Answer:
MAD means Mean Absolute Deviation. It a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set.
Step-by-step explanation:
A data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. How to solve MAD is start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values.

Answer:
The teacher have 32 students.
Step-by-step explanation:
Firstly, 'if she gave each students 3 bookmarks, she would have 21 bookmarks left.' This means that 3x + 21 = amount of bookmarks available. Here the x is the number of students.
Then, 'if she gave each students 5 bookmarks, she would be short of 53 bookmarks.' This means that 5x - 53 = amount of bookmarks avalable.
Since both equations all equal to the same quantity, then we know that:
3x + 21 = 5x - 53
Finally, we just need to rearrange the equation to make x the subject.
3x + 21 = 5x - 53
3x = 5x - 53 - 21
3x = 5x - 74
3x - 5x = - 74
- 2x = - 74
- 2x ÷ -2 = - 74 ÷ -2
x = 37
Then, just to make sure, we put the number of students into the equations.
3x + 21 = 5x - 53
3 × 37 + 21= 5 × 37 - 53
111 + 21 = 185 - 53
132 = 132
This means that x does equal to 37.
-16 + 24 = 8
Because 24 - 16 = 8
