What is the mean absolute deviation for 7, 5, 1, 6, 2, and 3?
a. 6
b. 3
c. 2
d. 1

To find the Mean Absolute Deviation, you have to find the mean first.
7+5+1+6+2+3=24
24 divided by 6 numbers= 4
The mean is four.
Next you need to find how much is each number from the mean
7=3 from 4              5=1 from 4 etc
You get 3,1,3,2,2,1
Then you find the mean of that. 
3+1+3+2+2+1=12
12 divided by six numbers = 2
The Mean Absolute deviation is 2

You need to divide 210 square inches by 35 inches and that’s going to give you 6 inches and that’s the length of the hypothenuse of the right triangle i hope that this you : )
