The absolute distance of the Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.
<h3>What is Mean?</h3>
Mean is simply defined as the average of the given set of numbers. The mean is considered as one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.
<h3>What is the mean absolute deviation?</h3>
Mean refers to the average of the observation and deviation means the variation from the present standard.
Given
Robin’s scores: 99, 108, 102, 107, 119
Mean = 107
MAD = 5.2
Evelyn’s scores: 125, 137, 138, 145, 145
Mean = 138
MAD = 5.6
The absolute distance of the Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.

Answer:
x^2 -7x-18
Step-by-step explanation:
(x-9)(x+2)
FOIL
first x*x = x^2
outer 2x
inner -9x
last -9*2 =-18
Add together
x^2 +2x-9x-18
Combine like terms
x^2 -7x-18
