You just divide 124/3 by 2 and you get 62/3
Answer:
The expected total amount of time in minutes 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:

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 a normal variable:
For the sum of a sample of n values, the mean is of
and the standard deviation is of 
Average 2.8 minutes
This means that 
75 calls each day.
This means that 
What is the expected total amount of time in minutes the operator will spend on the calls each day?

The expected total amount of time in minutes the operator will spend on the calls each day is of 210 minutes.
We have been given an equation that represents the distance an airplane travels in Miles (d) is related to the time in seconds (t).
A. Upon substituting t=1 in our equation we will get,
We can see that our plane is travelling at rate of 0.15 miles per second.
Therefore, plane is flying at the rate of 0.15 miles per second.
B. To find distance traveled by airplane in 30 seconds we will substitute t=30 in our given equation.
Therefore, plane will travel 4.5 miles in 30 seconds.
C. To find time it will take to travel 12.75 miles we will substitute d=12.75 in our given equation.
Therefore, plane will take 85 seconds to travel 12.75 miles.
