The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.
Mountain View School Seaside School
0 5, 8
9, 8, 2, 0 1 0, 1, 2, 5, 6, 8
8, 7, 6, 5, 5, 4, 4, 3, 1, 0 2 5, 5, 7, 7, 8
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
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.
Which inequalities would have an open circle when graphed? Check all that apply.

-2.5 Less-than-or-equal-to m
x > 5.4
One-half less-than x

Answers
An open circle is used to graph strict inequalities, which means the inequality does not include the value at the boundary. The inequalities that would have an open circle when graphed are:
x > 5.4
One-half less-than x
x > 0
if an inequality states less than OR equal to that means the circle will be closed when graphed

Mary purchased 12 candy bars for $14.04
Answers
Happy Pride Month!
Answer:
12c=$14.04
Step-by-step explanation:
First lets find out how much each candy bar cost
14.04/12=1.17
so
$1.17*12 = $14.04
so d is the correct answer becuase you would need to multiply the cost of each candy which would be $1.17 by how many candy bars you have which is 12 then get the answer of the total cost that would be $14.04

13 × 1700
13 × 17× 100

So the answer is 22100
13 x 1.7 =22.1
130 x 17 =2210
13 x 1700 = 22100
Explanation: i believe your learning about how to move your decimal place. If you see the given information 17 is the number we are looking at. When the first equation comes up, there’s a decimal making 17 -> 1.7 . Then you move the decimal in the other direction making the 17. turn to 170. then 1700. Making your answer 22100

Basically what you do is multiply the distance by the time, for example:
7 1/2 miles = 1/2 hour
so to get the amount of miles in one hour you get the miles and times it by two so it would go like this:
7 1/2 | 15 |
= | = |
1/2 | 1 |
then for one and a half you get the 1 hour answer and add the first one like this:
22.5 miles = 1 1/2 miles

Remember!!! Trig Functions: Sinθ=Opposite/Hypotenuse, Cosθ=Adjacent/Hypotenuse, tanθ=Opposite/Adjacent (An easy way to remember is SOH CAH TOA)
For this particular problem you need to find the opposite side and the hypotenuse is given and so is the angle. So we can plug into Sinθ=Opposite/Hypotenuse in our calculator:
Sin(63°)=x/8

What is 8/9−(2/3) 2 ?
Answers
Answer: -4/9
Step-by-step explanation:
8/9−(2/3) 2
First, you look at the parenthesis. (2/3)
There is nothing to do with it so you take it out of the parenthesis
8/9 - 2/3 * 2
Now multiply: 2/3 * 2 = 4/3
Now you need to subtract. But the number don't have a common denominator.
Find a common denominator between 9 and 3.
3 can go into 9 three times, so times 3 by 3 to get 9
Now you can subtract 8/9 - 12/9 = -4/9
Answer:
\(-\frac{4}{9}\)
Step-by-step explanation:
2 • 2 = 4
4/3 -----> 12/9
\(\frac{8}{9} - \frac{4}{3} \\\\8 - \frac{12}{9} \\\\-\frac{4}{9}\)
