Sindrei [870]

Answer:

Step-by-step explanation:

Given that the significance level of 2% = α

Because the the null hypothesis is true so it is denoted by α it also defined as the level of significance =1 - confidence level = 1 - 0.02 = 0.98.

Helga [31]

Answer:

Volume of a right prism = 65 cubic inches

Its height is increased by a factor of 20.

To find:

The new volume of the prism if the other dimensions do not change.

Solution:

The volume of a prism is:

$Volume=Bh$

Where, B is the base area and h is the height.

A right prism has a volume of 65 cubic inches.

$65=Bh$

The height of prism is increased by a factor of 20. So, the new volume is:

$Volume=B(20h)$

$Volume=20(Bh)$

$Volume=20(65)$

$Volume=1300$

The volume of the new prism is 1300 in³.

Therefore, the correct option is B.
