Answer:
The expected total amount of time the operator will spend on the calls each day is of 210 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
and standard deviation
, the z-score of a measure X is given by:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
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.
n-values of normal variable:
Suppose we have n values from a normally distributed variable. The mean of the sum of all the instances is
and the standard deviation is ![s = \sigma\sqrt{n}](https://tex.z-dn.net/?f=s%20%3D%20%5Csigma%5Csqrt%7Bn%7D)
Calls to a customer service center last on average 2.8 minutes.
This means that ![\mu = 2.8](https://tex.z-dn.net/?f=%5Cmu%20%3D%202.8)
75 calls each day.
This means that ![n = 75](https://tex.z-dn.net/?f=n%20%3D%2075)
What is the expected total amount of time in minutes the operator will spend on the calls each day
This is M, so:
![M = n\mu = 75*2.8 = 210](https://tex.z-dn.net/?f=M%20%3D%20n%5Cmu%20%3D%2075%2A2.8%20%3D%20210)
The expected total amount of time the operator will spend on the calls each day is of 210 minutes.

Step-by-step explanation:
Answer:
The equation c = 0.02p+149 represents micks commission.
Step-by-step explanation:
Given that:
Amount earned by Nick on sale of each boat = $149
Commission earned = 2% of the purchase price
p represent the purchase price
Commission earned = ![\frac{2}{100}*p](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B100%7D%2Ap)
Commission earned = 0.02*p
Commission earned = 0.02p
Total commission = c = 0.02p + 149
Hence,
The equation c = 0.02p+149 represents micks commission.
