Step-by-step explanation:

The provided information is:

The coefficient of determination $(r^2)$ is determined by formula:

$r^2=1-\dfrac{SSE}{SST}\\\\=1-\dfrac{80.42}{140.58}\\\\=1-0.57\\\\=0.43$

Thus, coefficient of determination is closest to 0.43

15/3 = 5

x = 5

This is my take using algebraic methods.
