Using it's concept, it is found that the mean absolute deviation of 2.8 means that the heights differ from the mean by an average of 2.8 inches.
<h3>What is the mean absolute deviation of a data-set?</h3>
- The mean of a data-set is given by the sum of all observations divided by the number of observations.
- The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.
- The mean absolute deviation represents the average by which the values differ from the mean.
In this problem, the mean is given by:
M = (65 + 58 + 64 + 61 + 67)/5 = 63.
Hence the mean absolute deviation is given by:
MAD = (|65-63| + |58-63| + |64-63| + |61-63| + |67-63|)/5 = 14/5 = 2.8.
The mean absolute deviation of 2.8 means that the heights differ from the mean by an average of 2.8 inches.

If you have some thing like x^2 + x + x^3 + x^2 the correct order would be x^3 + x^2 + x^2 + x.
Answer: g(x) -1/2fx-1
Step-by-step explanation: Pretty much you distribute the 1/2f to the x and the 2 then you got you function.
Step-by-step explanation:
Sub in your values
4-4(-3)/2
=4 + 12 /2
=4+ 6
=10
