Answer:

(D)Isabella should have divided the product of $12\pi \:cm^2$ , and 9 by 3 to get $V=\frac{1}{3}*12\pi*9$ .

Step-by-step explanation:

Isabella uses the expression: $V=\frac{1}{3}*12^2*9*\pi$ to find the volume of a cone with the following dimensions:

Height=9cm

Base Area = $12\pi \:cm^2$

Volume of a Cone , $V=\frac{1}{3}*Base\:Area*Height=\frac{1}{3}\pi r^2 h$

$=\frac{1}{3}*12\pi*9$

Since the base area of the cone = $12\pi \:cm^2$ , Isabella should have divided the product of $12\pi \:cm^2$ , and 9 by 3 to get $V=\frac{1}{3}*12\pi*9$ .

What is the volume of a frustum of a rectangular pyramid if one base has measurements 6 ft. × 8 ft., the other base has measurem

RoseWind [281]

To solve this, we use the formula for the volume of the frustum of a cone which is expressed as:

<span>V= (H/6)[WL + (W+a)(L+b) + ab]
</span>V = 3/6 [(6 ft. × 8 ft.) + (6 + 14)(18 + 8) + (<span>14 ft. × 18 ft.)]
</span>V = 409.98 ft^3 <-----OPTION C

Answer:

At the 95% confidence level, management should not conclude that the percentage of rework for electrical components is lower than the rate of 12% for non-electrical components, since the upper bound of the confidene interval, which is 0.1339, is higher than 0.12.

Step-by-step explanation:

To reach a conclusion, we have to observe the confidence interval.

Should management conclude that the percentage of rework for electrical components is lower than the rate of 12% for non-electrical components?

Is the upper bound of the confidence interval lower than 12% = 0.12?

If yes, it should conclude that this percentage is lower.

Otherwise, it cannot conclude.

Confidence interval:

0.0758 to 0.1339

0.1339 is higher than 0.12.

So.
