Using the following data, calculate the mean absolute deviation: 7, 2, 8, 5, 9, 9, 5, 6, 8, 1. What is the mean absolute deviation for these data? a 2.2
b 6
c 6.5
d 8

pretty sure the answer is 6

Explanation: Add all the numbers up then divide by how many numbers there are.

Step-by-step: 7 + 2 + 8 + 6 + 9 + 9 + 5 + 6 + 8 + 1

= 60 divided by 10 equals 6

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
