28)A regression equation is obtained for a collection of paired data. It is found that the total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083. Find the coefficient of determination.

The coefficient of determination = 0.6291

Step-by-step explanation:

Given: Total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083.

The coefficient of determination is computed as:

Substituting given values, we get

Therefore, the coefficient of determination = 0.6291

360 in^3

Step-by-step explanation:

10x9x8=720

720/2=360

So the reason you divide 720 by 2 is because the formula to solve for a triangular prism says base times width times height divided by 2.
