Solve the formula for x.
V=2πrx+6πr2

Answers

Answer:

x=−18.849556r2+v/6.283185r

Step-by-step explanation:

Step 1: Flip the equation.

18.849556r2+6.283185rx=v

Step 2: Add -18.849556r^2 to both sides.

18.849556r2+6.283185rx+−18.849556r2=v+−18.849556r2

0r 2+6.283185rx=−18.849556r2+v

Step 3: Divide both sides by 6.283185r. 0r2+6.283185rx/

6.283185r = −18.849556r2+v/6.283185r

x=−18.849556r2+v/6.283185r

Let's see

\(\\ \rm\Rrightarrow V=2\pi rx+6\pi r^2\)

\(\\ \rm\Rrightarrow V=2\pi r(x+3r)\)

\(\\ \rm\Rrightarrow \dfrac{V}{2\pi r}=x+3r\)

\(\\ \rm\Rrightarrow x=\dfrac{V}{2\pi r}-3r\)

The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.


Mountain View School Seaside School

0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside


Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

-7x + 8y = 39

Answers

Answer:

-7x + 8y = 39

when x = -9

-7(-9) +8y = 39

63 + 8y = 39

8y = 39-63

8y = -24

Divide both sides by 8

y = - 3

Hope this helps.

Answer:

y = -3

Step-by-step explanation:

=> -7x+8y = 39

Putting x = -9

=> -7(-9)+8y = 39

=> 63+8y = 39

Subtracting 63 to both sides

=> 8y = 39-63

=> 8y = -24

Dividing both sides by 8

=> y = -3

Answer:

3x+8=41

Step-by-step explanation:

Subract by 8 (8-8) (41-8)

3x=33

Divide by 3 on both sides

x=11

Answer:

A : 3x + 8 = 41

B : x = 11

Step-by-step explanation:

For this problem, there are two parts, so I am going to explain A first. So we know that the final cost is going to equal to 41. There are two costs, one of which we know and one of which we don't. The cost we do know of is the special group fee, which is 8. Now we know something plus 8 is going to equal to 41. The second cost is the cost per person, but we don't know how many people there are, so what we do instead is say the is of people x. If it costs the 3 dollars per person, the second cost is 3x. Now we know that

3x + 8 = 41, and that's your answer to part A. For part B, all we have to do is solve it. To do that, the first thing we are going to do is isolate the variable by subtracting 8 form both sides. Now we end up with 3x = 33. To finish solving, we just have to divide both sides by three so we end up with x. Once we do that, we get x = 11, and that's your answer to B. I hope this was helpful and you learned something form this.

Answer:

11/15

Step-by-step explanation:

There's multiple ways to do this problem.

I will explain how to do greatest common factor of the denominator.

Easiest way is to multiply 5*3 to get 15, so now both your denominatiors will be 15.

So then to take care of the numerator, you can multiply the old denominator with 5 by 3 for the numerator. The 2 will turn into a 6.

So then to take care of the other numerator with a 3 as the denominator, you can multiply it by 5. So that 1 will turn into a 5.

That means our new fractions will be 6/15 + 5/15.

Now that the denominators are the same, you can add the numerators and keep the denominators.

Nothing left to simply since 11 is prime.

11/15 is the sum of 2/5 and 1/3.

Write an equation of the line that passes through the y intercept (0,4) and has a slope of -3

Answers

Answer:

y = -3x + 4

Step-by-step explanation:

We'll write the equation in slope-intercept form, which looks like this: y = mx + b. m is the slope, and b is the y-intercept.

In the information given, we know that the slope (m) is -3 and the y-intercept (b) is (0, 4). So, we can say that the equation for this line is y = -3x + 4.

Let me know if you need any more help!

Y= -3x+4 this should be the correct answer because, the y-intercept is 4 and the y-intercept is the same as “b” from the equation y=mx+b and “m” means slope so you insert your slope in the equation. This should give you y= -3x+4. I hope this is helpful!

The box plot shows the number of jumping jacks completed in a workout class by the class members. A box plot uses a number line from 14 to 54, with tick marks every one unit. The box extends from 26 to 49 on the number line. A line in the box is at 40. The lines outside the box end at 15 and 52. The graph is Jumping Jacks Completed, and the line is labeled Number of Jumping Jacks. Which of the following lists the range and IQR for this data? The range is 23, and the IQR is 37. The range is 40, and the IQR is 37. The range is 40, and the IQR is 23. The range is 37, and the IQR is 23.

Answers

To determine the range and IQR (interquartile range) based on the given box plot, let's first define these terms:

- Range: The range is the difference between the maximum and minimum values in a data set.
- IQR: The IQR is the range of the middle 50% of the data values. It is calculated by finding the difference between the third quartile (Q3) and the first quartile (Q1).

In the given box plot:

- The lines outside the box represent the minimum and maximum values.
- The box represents the middle 50% of the data, with the line inside the box representing the median (or second quartile, Q2).
- The distance between the lower whisker and the bottom edge of the box represents the first quartile (Q1), and the distance between the upper whisker and the top edge of the box represents the third quartile (Q3).

Based on the information provided in the box plot, we can determine the range and IQR as follows:

- The minimum value is represented by the lower whisker, which ends at 15.
- The maximum value is represented by the upper whisker, which ends at 52.
- Q1 is located at the bottom edge of the box, which is 26.
- Q3 is located at the top edge of the box, which is 49.

Now we can calculate the range and IQR:

- Range: maximum value - minimum value = 52 - 15 = 37
- IQR: Q3 - Q1 = 49 - 26 = 23

Therefore, the correct statement is:

The range is 37, and the IQR is 23.

Answer:

The range is 37, and the IQR is 23.

Step-by-step explanation:

A box plot (also known as a "box and whisker plot"), is a graph displaying the distribution of a set of data based on a five-number summary.

Five-number summaryMinimum value is at the end of the left whisker.Lower quartile (Q₁) is the left side of the box.Median (Q₂) is the vertical line inside the box.Upper quartile (Q₃) is the right side of the boxMaximum value is at the end of the right whisker.

From the given information, the five-number summary of the Jumping Jacks box plot is:

Minimum = 15Lower quartile (Q₁) = 26Median (Q₂) = 40Upper quartile (Q₃) = 49Maximum = 52

Range

The range is the difference between the maximum and minimum values. Therefore, the range for the data is:

\(\sf Range = 52 - 15 = \boxed{\sf 37}\)

Interquartile range (IQR)

The IQR is the difference between the upper quartile and the lower quartile. Therefore, the IQR for the data is:

\(\sf IQR = Q_3 - Q_1 = 49 - 26 = \boxed{\sf 23}\)

Summary

The range is 37, and the IQR is 23.
