Ps: I am not sure my method of finding area is correct

I will put the method in the comments

how to find the P: To find the p of Any Shape is the same formula, adding all the sides up. So to find the p of this shape all you need to do is add all the sides up. 3+12.5+7.5+13. Add these up and you get the P

Given function for remaining amount of money over $2500 earnings E(x) = x-2500.

And function for total commission earn C(x) = 0.02x.

We need to find the composite function that would use to calculate your commission earned if you sold $6000.

The composite function that would use to calculate your commission earned would be : C of E(x).

That is C(E(x)) = (C o E)(x) = 0.02(x-2500).

<em>Now, in order to calculate the commission earned if you sold $6000, we need to plug x=6000 in (C o E)(x) = 0.02(x-2500) composite function.</em>

(C o E)(x) would become (C o E)(6000).

<h3>Therefore, correct option is first option (C o E)(6000).</h3>

A line for tickets to a Broadway show had a mean waiting time of 20 minutes with a standard deviation of 5 minutes.

Answer:

5.48% of the people in line waited for more than 28 minutes

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 waiting time of 20 minutes with a standard deviation of 5 minutes.

This means that $\mu = 20, \sigma = 5$

What percentage of the people in line waited for more than 28 minutes?

The proportion is 1 subtracted by the p-value of Z when X = 28. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{28 - 20}{5}$

$Z = 1.6$

$Z = 1.6$ has a p-value of 0.9452.

1 - 0.9452 = 0.0548.

As a percentage:

0.0548*100% = 5.48%

5.48% of the people in line waited for more than 28 minutes
