Suppose a computer technical support representative can answer calls from 8 customers in an hour. what is the probability that a customer will be on hold less than 15 minutes?

Option d

Step-by-step explanation:

We need 2 fundamental data to solve this problem.

1.- Average number of clients attended in 1 hour.

2.- Time in which it is expected that a client will be attended.

They tell us that the average number of clients served in an hour is m = 8

They tell us to calculate the probability that the client will be seen in less than 15 minutes.

But the time t in the formula is given in hours.

Therefore we must write 15 minutes according to hours.

We know that .

So:

.

Now we substitute in the formula and to find P.

Therefore,

Priya's way is correct to  solve the equation.

Step-by-step explanation:

Given:

Jada and Priya are trying to solve the equation,

For Jada way of calculation :

I think we should multiply each side by 32 because that is the reciprocal of 23.

Also Reciprocal of 23 is

We have

...Which is INCORRECT

For Priya way of calculation :

I think we should add -23 to each side because that is the opposite of 23.

We have

plus minus= minus , (+ - = - )

23 will get cancelled and she will get "x"

...Which is CORRECT

Hence Priya's way is correct to  solve the equation.

The other Person strategy to solve will be:

I think we should subtract 23 to each side because that is the opposite of 23.

We have

...Which is also CORRECT.

Therefore,

Priya's way is correct to  solve the equation.
