Answer:

$\frac{V}{\pi r^{2} }$ = h

Step-by-step explanation:

Lets try and get everything we can away from h.

V = $\pi$ $r^{2} h$

Divide $\pi$ $r^{2}$ from both sides of the equation.

Now we end up with:

$\frac{V}{\pi r^{2} }$ = h

Answer:

Weights of at least 340.1 are in the highest 20%.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 330, \sigma = 12$
