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.

$75= Cassidy's goal
c= number of cupcakes
a= $6 already raised
EQUATION:
75<$3c + a
substitute $6 in for a
75< $3c + 6
subtract 6 from both sides
69<3c
divide both sides by 3
23<c
Cassidy needs to sell at least 23 cupcakes to reach her goal of $75.
Answer:
FALSE: Cassidy will need to sell any number of cupcakes greater than 12 to reach her goal.
TRUE: Cassidy will need to sell any number of cupcakes greater than 23 to reach her goal.
Hope this helps! :)
