The 69.15 percentile corresponds to 0.500 standard deviations above the mean. If 70 is 10*.500 = 5 units above the mean, then the mean is 65.
I put it them on a graph, they look like a straight line to me. That makes it Linear!

Option: D
Horizontal stretching.
<h3><u>
Step-by-step explanation:</u></h3>
We have to find the effect on the graph of the function f(x)=2x when it is replaced by f(0.5 x).
We know that when a parent function f(x) is replaced by f(kx) then either the graph is stretched horizontally or shrinked horizontally.
if k>1 then the graph is shrinked horizontally.
if k<1 then the graph is stretched horizontally.
Hence here k=0.5<1 so the graph of the function is stretched horizontally.
Well this is easy. FOIL will help later on. For now (12-2) equals 10. Then add 12 and you get 22.
Brainliest answer you will see.
