The number of story books owned by eight classmates is shown below:

8, 9, 9, 7, 8, 6, 9, 8

Part A: What is the mean of the data? Show your work. (4 points)

Part B: Use your answer from Part A to calculate the mean absolute deviation for the data. Show your work.

Answer to part A: 8

Explanation:To solve this, first you would add up all the numbers which you would get 64, next you divide by the count which is 8 classmates and 64 divided by 8 is 8.

Answer to part B:0.75

Explanation: You calculate how far away each data point is from the mean using positive distances, once you add the deviations together you divide the sum by the number of data points(8).

Iam not sure , but probably 750 or 7.5

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.
