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:

Answer:
Given the graph
and 
We have to find the value of k;
Since, g(x) = f(x) +k

Subtract
from both sides we get;

Add 2 to both sides we get;

Simplify:

or
k = 5
Therefore, the value of k = 5
