( 10 +7) - x = 12 
17 - x = 12
- x = 12 - 17
- x = - 5 
x = 5 

17 - 5 = 12

Suppose a computer technical support representative can answer calls from 8 customers in an hour. What is the probability that a
Ganezh [65]

Answer:

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 1\ hour = 60 minutes.

So:

15\ minutes[\frac{1\ hour}{60\ minutes}] = 0.25\ hours.

Now we substitute in the formula m = 8 and t = 0.25 to find P.

P = 1 -e^{-mt}\\\\P = 1- e^{-(8)(0.25)}\\\\P = 1 - e^{-2}\\\\P = 0.8646\\\\P= 86\%

PLS HELP<br> If f(x) = x2 -1, what is the equation for f–1(x)?
Anon25 [30]

We have a function,

f(x)=x^2-1

and we are asked to find its inverse function.

An inverse function essentially gets you the original value that was dropped into a function.

For example,

If I put 5 into f(x) I will get 24. Now If I take 24 and put it into the inverse function I have to get number 5 back.

The way to determine the inverse function swap the x and the f(x), then solve for f(x),

x=f(x)^2-1

f(x)^2=x+1

f(x)=\pm\sqrt{x+1}

Of course the notation demands that the obtained function be called,

f^{-1}(x)=\pm\sqrt{x+1}

Hope this helps :)
