Answer: y = 6
Step-by-step explanation:
1. Subtract 7 from both sides to isolate -2y.
-2y = -12
2. Divide both sides by -2 to isolate the y.

The data given represents the number of gallons of coffee sold per hour at two different coffee shops.
Coffee Ground
1.5 20 3.5
12 2 4
11 7 2.5
9.5 3 5
Perks A Lot
10 3.5 3
5 2.5 7
8 5.5 9.5
6 9 4.5
Compare the data and use the correct measure of center to determine which shop typically sells the most amount of coffee per hour. Explain.
Perks A Lot, with a mean value of 6.125 gallons
Perks A Lot, with a median value of 6.125 gallons
Coffee Ground, with a mean value of 6.75 gallons
Coffee Ground, with a median value of 6.75 gallons
Answers
To calculate the mean, we add up all the values and divide by the total number of values. To calculate the median, we arrange the values in order from smallest to largest and find the middle value. If there are an even number of values, we take the average of the two middle values.
Using these methods, we get:
For Coffee Ground:
Mean = (1.5 + 20 + 3.5 + 12 + 2 + 4 + 11 + 7 + 2.5 + 9.5 + 3 + 5) / 12 = 6.75 gallons
Median = (2 + 2.5 + 3 + 3.5 + 4 + 5 + 7 + 9.5 + 11 + 12 + 20 + 9.5) / 2 = 6.75 gallons
For Perks A Lot:
Mean = (10 + 3.5 + 3 + 5 + 2.5 + 7 + 8 + 5.5 + 9.5 + 6 + 9 + 4.5) / 12 = 6.125 gallons
Median = (3.5 + 3 + 4.5 + 5 + 5.5 + 6 + 7 + 8 + 9 + 9.5 + 10 + 2.5) / 2 = 6.125 gallons
Based on these calculations, we can see that both shops have the same median value of 6.75 gallons. However, the mean value for Coffee Ground is slightly higher at 6.75 gallons compared to Perks A Lot's mean value of 6.125 gallons.
Therefore, we can conclude that Coffee Ground typically sells the most amount of coffee per hour, based on the mean value. However, since the median values are the same for both shops, it's possible that there is some variability in the amount of coffee sold at each shop, and further analysis may be necessary to make a more definitive conclusion.

The figure shows a line graph and two shaded triangles that are similar:
A line is shown on a coordinate grid. The x-axis values are from negative 35 to positive 35 in increments of 7 for each grid line. The y-axis values are from negative 5 to positive 5 in increments of 1 for each grid line. The line passes through the ordered pairs negative 28, negative 4, and 0, 0, and 28, 4.

Find the surface area of the rectangular prism. In question 2 you plugged the length, width, and height into the formula, now in this question find the surface area.
length = 35.7 m
width = 25.5
height = 15.1
What is the surface area?
S.A=2lh+2lw+2hw
Answers
Answer:
The answer to your problem is, In the picture below.
Step-by-step explanation:
1. Given the length, width and height find the volume, surface area and diagonal of a rectangular prism:
h, l and w are known; find V, S and dV = l x w x hS = 2 (lw + lh + wh)d = \(\sqrt{(l^{2} + w^{2} + h^{2} }\)2. Given the surface area, length and width find the height, volume and diagonal of a rectangular prism:
S, l and w are known; find h, V and dh = (S - 2lw) / (2l + 2w)V = lwhd = \(\sqrt{(l^{2} + w^{2} + h^{2} }\)3. Given the volume, length and width find the height, surface area, and diagonal of a rectangular prism
V, l and w are known; find h, S and dh = V / lwS = 2(lw + lh + wh)d = \(\sqrt{(l^{2} + w^{2} + h^{2} }\)4. Given the diagonal, length and width find the height, volume and surface area of a rectangular prism:
d, l and w are known; find h, V and Sh = \(\sqrt{d^{2} - l^{2} - w^{2} }\)V = lwhS = 2(lw + lh + wh)Thus the answer to your problem is, In the picture down below:
25.5m x 15.1m = 385.05m x 2 = 770.1
35.7m x 15.1m = 539.07 = 1078.14
1820.7 + 770.1 + 1078.14 = 3668.94m. Squared

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.
