Find the following measure for this figure.

Svetllana [295]

Answer: first option.

Step-by-step explanation:

The formula you must use to calculate the volume of the figure shown is the following:

$V=\frac{BH}{3}$

Where B is the area of the base and H is the height.

Assuming that the base of the pyramid is a square, you have that B is:

$B=(10units)^2=100units^2$

Substitute values into the formula, Then you obtain:

$V=\frac{(100units^2)(12units)}{3}=400units^3$

The width of a casing for a door is normally distributed with a mean of 24 in and a standard deviation of 0.14 in. The width of

Galina-37 [17]

Answer:

0.2296 = 22.96% probability that the width of the casing exceeds the width of the door by more than 0.25 in.

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.

Subtraction of normal variables:

When we subtract normal variables, the mean is the subtraction of the means, while the standard deviation is the square root of the sum of the variances.

The width of a casing for a door is normally distributed with a mean of 24 in and a standard deviation of 0.14 in.

This means that $\mu_{C} = 24, \sigma_{C} = 0.14$
