Answer:
I'm going to write both of these because maybe you have a fill in the blank question. I don't know.

Simplify:

Step-by-step explanation:
is the equation of a circle with center (h,k) and radius r.
You are given (h,k)=(4,5) because that is the center.
You are given r=9 because it says radius 9.
Let's plug this in.

Simplify:

Answer:
there are 9 possibilities I think
It would be: 15/4 = 3 3/4
In short, Your Answer would be 3 3/4
Hope this helps!
The 1, 2, 3 I’m not sure bout the 4th one
8, 8, 8, 8, 8, 9, 9, 9, 9 would work as a sequence.
Median: 8
Mean: 8.4444....
