Answer:
4 inches
Step-by-step explanation:
The volume of a box is the product of its dimensions:
V = LWH
Fill in the given information and solve for the unknown value.
30 in³ = (3 in)(2.5 in)H
30 in³/(7.5 in²) = H . . . . . . . divide by the coefficient of H
H = 4 in . . . . . evaluate
The height of the box is 4 inches.

Step-by-step explanation:
Answer:
The variable x will follow a geometric distribution, with mean = 3 and standard deviation = 3.46.
The values for P(x) are:

Step-by-step explanation:
This kind of random variables can be descripted by the geometrical distribution.
This distribution shows the probability of having an amount of "failures" before the first "success" (or the other way).
Let x be the number of trustworthy FBI agents tested until someone fails the test. The probability of failing a test is p=0.25
Then, the probability of x is:

The values for the first x are:

This probability will be descending as the the variable x increases.
The mean is:

The standard deviation is:
