1. Fine the mean of the data
2. Find the mean absolute deviation

MEAN: 4

MEAN ABSOLUTE DEVIATION: 2

Step-by-step explanation:

mean: 3 + 2 + 2 + 7 + 6 + 3 + 9 + 0 = 32/8 = 4

4 - 3 = 1

4 - 2 = 2

4 - 2 = 2

4 - 7 = 3

4 - 6 = 2

4 - 3 = 1

4 - 9 = 5

Mean Absolute Deviation: 1 + 1 + 2 + 2 + 2 + 3 + 5 = 16/8 = 2

would highly appreciate it if you would mark me the brainliest~

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
