The requried surface area of the given prism is 1716 square centimeters.
What is the surface area?The surface area is the total area that covers the surface of a three-dimensional object. It is calculated by adding up the area of all the faces or surfaces of the object. For example, the surface area of a cube can be calculated by adding up the areas of all six faces.
Here,
The surface area of the given prism is given as:
Surface area = 5*20 + 10*20 +20*8 + 11*20+2[5*10+16*8]+16*20+20*18
Surface area = 1716 square centimeters
Thus, the requried surface area of the given prism is 1716 square centimeters.

Answers
Answer:
Step-by-step explanation:
n(U)=100%
n(S)=70%
n(W)=15%
n(S union w compliment)=20%
n(s intersection W)=?
n(u)=n(s)+ n(w)+ n(s union w compliment)- n(s intersection w)
or 100%=70% +15%+ 20% - n( s intersection w)
or 100%= 95%- n(s intersection w)
or 100%-95%=n(s intersection w)
or 5%= n( s intersection w)
now;
n(only w)=n(w)- n(s intersection w)
=15%- 5%
=10%
10%of people only like winter season.
i think the question is to find people who only like winter season.
if not then ans is 15% according to question.
a) The illustration of the given information in a Venn diagram is attached.
b) The percentage of people who liked both seasons is 45%.
c) If 180 people liked the summer season only, proportionately, the number of people who liked the winter season only is 300.
How the Venn diagram is illustrated:The Venn diagram, which shows similarities and contrasts, can be illustrated based on the given percentages.
Percentages are one of the ways to depict proportions, which are the equation of two ratios.
The percentage of survey people who liked the summer season = 60%
The percentage of survey people who liked the winter season = 70%
The percentage of survey people who liked none of the seasons = 15%
The percentage of participants who liked one of the seasons = 85% (100% - 15%)
The total percentage of survey people who liked either summer or winter = 130% (60% + 70%)
b) The percentage of survey people who liked both seasons = 45% (130% - 85%)
The percentage that liked only summer = 15% (60% - 45%)
The percentage that liked only winter = 25% (70% - 45%)
c) 180 people liked summer only
180 = 15%
Proportionately, if 180 = 15% of the people, the total number of people = 1,200 (180/15%)
The number of people who liked winter season only = 300 (1,200 x 25%)

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.
