The height (h) of the rectangular prism is: 1.9 feet.

<h3>How to Find the Volume of a Rectangular Prism?</h3>

A rectangular prism has a length (l), height (h), and a width (w). The volume of the rectangular prism is calculated using the formula given as: V = (length)(width)(height).

Given the following parameters:

Volume of the rectangular prism = 30.45 ft^3,

Length (l) = 6.3 ft,

Width (w) = 2.5 ft.

Height of the rectangular prism (h) = ?

Plug in the values

(6.3)(2.5)(h) = 30.45

15.75h = 30.45

15.75h/15.75 = 30.45/15.75

h ≈ 1.9 ft

The minimum score required for an A grade is 83.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Mean of 72.3 and a standard deviation of 8.

This means that $\mu = 72.3, \sigma = 8$
