Raphael wants to create a histogram to display the results of a survey in which his coworkers were asked how many hours they spend on the Internet each week. The results of the survey are shown below.

{14, 22, 10, 6, 9, 3, 13, 7, 12, 2, 26, 11, 13, 25}

Match each interval with its corresponding frequency.

Answers

Answer 1

To create a histogram, we need to divide the range of the data into a set of intervals or "bins" and count the number of data points that fall in each bin. We can then represent this information using a bar chart, where the height of each bar corresponds to the frequency (i.e., number of data points) in that bin.

To determine appropriate bin intervals, we can use the range of the data and the number of bins to create equal-width intervals. For example, we could create 5 bins of width 5:

Bin 1: 2 - 6 Bin 2: 7 - 11 Bin 3: 12 - 16 Bin 4: 17 - 21 Bin 5: 22 - 26

We can then count the number of data points that fall in each bin:

Bin 1: 2 Bin 2: 4 Bin 3: 3 Bin 4: 0 Bin 5: 3

Therefore, the intervals and their corresponding frequencies are:

Interval: 2 - 6 Frequency: 2

Interval: 7 - 11 Frequency: 4

Interval: 12 - 16 Frequency: 3

Interval: 17 - 21 Frequency: 0

Interval: 22 - 26 Frequency: 3

We can then use this information to create a histogram, where the x-axis represents the intervals and the y-axis represents the frequencies, with each bar corresponding to an interval and having a height equal to the frequency in that interval.

Answers

Answer: To solve this problem, we need to use the continuous compound interest formula:

A = Pe^(rt)

where A is the amount in the account, P is the initial principal, e is the mathematical constant e (approximately 2.71828), r is the annual interest rate (as a decimal), and t is the time in years.

For Michael's account, we have:

A = 1000e^(0.0475t)

For Peter's account, we have:

A = 1200e^(0.0425t)

We want to find the time it takes for each account to reach $1,800. So we can set up the following equations:

1000e^(0.0475t) = 1800

1200e^(0.0425t) = 1800

We can solve each equation for t by taking the natural logarithm of both sides and isolating t:

ln(1000) + 0.0475t = ln(1800)

ln(1200) + 0.0425t = ln(1800)

Subtracting ln(1000) or ln(1200) from both sides, we get:

0.0475t = ln(1800) - ln(1000)

0.0425t = ln(1800) - ln(1200)

Dividing both sides by the interest rate and simplifying, we get:

t = (ln(1800) - ln(1000)) / 0.0475 ≈ 10.16 years for Michael's account

t = (ln(1800) - ln(1200)) / 0.0425 ≈ 10.62 years for Peter's account

Therefore, Michael's account will grow to $1,800 first, after about 10 years (rounded to the nearest whole number).

Answers

Let x be the amount that Jaclyn spent on clothes.

According to the problem, Tracy spent $34 less than 3 times what Jaclyn spent, which can be expressed as:

3x - 34

And we also know that Tracy spent $26. So we can set up an equation:

3x - 34 = 26

To solve for x, we can add 34 to both sides of the equation:

3x = 60

And then divide both sides by 3:

x = 20

Therefore, Jaclyn spent $20 on clothes.

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).

Answers

The probability of drawing a red paper clip first and a blue paper clip second is 15/132 or approximately 0.1136.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.

The probability of drawing a red paper clip on the first try is 3/12, because there are 3 red paper clips out of 12 total paper clips in the drawer. Once a paper clip has been removed, there are 11 paper clips remaining, so the probability of drawing a blue paper clip on the second try is 5/11, because there are 5 blue paper clips remaining out of the 11 total remaining paper clips.

The probability of both of these events occurring is the product of their individual probabilities, so the probability of drawing a red paper clip first and a blue paper clip second is:

(3/12) * (5/11) = 15/132

Answers

The predicted total number of calories for a food containing 25 grams of fat is approximately 483.55. 

The equation for the least-squares regression line is:

z = 13.198x + 153.6

where ŷ= predicted value of y (total calories), x = value of the predictor variable (grams of fat), 13.198= slope of the line, and 153.6= y-intercept of the line.

To find the predicted total calories for a food with 25 grams of fat, simplify by substituting x = 25 into the equation.

z = 13.198x + 153.6

ŷ = 13.198(25) + 153.6

ŷ = 329.95 + 153.6

z = 483.55

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

Therefore, the probability of picking one bolt and one nut is 1/2 or 50%.

#SPJ4

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.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It involves the study of the properties of trigonometric functions such as sine, cosine, and tangent, as well as their applications in solving problems involving angles and distances.

Trigonometry is commonly used in fields such as physics, engineering, navigation, surveying, astronomy, and many others. It is also an important part of mathematics education, often taught in high school and college-level courses.

The basic concepts of trigonometry include the definitions of the six trigonometric functions (sine, cosine, tangent, cosecant, secant, and cotangent), the Pythagorean theorem, and the unit circle. With these concepts, it is possible to solve a wide range of problems involving angles and distances, including calculating heights, distances, and angles in a variety of real-world applications.

We can use the following trigonometric identity to find the value of cotangent in terms of sine and cosine:

[tex]cot(a) = cos(a) / sin(a)[/tex]

To find cos(a), we can use the Pythagorean identity:

[tex]sin^2(a) + cos^2(a) = 1[/tex]

We know that sin(a) = 6/7, so we can solve for cos(a):

[tex]cos^2(a) = 1 - sin^2(a)[/tex]

[tex]cos^2(a) = 1 - (6/7)^2[/tex]

[tex]cos^2(a) = 1 - 36/49[/tex]

[tex]cos^2(a) = 13/49[/tex]

[tex]cos(a) = ±\sqrt(13/49)[/tex]

Since we know that tan(a) < 0, we know that a is in the second or fourth quadrant, where cosine is negative. Therefore, [tex]cos(a) = -\sqrt(13/49)[/tex].

Now we can find cot(a):

[tex]cot(a) = cos(a) / sin(a)[/tex]

[tex]cot(a) = (-\sqrt(13/49)) / (6/7)[/tex]

[tex]cot(a) = -(\sqrt(13)/6)[/tex]

when utilizing a matlab built-in ode solver, in the function for one's states the variable for the state derivatives must be organized as a column vector. group of answer choices true false

Answers

It is true to say that when utilizing MATLAB's built-in ode solver, the function for one's states the variable for the state derivatives must be set as column vectors.

The Ordinary Differential Equation (ODE) solvers in MATLAB solve initial value problems with a varient state of properties. They consider state spaces as a column vector. For example, two solve a second degree ODE, It's two states in state space has to be arranges in a 1x2 column vector to pass it into a ODE solver.

Initial value problems with different attributes can be solved using the

ODE solvers in MATLAB.

Here the first ODE is of third order, so it will be converted to three equivalent first order ODEs. The second ODE is second order, so it will be converted to two equivalent first order ODEs.These solver can be used to solve the different type like the differential algebraic equations (DAEs), problems involving a mass matrix, and fully implicit problems.

.

Answers

a) The expression for the amount of pure copper sulfate in 3x liters of 25% solution is  0.675x.

b) The percentage of pure copper sulfate in the resulting solution is 39.375%.

Percent compositionTo find the amount of pure copper sulfate in 3x liters of 25% copper sulfate solution, we can first calculate the amount of copper sulfate in the solution and then multiply by the percentage of pure copper sulfate.

Since the solution is 25% copper sulfate, we know that there are 0.25(3x) = 0.75x liters of copper sulfate in the solution.

The amount of pure copper sulfate in the solution is given by 0.9 times the amount of copper sulfate. Therefore, the expression for the amount of pure copper sulfate in 3x liters of 25% copper sulfate solution is:

0.9(0.75x) = 0.675x

To find the percentage of pure copper sulfate in the resulting solution, we need to calculate the total amount of pure copper sulfate in the solution and divide by the total volume of the solution.

The amount of pure copper sulfate added from the 90% copper sulfate solution is 0.9x liters.

The amount of pure copper sulfate in the 25% copper sulfate solution is 0.675x liters.

The total amount of pure copper sulfate in the resulting solution is:

0.9x + 0.675x = 1.575x

The total volume of the resulting solution is:

x + 3x = 4x

To find the percentage of pure copper sulfate in the resulting solution, we divide the amount of pure copper sulfate by the total volume of the solution and multiply by 100:

(1.575x / 4x) * 100 = 39.375%

Therefore, the percentage of pure copper sulfate in the resulting solution is 39.375%.

Shannon and Leslie want to carpet is 16 1/2‘ x 16 1/2‘ square room. They cannot put carpet under the entertainment system that jets out. In square feet, what is the area of the space with no carpet?

Answers

The area of space with no carpet is 268.25 sq ft.

In order to calculate the area of square room we have to subtract the section that is not carpeted from the total area of the room.

The given dimensions of the room is 16 1/2‘ x 16 1/2‘ square room

therefore,

16.5 x 16.5 = 272.25 sq ft

now if we consider that the entertainment system is 2 feet in measurement then,

2 x 2 = 4 sq ft

hence, the space with no carpet is

271.25 - 4

= 268.25 sq feet

The area of space with no carpet is 268.25 sq ft.
