Equation A : x + z = 6
Equation B : 2x + 3z = 1

Possible step used in eliminating in  z-term.

Multiply equation A by -3.

-3(x +z) = -3(6)
-3x - 3z = -18

-3x - 3z = -18
 <u>2x + 3z =   1</u>
-x           = -17
<u>÷ -1           ÷ -1
</u>x             = 17

The service time distribution describes the probability P that the service time of the customer will be no more than T hours. If
Molodets [167]

Answer: option d.

Step-by-step explanation:

You have the following formul given in the problem:

p=1-e^{-mt}

You know that:

The number of  customers serviced in an hour by the technical support representative is 6 costumbers, therefore:

m=6

As the problem asked for the probability that  a costumber will be on hold less than 30 minutes, we know that:

t=0.5

Substitute the values above into the formula.

Then, you obtain:

p=1-e^{-(6)(0.5)}=0.95 or 95%
