Sample mean=?


Answer is (4,3)
=============================
Add up the x coordinates to get 9+(-1) = 8. Divide this over two and we end up with 8/2 = 4
Repeat for the y coordinates: 9+(-3) = 6, which cuts in half to get 6/2 = 3
The midpoint is at (4,3)
-------
The midpoint formula is
where (x1,y1) and (x2,y2) are the endpoints.
It would be 24 total windows and 20 windows without leaks. You could possible write it as 24:20 or 24 to 20 or 24/20.
