What is the mad of 5,7.50,8.25,8,9.75,10.25,11,10.75
a 13
b 8.81
c 6
d 1.63

1.63

Step-by-step explanation:

first we find the average of the numbers listed...do this by adding up all the numbers, then dividing by how many numbers there are.

(5 + 7.5 + 8.25 + 8 + 9.75 + 10.25 + 11 + 10.75) / 8 = 70.5 / 8 = 8.8125

now find the distance between the average and each of ur numbers IGNORE ALL NEGATIVE SIGNS

5 - 8.8125 = 3.8125

7.5 - 8.8125 = 1.3125

8.25 - 8.8125 = 0.5625

8 - 8.8125 = 0.8125

9.75 - 8.8125 = 0.9375

10.25 - 8.8125 = 1.4375

11 - 8.8125 = 2.1875

10.75 - 8.8125 = 1.9375

now take the average of those numbers

(3.8125 + 1.3125 + 0.5625 + 0.8125 + 0.9375 + 1.4375 + 2.1875 + 1.9375) / 8 =

13/8 = 1.625...rounds to 1.63 <=== this is ur MAD
