Answer:

Step-by-step explanation:

The formula for the volume of a cylinder of base radius r and height h is

V = π·r²·h. Get the radius and height information from the original problem statement and substitute these values into this formula.

For example, if the radius is 3 cm and the height is 4.5 cm, then the volume of this particular cylinder is

V = π·(3 cm)²·(4.5 cm) = 127.2 cm³ (this is an EXAMPLE only)

Express algebraically. The product of 6 and a number is 120.

Gekata [30.6K]

Answer:

6x = 120

Step-by-step explanation:

Let the number be " x ".

The product of 6 and a number,

6 * x = 6x

The product of 6 and a number is 120,

6x = 120

Therefore,

the algebraic form is 6x = 120.

For an intramural sports program at a particular college, the time to run one mile is recorded for 200 male students in the prog

Greeley [361]

Answer:

Devon has the lower z-score, so he ran the mile faster relative to his gender.

Step-by-step explanation:

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.

Who ran the mile faster relative to their gender?

The lower the percentile of time ran, the faster. So whoever has the lower z-score ran the mile faster.

Devon

His best time to run the mile is 6.6 minutes.

These times are approximately normal with mean 8 minutes and standard deviation 1 minute.

We have to find Z when $X = 6.6, \mu = 8, \sigma = 1$ . So
