Answer:

True

Step-by-step explanation:

Considering the above definition of Pooled Variance, the correct answer is TRUE.

This helps to provide greater precision estimates of variance.

The sine ratio that was applied in step 2 is incorrect, therefore, the first error is in: B. step 2.

<h3>How to Apply the Sine Ratio?</h3>

The sine ratio that is applied when we want to solve a right triangle is, sin ∅ = opposite length / hypotenuse length.

In step 2, the sine ratio applied is wrong because:

  • ∅ = W
  • Opposite length = XZ
  • Hypotenuse length = y

Thus, we should have:

sin(W) = XZ/y

The first error is in: B. step 2.

9) yes, he is correct.   

50% as a decimal would be 0.50
7% as a decimal would be 0.07

10)Buy and Bye has a greater discount because 30% as a decimal is 0.30 and 1/4 as a decimal is 0.25.

0.30 is bigger than 0.25 so it is a bigger discount
