Answer:
Mean= 
=13.28 ≈13
For median arrange in ascending or descending order. i am arranging in ascending order
9,11,11,13,15,17,17
cancel from left and right until one number is left
median=13

The solution set for the both equation is (3,0) and (-1,0)
We have given that the equation

We have to determine the solution to the first equation
<h3>
What is the quadratic equation formula?</h3>





Now use this value we have to find the value of y
When x=3 then
y=(3)^2-2(3)-3
y=9-6-3
y=0
When x=-1 then y=1-2(-1)-3
y=1+2-3
y=0
Therefore the solution set for both equations is (3,0) and (-1,0).
