Answer:

Distribute

(2/5) (a) + (2/5) (b) + (3/5)(a) +(3/5)(c)

Combine like terms

2/5 a + 2/5 b + 3/5 a + 3/5 c

= ( 2/5 a + 3/5 a ) + ( 2/5 b) +(3/5 c)

= a + 2/5 b +3/5 c

What would it mean if the teacher had a MAD of 0

Answers

Answer:

MAD or also called as median absolute deviation is equal to zero. This means that there is no deviation and all the values are the same.

When a given number series is sorted in ascending order, the median is the middle number and that is zero.

MAD is a way to describe variation in a data set.

When a teacher gets MAD of zero, this means all the values are zero.

It would mean that the sum of numbers is equal 0, so the mean is going to be 0 also)
