The data below shows the number of hours mrs. Diaz volunteered each month for 8 months. 20,12,27,23,18,20,30,26 the mean of the data is 22 hours what is the mean absolute deveation data

Given :

Data given : 20 , 12 , 27 , 23 , 18 , 20 , 30 , 26 .

Mean of the data , m = 22 .

To Find :

The mean absolute deviation of given data .

Solution :

We know , mean deviation(M.D) across mean is given by :

Therefore , the mean absolute deviation is 4.5 .

Hence , this is the required solution .

step-by-step explanation:

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
