C. y+4=-3(x-3)

Step-by-step explanation:

The point-slope format is a way to represent the equation of a line. It involves using a point on the line and relating it to the slope in such a way that one can find any point on the line using the equation. One is asked to find the equation of a line in point-slope form. The general format for the point-slope form of a line is the following;

y-h=m(x-k)

Where the point on the line that is being used is ( h,k ). The parameter () represents the slope or rate of change in the line. The slope is often referred to as the ( $\frac{rise}{run}$ ) and can be found using the following formula.

$\frac{y_2-y_1}{x_2-x_1}$

Where ( x_1,y_1 ) and ( x_2,y_2 ) are points on the line. As one can see the following points can be found on the line:

(3,-4), (0, 5)

Substitute these points into the slope formula and solve for the slope;

$\frac{y_2-y_1}{x_2-x_1}$

= $\frac{(5)-(-4)}{(0)-(3)}$

= $\frac{5+4}{0-3}\\$

= $\frac{9}{-3}$

Now substitute the slope into the given formula. As per the problem, one is supposed to use the point ( 3, -4 ) in the formula.

y-h=m(x-k)

Substitute the slope;

y-h=-3(x-k)

Substitute the point;

y+4=-3(x-3)

A demand of 38.1225 pies has an 8% probability of being excedeed.

Step-by-step explanation:

Problems of normally distributed samples can be 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:

$\mu = 31.8, \sigma = 4.5$
