Answer:
Step-by-step explanation:
- MAD is simply the average distance that all of the numbers in your data set are from the mean.
- Your first step is to put your data in order, then determine the mean.
- Let’s look at this data set:
0.3, 0.5, 0.9, 1.1
- The mean of this data set is 0.7
- Starting with the lower extreme, and checking every number in your data set, determine how far each number is from the mean.
- First, put the numbers in numerical order, from least to greatest.
- Determine the distance each number is from 0.7.
- 0.3=0.4
- 0.5=0.2
- 0.9=0.2
- 1.1=0.4
- Add up all of the distances.
- Total distance from the mean (12) ÷ 4 numbers in our data set = a mean absolute deviation of 3.
I added a PowerPoint that I made so that if you didn't understand it you could read off of it.

- Point A = 3/10
- Point B = 2/5
- Point C = 9/10
- Point D = 7/10
====================================
Explanation:
Point A is located at 0.3; each tickmark represents 0.1
0.3 as a fraction is 3/10 because 3 is in the tenths decimal place. This doesn't reduce.
----
Point B is at 0.4 which converts to 4/10 and then that reduces to 2/5. Divide both parts of 4/10 by 2 to get to 2/5
----
Point C is at 0.9 which converts to 9/10. That's as simplified as that fraction gets.
----
Point D is at 0.7 so it becomes 7/10. That doesn't reduce either.
7ab + 5 is going to be the answer because I solved it and that's the answer
41 time 11 =431 plus 3 =434
