Afootball coach recorded his team's game scores over a football seasons. the scores are 21,45,21,14,21,28,24,14,24,28. a) find the mean absolute deviation of the data. round to the nearest tenth. b) interpret the mean absolute deviation of the data within the context of the problem. c) explain how removing the outlier, 45, affects the mean absolute deviation.

A.) MAD 5.8

Step-by-step explanation:

21+45+21+14+21+28+24+14+24+28= 220. 220/10=22 mean. Take each number in set and add or subtract each number by 22.

1+23+1+8+1+6+2+8+2+6=58/10=5.8 mad

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
