find the approximate mean absolute deviation for this list of numbers. [note: type your answer as a decimal number, rounded to the nearest tenth.]
55, 35, 27, 63, 49, 22, 71

15.4

Step-by-step explanation:

mean: (55 + 35 + 27 + 63 + 49 + 22 + 71)/7 = 46

absolute values of differences:

|55 - 46| = 9

|35 - 46| = 11

|27 - 46| = 19

|63 - 46| = 17

|49 - 46| = 3

|22 - 46| = 24

|71 - 46| = 25

The means of the differences is:

(9 + 9 + 19 + 17 + 3 + 24 + 25)/7 = 108/7 = 15.4

a reflection across the x axis and a 90 degree rotation left and right.

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
