Answer:
The mean is 12, The median is 13, The mode is 14, and the range is 8.
The second choice is the correct answer.
Explanation:
- I found the mean by adding up all the numbers and dividing by the number of numbers, or sun divided by count. The sum of the numbers was 132, and the count was 11. I divided 132 by 11 to get 12.
- I listed the numbers in order from least to greatest. The data set was: 7, 8, 10, 12, 12, 13, 13, 14, 14, 14, 15
- I found the median by crossing off the number on each end of the data set, and kept going. For example, I crossed off 8, and then 15, and then 10, and then 14 and so on until I got to the middle number. (Keep in mind, if there are two middle numbers, find the mean of them [add them and divide by two])
- The mode is the number that shows up the most in the data set, so I looked at the data set and saw that 14 showed up 3 times, more times than any other number.
- The range is the difference between the greatest and least number (maximum and minimum) so I just subtracted 15 - 7 to get a difference of 8.

Answer:
False
Step-by-step explanation:
4g + 7 = 5g - 1 - g
Simplify:
4g + 7 = 4g - 1
Subtract both sides by 4g:
7 = -1
There are no solutions to this equation.

D on edge
Step-by-step explanation:
2020
We are given the following relation:
y = 4.302 x – 3.293
To solve for the mean value of y when x = 20, what we have
to do is to find for the value of y at x = 20 and the value of y at x = 0. Then
we get the average of the two values.
when x = 0
y(0) = 4.302 (0) – 3.293
y(0) = - 3.293
when x = 20
y(20) = 4.302 (20) – 3.293
y(20) = 82.747
The mean value would be:
mean y = [y(20) + y(0)] / [20 + 0]
mean y = [82.747 + (-3.293)] / 20
<span>mean y = 3.9727 = 3.97</span>
