The Johnson family lives 432 miles from the beach. They drive 52% of the distance before stopping for lunch. About how many miles do they drive before lunch? Explain how you can use mental math to find the answer.​

Answers

Answer 1
To find the distance the Johnson family drives before stopping for lunch, we can multiply the total distance to the beach by the percentage of the distance they drive before stopping for lunch.

52% of 432 miles can be found by multiplying 0.52 by 432:

0.52 * 432 = 224.64 miles

To use mental math to find the answer, we can round 432 to 400, which makes the calculation easier.

52% of 400 can be found by multiplying 0.5 by 400 and adding 2% of 400:

0.5 * 400 + 0.02 * 400 = 200 + 8 = 208 miles

Then, we can adjust for the fact that we rounded 432 to 400 by adding 32/400, which is 0.08, to the result:

208 + 0.08 * 432 = 208 + 34.56 = 242.56 miles

Therefore, the Johnson family drives about 242.56 miles before stopping for lunch.

What is an algebraic expression?

An algebraic expression is a mathematical phrase that contains variables, constants, and mathematical operations. It may also include exponents and/or roots. Algebraic expressions are used to represent quantities and relationships between quantities in mathematical situations, often in the context of problem-solving.

To find the cost of 1 cupcake, we need to subtract the cost of the tea from the total cost of 3 cupcakes:

3 cupcakes + 1 tea = £9

3 cupcakes = £9 - 1 tea = £9 - £1.5 (assuming the cost of 1 tea is the same in both cases) = £7.5

1 cupcake = £7.5 ÷ 3 = £2.5

So 2 cupcakes would cost:

2 cupcakes = 2 × £2.5 = £5

Therefore, the answers are:

a) 2 cakes cost £5

b) 1 cake costs £2.5.

the rule T(-3,1) is applied to point 2,-7 in which part of the coordinate system is the translated point

Answers

the translated point is located in the third quadrant of the coordinate system, since both coordinates are negative.

What is Cartesian coordinate?

A coordinate system, also known as a Cartesian coordinate system, is a system used to describe the position of points in space. It is named after the French mathematician and philosopher René Descartes, who introduced the concept in the 17th century. In a coordinate system, each point is assigned a unique pair of numbers, called coordinates, that describe its position relative to two perpendicular lines, called axes. The horizontal axis is usually labeled x and the vertical axis is usually labeled y.

To apply the translation rule T(-3, 1) to the point (2, -7), we need to add the translation vector (-3, 1) to the coordinates of the point:

(2, -7) + (-3, 1) = (-1, -6)

The resulting point after the translation is (-1, -6).

Therefore, the translated point is located in the third quadrant of the coordinate system, since both coordinates are negative.

Find the avatar rate of change f(x)=3√x-1 +2; 9 ≤ x ≤ 65

Answers

Answer: To find the average rate of change of the function f(x) over the interval [9, 65], we can use the formula:

average rate of change = (f(b) - f(a)) / (b - a)

where a = 9, b = 65, f(a) = f(9) = 3√8 + 2, and f(b) = f(65) = 3√64 + 2.

what is the maximum number of consecutive odd positive integers that can be added together before the sum exceeds ?

Answers

The maximum number of consecutive odd positive integers that can be added together before the sum exceeds 401 is 11.

Let's assume the first odd integer is x. Then, the sum of the next n consecutive odd integers would be given by:

x + (x+2) + (x+4) + ... + (x+2n-2) = nx + 2(1+2+...+n-1) = nx + n(n-1)

We want to find the largest n such that the sum is less than or equal to 401:

nx + n(n-1) ≤ 401

Since the integers are positive and odd, we can start with x=1 and then try increasing values of n until we find the largest value that satisfies the inequality:

n + n(n-1) ≤ 401

n² - n - 401 ≤ 0

Using the quadratic formula, we find that the solutions are:

n = (1 ± √(1+1604))/2

n ≈ -31.77 or n ≈ 32.77

We discard the negative solution and round down to the nearest integer, giving us n = 11. Therefore, the maximum number of consecutive odd positive integers that can be added together before the sum exceeds 401 is 11.

Answers

Standard deviation normal distribution table or calculator to determine the probability of observing a z-score of 1.3 or higher.

The probability is approximately 0.0968, or 9.68%.

To determine the mean number of times the letter appears on a page, we can multiply the probability of the letter appearing (0.066) by the total number of characters on the page (2650):

[tex]Mean = 0.066 \times 2650 = 174.9[/tex]

To calculate the standard deviation, we can use the formula:

Standard deviation = [tex]\sqrt(n \times p \times q)[/tex]

n is the sample size (2650), p is the probability of success (0.066), and q is the probability of failure [tex](1 - p = 0.934)[/tex].

Standard deviation = [tex]sqrt(2650 \times 0.066 \times 0.934) = 13.2[/tex] (rounded to 1 decimal place)

Determine whether 192 occurrences of the letter on a page is unusual, we can use the z-score formula:

z = (x - mean) / standard deviation

x is the observed number of occurrences (192), mean is the expected number of occurrences (174.9), and standard deviation is the standard deviation we just calculated (13.2).

three bolts and three nuts are in a box. two parts are chosen at random. find the probability that one is a bolt and one is a nut.

Answers

The probability of picking one bolt and one nut is 1/2 or 50%.

To find the probability that one is a bolt and one is a nut, we need to use the formula for calculating the probability of two independent events happening together: P(A and B) = P(A) × P(B)

Let's first calculate the probability of picking a bolt from the box:

P(bolt) = number of bolts / total number of parts = 3/6 = 1/2

Now, let's calculate the probability of picking a nut from the box:

P(nut) = number of nuts / total number of parts = 3/6 = 1/2

Since the events are independent, the probability of picking a bolt and a nut in any order is:

P(bolt and nut) = P(bolt) × P(nut) + P(nut) × P(bolt)

P(bolt and nut) = (1/2) × (1/2) + (1/2) × (1/2)

P(bolt and nut) = 1/2

the probability that one chosen part is a bolt and the other chosen part is a nut is 1, or 100%. This makes sense because if we choose two parts at random, we must get one bolt and one nut since there are three of each in the box.

To find the probability that one chosen part is a bolt and the other chosen part is a nut, we need to use the formula for probability:

Probability = (number of desired outcomes) / (total number of outcomes)

There are two ways we could choose one bolt and one nut: we could choose a bolt first and a nut second, or we could choose a nut first and a bolt second. Each of these choices corresponds to one desired outcome.

To find the number of ways to choose a bolt first and a nut second, we multiply the number of bolts (3) by the number of nuts (3), since there are 3 possible bolts and 3 possible nuts to choose from. This gives us 3 x 3 = 9 total outcomes.

Similarly, there are 3 x 3 = 9 total outcomes if we choose a nut first and a bolt second.

Therefore, the total number of desired outcomes is 9 + 9 = 18.

The total number of possible outcomes is the number of ways we could choose two parts from the box, which is the number of ways to choose 2 items from a set of 6 items. This is given by the formula:

Total outcomes = (6 choose 2) = (6! / (2! * 4!)) = 15

Putting it all together, we have:

Probability = (number of desired outcomes) / (total number of outcomes)
Probability = 18 / 15
Probability = 1.2

However, this answer doesn't make sense because probabilities should always be between 0 and 1. So we made a mistake somewhere. The mistake is that we double-counted some outcomes. For example, if we choose a bolt first and a nut second, this is the same as choosing a nut first and a bolt second, so we shouldn't count it twice.

To correct for this, we need to subtract the number of outcomes we double-counted. There are 3 outcomes that we double-counted: choosing two bolts, choosing two nuts, and choosing the same part twice (e.g. choosing the same bolt twice). So we need to subtract 3 from the total number of desired outcomes:

Number of desired outcomes = 18 - 3 = 15

Now we can calculate the correct probability:

Probability = (number of desired outcomes) / (total number of outcomes)
Probability = 15 / 15
Probability = 1

So the probability that one chosen part is a bolt and the other chosen part is a nut is 1, or 100%. This makes sense because if we choose two parts at random, we must get one bolt and one nut since there are three of each in the box.

assume that arrivals occur according to a poisson process with an average of seven per hour. what is the probability that exactly two customers arrive in the two-hour period of time between a 2:00 p.m. and 4:00 p.m. (one continuous two-hour period)? b 1:00 p.m. and 2:00 p.m. or between 3:00 p.m. and 4:00 p.m. (two separate one-hour periods that total two hours)?

Answers

a) The probability that exactly two customers arrive between 2:00 p.m. and 4:00 p.m. is 0.0915 (or approximately 9.15%).

b) The probability of at least one customer arriving between 1:00 p.m. and 2:00 p.m. or between 3:00 p.m. and 4:00 p.m. is approximately 0.99999917.

For a Poisson process, the number of arrivals in a fixed time interval follows a Poisson distribution.

Let's denote the number of arrivals in a two-hour period as X.

Since the average number of arrivals per hour is 7, the average number of arrivals in a two-hour period is 14.

Therefore, we have λ = 14.

a) Probability of exactly 2 customers arriving between 2:00 p.m. and 4:00 p.m.:

Using the Poisson distribution formula, the probability of X arrivals in a two-hour period is:

[tex]P(X = x) = (e^{-\lambda} * \lambda^x) / x![/tex]

So, for X = 2, we have:

[tex]P(X = 2) = (e^{-14} * 14^2) / 2! = 0.0915[/tex] (rounded to four decimal places)

Therefore, the probability that exactly two customers arrive between 2:00 p.m. and 4:00 p.m. is 0.0915 (or approximately 9.15%).

b) Probability of at least one customer arriving between 1:00 p.m. and 2:00 p.m. or between 3:00 p.m. and 4:00 p.m.:

We can approach this problem by using the complementary probability. The complementary probability of at least one customer arriving in a two-hour period is the probability of no customers arriving in that period. Since the arrival rate is the same for each hour, we can divide the two-hour period into two one-hour periods and use the Poisson distribution formula for each period separately.

The probability of no customers arriving in a one-hour period with λ = 7 is:

[tex]P(X = 0) = (e^{-7}* 7^0) / 0! = 0.000911[/tex]

The probability of no customers arriving in a two-hour period is the product of the probabilities for each one-hour period:

P(no customers in two-hour period) = P(X = 0) * P(X = 0) = 0.000911 * 0.000911 = 8.30e-7

The complementary probability of at least one customer arriving in a two-hour period is:

P(at least one customer in two-hour period) = 1 - P(no customers in two-hour period) = 1 - 8.30e-7 = 0.99999917 (rounded to eight decimal places).

Based on your construction, what do you know about ΔABD and ΔBCD?

Answers

The construction and the resulting triangles are interesting because they allow us to explore the properties of perpendicular lines and the angles they form.

Now, let's look at the two triangles that are formed as a result of this construction - ΔABD and ΔBCD. Since line BD is perpendicular to line AC, we know that angle ABD and angle CBD are both right angles. This is because any line that is perpendicular to another line forms a right angle with that line.

Now, let's look at the other sides of the triangles. In ΔABD, we have side AB, which is different from side BC in ΔBCD. Similarly, in ΔBCD, we have side CD, which is different from side AD in ΔABD.

So, although the two triangles share a common side (BD), they have different lengths for their other sides. This means that the two triangles are not congruent, since congruent triangles must have the same length for all their sides.

However, we can still find some similarities between the two triangles. For example, since angle ABD and angle CBD are both right angles, we know that they are congruent. Additionally, we can use the fact that angle ADB is congruent to angle CDB, since they are alternate interior angles formed by a transversal (line BD) intersecting two parallel lines (line AC and the line perpendicular to it passing through point B).

There are 0.75 pounds of food in each can of dog food. We must divide 2.25 by 0.75 to find the quantity of dog food Shawna should leave for her companion. 3 dog food cans are the end outcome.Shawna ought to give her buddy three cans of dog food so that she can feed her dogs.

Shawna may make sure her dogs have enough food and are well cared for while she is away by leaving adequate food for them. Shawna may put any fears or concerns about her pets' welfare to rest by leaving ample food and clear directions.

Find the exact value of sin a, given that cos a=-5/9 and a is in quadrant 3

Answers

Since cosine is negative and a is in quadrant III, we know that sine is positive. We can use the Pythagorean identity to solve for sine:

sin^2(a) + cos^2(a) = 1

sin^2(a) + (-5/9)^2 = 1

sin^2(a) = 1 - (-5/9)^2

sin^2(a) = 1 - 25/81

sin^2(a) = 56/81

Taking the square root of both sides:

sin(a) = ±sqrt(56/81)

Since a is in quadrant III, sin(a) is positive. Therefore:

sin(a) = sqrt(56/81) = (2/3)sqrt(14)

B. 221(2.35) + 362(2.35)

C. 221(1.75) + 362(1.75)

D. 362(1.75) + 221(2.35)

Answers

Answer:

The answer is D.

Explanation:

There were 362 cans of soft drinks sold for $1.75 each so you would multiply them together to get the sales of soft drinks. There were also 221 hot dogs for $2.35 each so you would multiply them together to get the sales of hot dogs. Since the problem is asking for both the sale of soft drinks you add them together. Therefore, the answer is 362(1.75) + 221(2.35).

A student is helping a family member build a storage bin for their garage. They would like for the bin to have a volume of 240 ft3 If they already have the length measured at 8 feet and the width at 6 feet, what is the height needed to reach the desired volume?

(A) 3 feet
(B) 3.5
(C) 4 feet
(D) 5 feet​

Answers

Answer: The answer to your question is D! Brainliest?

Step-by-step explanation:

To find the height needed to reach a volume of 240 ft^3, we can use the formula:

Volume = length x width x height

Substituting the given values, we get:

240 = 8 x 6 x height

Simplifying:

240 = 48 x height

height = 240/48

height = 5

Therefore, the height needed to reach a volume of 240 ft^3 is 5 feet.

Answer: (D) 5 feet.

The area of the shaded area is 3.27 ft²

How to the area of the shaded area?

We can find the area of the shaded area by subtracting the area of the triangle from the area of the sector. That is;

Area of shaded area = Area of sector - area of triangle

Area of shaded area = (60/360 * π * 6²) - (1/2 * 6 * 6 * sin 60)

Area of shaded area = (60/360 * 22/7 * 36) - (1/2 * 36 * 0.866)

Area of shaded area = 3.27 ft²

why would you use a trigonometric function to set-up an application problem instead of a non-trigonometric function

Answers

Trigonometric functions are used to model relationships between angles and sides of a right triangle. They are particularly useful in solving problems that involve angles, distances, heights, and lengths that are difficult to measure directly.

For example, consider a problem that involves finding the height of a building. By measuring the length of the shadow cast by the building at a particular time of day, the angle of the sun's rays can be calculated using trigonometry. Once the angle is known, the height of the building can be determined using the tangent function.

In contrast, a non-trigonometric function may not be able to model the relationship between the given quantities in such problems, and may not provide an accurate solution. Therefore, when a problem involves angles or distances that are not directly measurable, trigonometric functions are typically the best tool for setting up and solving the problem.

when a researcher uses the pearson product moment correlation, two highly correlated variables will appear on a scatter diagram as what?

Answers

When a researcher uses the Pearson product-moment correlation, two highly correlated variables will appear on a scatter diagram as a tightly clustered group of points that form a linear pattern.

The scatter diagram is a visual representation of the correlation between two variables, where one variable is plotted on the x-axis, and the other variable is plotted on the y-axis. If the two variables have a high positive correlation, then the points on the scatter diagram will form a cluster that slopes upwards to the right.

On the other hand, if the two variables have a high negative correlation, then the points will form a cluster that slopes downwards to the right. The tighter the cluster of points, the higher the correlation between the variables.

A large rectangular prism is 5 feet long, 3 feet wide, and 4 feet tall. A small rectangular prism is 2.5 feet long, 1.5 feet wide, and 2 feet tall.
How many small prisms would it take to fill the large prism?
Write your answer as a whole number or decimal. Do not round.

Answers

The answer of the given question based on the  rectangular prism is , , it would take 8 small rectangular prisms to fill the large rectangular prism.

What is Rectangular prism?

A rectangular prism, also known as a rectangular parallelepiped, is a three-dimensional solid object that has six rectangular faces, with opposite faces being congruent and parallel. It is a special case of a parallelepiped in which all angles are right angles and all six faces are rectangles.

To find how many small rectangular prisms will fit inside the large rectangular prism, we need to calculate the volume of each prism and then divide the volume of the large prism by the volume of the small prism.

The volume of the large prism is:

V_large = length × width × height = 5 ft × 3 ft × 4 ft = 60  feet³

The volume of the small prism is:

V_small = length × width × height = 2.5 ft × 1.5 ft × 2 ft = 7.5  feet³

Dividing the volume of the large prism by the volume of the small prism, we get:

number of small prisms = V_large / V_small = 60 ft³ / 7.5 ft³ = 8

Therefore, it would take 8 small rectangular prisms to fill the large rectangular prism.
