Answer:

And we can calculate the deviations from each value like this:






And the mean absolute deviation would be:

Step-by-step explanation:
For this case we have the following dataset given:
101.5 98.7 95.4 92.3 109.8 104.7
We can calculate the mean with the following formula:

And replacing we got:

And we can calculate the deviations from each value like this:






And the mean absolute deviation would be:

Ok? Is there like an equation or something that I can see so then I can help you?

Answer:
x=8
Step-by-step explanation:
You would set them equal to each other to get 9x-13=6x+11.
You would them move 6x over so -6x on both sides. This would then get you 3x-13=11.
Then move the -13 over so add 13 to both sides to get 3x=24
Then get x by itself so divide by 3 to get x=24/3.
Then that simplified is 8
