 2 * (12.5 in² + 2073.6 in²) = 4153.2 in²

The surface area of the sides of the ramp is the area of the three rectangles formed by the height and width of the ramp:

Area of one side rectangle = height * width = 21.6 in * 36 in = 777.6 in²

Total surface area of sides = 3 * Area of one side rectangle = 3 * 777.6 in² = 2332.8 in²

Finally, we add the surface area of the top and bottom to the surface area of the sides to get the total surface area of the ramp:

Total surface area of ramp = Surface area of top and bottom + Surface area of sides = 4153.2 in² + 2332.8 in² = 6486 in²

Converting to yards and rounding to two decimal places, we get:

Total surface area of ramp = 6486 in² / (36 in/yd)² = 15.38 yd² (rounded to two decimal places)

Therefore, the surface area of the actual ramp, including the underside, is approximately 15.38 yd².

Jackie has $500 in a savings account.The interest rate is 5% per year and is not compounded. How much will she have in total in 1 year?

Answers

Answer:

$525

Step-by-step explanation:

Jackie starts with $500, and the interest rate is 5% per year.

This means that, after one year, Jackie will have accumulated 5% interest with the $500 she put into the savings account.

Now, we can find 5% of $500 by converting 5% to its fraction form, which is 5/100. 5% of a value means that you need to multiply the fraction (or decimal) by the said value. So, we have:

[tex]\frac{5}{100}[/tex] · 500 =

[tex]\frac{2500}{100}[/tex] =

25

Therefore, the amount of interest she has accumulated in one year is $25. Combined with the money in her savings account, she has $525, since $500 + $25 = $525.

deigo has budgeted $35 from his summer job earnings to buy shorts and socks for soccer. He neefs 5 pairs of socks and a pair of shorts. The socks cost different amounts in different stories. The shorts he wants cost $19.95. list some other possible prices for the socks that would still allow diego to stay with in his budget​

Answers

Some possible prices for the socks that would meet this condition are $2.99, $2.50, $3.00, $2.95, etc.

Define rate

A rate is a measure of the amount of change of one quantity with respect to another quantity. It expresses how much one quantity changes in relation to another quantity over a given time or distance.

If Diego has budgeted $35 for 5 pairs of socks and a pair of shorts, we can subtract the cost of the shorts from the total budget to find the amount he has left for the socks:

$35 - $19.95 = $15.05

To find the possible prices for the socks, we can divide the amount Diego has left by the number of pairs of socks he needs:

$15.05 / 5 pairs = $3.01 per pair

Therefore, Diego would be able to stay within his budget if he finds socks that cost $3.01 or less per pair. Some possible prices for the socks that would meet this condition are $2.99, $2.50, $3.00, $2.95, etc.

Find the missing measure.

Answers

The missing angles in the given pair of lines AB and CD with transversals EF & GH intersecting at O & missing sides on the basis of similarity of triangles are:

∠IKF=w°=109°

JO=z=2.7 units

∠JLO=x°=39°

∠DLO=y°=141°

What is similarity?

If two forms or figures have an equal number of comparable sides and angles, they are said to be similar. Similar figures are those when two or more figures share the same shape but have varied sizes.

Given that

∠KIO=39°

∠IKO=71°

∠IOK=70°

IO=12 units

KO=8 units

LO=4 units

a)We know that ∠KIO=∠OLJ  {alternate interior angles}

∠KIO=∠OLJ=39°

∴x° = 39°

b)We know that ∠OLJ+∠OLD=180° {linear pair}

x°+y°=180°

39°+y°=180°

y°=180-39

y°=141°

c)We know that ∠IKO+∠IKF=180° {angles on straight line}

71°+w°=180°

w°=180-71

w°=109°

d)In ΔOKI and ΔOJL, we can see that

∠OIK=∠OLJ=39°

∠OKI=∠OJL=71°

∠KOI=∠JOL=70°

as the angles are congruent, we can say that ΔOKI and ΔOJL are similar.

∴Sides will be in same ratio

[tex]\frac{OI}{OL}[/tex]  = [tex]\frac{OK}{OJ}[/tex]  = [tex]\frac{KI}{JL}[/tex]

Taking [tex]\frac{OI}{OL}[/tex]  = [tex]\frac{OK}{OJ}[/tex]

[tex]\frac{12}{4} = \frac{8}{z}[/tex]

Mia removes the plug from a trough to drain the water. The volume, in gallons, in the trough after it has been unplugged can be modeled by f(x) = 10x2 −19x + 6, where x is time in minutes. Which of the following equations will reveal the time in minutes when the trough is empty?

Answers

Therefore, the time in minutes when the trough is empty is approximately 0.313 minutes.

To find the time in minutes when the trough is empty, we need to solve the equation f(x) = 0, since f(x) represents the volume of water in the trough.

So, we need to solve the quadratic equation:

[tex]10x^2 - 19x + 6 = 0[/tex]

To solve this equation, we can use the quadratic formula:

[tex]x = (-b ± \sqrt(b^2 - 4ac)) / 2a[/tex]

where a = 10, b = -19, and c = 6.

Plugging in these values, we get:

[tex]x = (-(-19) ± \sqrt((-19)^2 - 4(10)(6))) / 2(10)[/tex]

[tex]x = (19 ± sqrt(241)) / 20[/tex]

So, the two solutions are:

[tex]x = (19 + \sqrt(241)) / 20 \approx1.807 minutes[/tex]

[tex]x = (19 - \sqrt(241)) / 20 \approx0.313 minutes[/tex]

However, only the second solution makes sense in this context, since the trough cannot be empty before we start draining the water. Therefore, the time in minutes when the trough is empty is approximately 0.313 minutes.

What is evaluation in education?

Assessment is an ongoing process of gathering evidence of what each student actually knows, understands, and can do. A comprehensive evaluation approach includes a combination of formal and informal evaluation (formative, preliminary, and summative).

What is an assessment? Also what does it mean?

At the course level, assessments provide important data on the breadth and depth of student learning. Evaluation is more than scoring. It's about measuring student learning progress.

Answers

In the given problem, the surface area of the triangular prism is 65 square centimeters. The answer is not listed among the options provided

To to Calculate Surface Area?

We need to find the surface area of the triangular prism, which is the sum of the areas of all its faces.

The triangular faces of the prism are congruent triangles, so we can find their area by multiplying the base and height and dividing by 2. The dimensions of the triangular faces are 5 cm (base) and 4 cm (height).

Area of each triangular face = (5 cm x 4 cm)/2 = 10 cm²

The rectangular faces are congruent rectangles, so we can find their area by multiplying the length and width. The dimensions of the rectangular faces are 5 cm x 3 cm and 3 cm x 4 cm.

Area of each rectangular face = (5 cm x 3 cm) = 15 cm²

Total surface area of the prism = 2 x Area of triangular face + 3 x Area of rectangular face

= 2 x 10 cm² + 3 x 15 cm²

= 20 cm² + 45 cm²

= 65 cm²

Therefore, the surface area of the triangular prism is 65 square centimeters. The answer is not listed among the options provided, so there might be a mistake in the question or answer choices.

the value of the action potential -- how much greater the electric potential is inside the axon as compared to outside the axon -- is around 30 mv for the average neuron in humans. if the length constant of an axon is about 2 mm, at what distance (to the nearest tenth of a mm) from the end of the axon where this action potential is applied would the potential difference across the membrane become less than 3.3 mv (which is a very weak signal)? (and this fast decay of the potential difference is why the action potential must be regenerated with further depolarization along the axon. with additional depolarization down the length of the axon, the action potential is thus maintained as a strong voltage pulse -- again, with a maximum value of around 30 mv -- that can travel along the entire length of axons, which can be over a meter long!) again, we can use the equation that relates the potential difference across a membrane as a function of how far from the end of the axon this potential difference is measured, i.e., .
