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
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
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.

On his math quiz, Anthony used a protractor to measure an angle. He misread the protractor and thought the angle measured 28°. When he double-checked his work before turning it in, he realized the actual measure of the angle was 32°. What is the percent error for his original measurement?
Answers
Percent Error = (|Measured Value - Actual Value| / Actual Value) * 100
In this case, the measured value is 28° and the actual value is 32°.
|28 - 32| = 4
Percent Error = (4 / 32) * 100
Percent Error = 12.5%
Therefore, the percent error for Anthony's original measurement is 12.5%.

V=πr^2h
You have the diameter which is 2 times to radius. In order to get the radius you half the diameter which is 9.
9 to the second power is 81. Then you multiply it by the height which is 11. 81 x 11 is 891. So 891 x pi would be about 2799.16.
2r=d 2 r = d.
So plug in 18m in as d.
2r=18
/2 /2
r= 9
The volume of a cylinder is v= πr^2h
Use Pi symbol in calculator unless specified to use 3.14
The height is 11m
V=πr^2h
V= π(9)^2(11)
V= π(81)(11)
V= π(891)
V= 2,799.159054348506
So, to the nearest whole number: v= 2,800 m

You are given a triangle with side lengths of 6, 9, and 12. Is the triangle a right triangle? How do you know?
Answers
Answer:
No, it's not
Step-by-step explanation:
You choose the longest side which is 12 and apply the theory of phitagors
The longest side which is the hypotenuse in a right triangle = square root the square sum for each side
So to be a right triangle it should be
\( \sqrt{ {9}^{2} + {6}^{2} } = 10.8 \: \: that \: doesnt \: equal \: 12\)
So it's not a right triangle.
Look at the famous right triangle whose side are 5(hypotenuse), 4, 3
\( \sqrt{ {4}^{2} + {3}^{2} } = 5\)
So it's a right triangle
Right triangle lengths can be checked by the Pythagorean theorem.
This states that a^2+b^2=c^2
a and b are the shorter side lengths, and they form the right angle. c is the hypotenuse, and is the longest length.
Input the values to check if the equation checks out:
6^2+9^2=12^2
36+81=144
117≠144
No, it is not a right triangle. Hope this helps!

Under his cell phone plan, Alexander pays a flat cost of $69.50 per month and $5 per gigabyte. He wants to keep his bill under $85 per month. Write and solve an inequality which can be used to determine gg, the number of gigabytes Alexander can use while staying within his budget.
I don't know how to write inequality
69.50 dollars + 5 dollars is 74.50 dollars add 5 dollars 79.50 add 5 dollars again and 84.50
Answers
Answer- 5g+ 69.50= 85 ; 3.1 (3)
An inequality is an equation with letters and number that sum to ONE whole.
In this case we have a flat cost, which is standalone and 5 dollars per gigabyte which is not standalone. Let G stand for each gigabyte.
This means our equation is 5g(five dollars times each gigabyte used) +69.50 that is gives. He has to keep his entire month under 85 dollars, which means our equation must equal 85. Now our equation will look like this.
Inequality- 5g+ 69.50= 85.
In order to solve how many gigabytes will be used we solve our equation backwards. We subtract 69.50 from 85,because we know that must has already been spent. This gives us 15.50. This means we will have to divided 15.50 into five dollars to see how many gigabytes are spent. 15.50 divided into five is 3.1 gigabytes.
This means Alexander will have to use 3.1 (or 3 if you have to round) gigabytes in order to spend 85 dollars or less per month.
69.50+5(3)>_85
84.50>_85

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

find the degree of 3m^2·n^4
Answers
Answer:
4
Step-by-step explanation:
The degree of a polynomial is the variable with the highest degree, in this case you have two variables and generally, when you have two variables, especially when they're grouped you would add the degrees So for example: \(xy^3 + x^2y^3\). The first term xy^3 has a degree of 4 because x has a degree of 1 and y has a degree of 3, adding those two becomes 4, the second term has a degree of 5 so the degree of the polynomial is 5. In your example, you provided \(3m^2-n^4\), which you can think of as: \(3m^2n^0 * n^4m^0\). Adding the degrees you get 2 and 4 the highest one is 4, so the degree of the polynomial is 4
Answer:
4
Step-by-step explanation:
Here the exponent of n is 4, which is greater than the exponent of m, which is 2. Thus, the degree of this expression is 4.
