The service-time distribution describes the probability p that the service time of the customer will be no more than t hours. if m is the mean number of customers serviced in an hour, then p=1-e^-mt. suppose a computer technical support representative can answer calls from 6 customers in an hour. what is the probability that a customer will be on hold less than 30 minutes? a. 65% c. 85% b. 75% d. 95% select the best answer from the choices provided a b c d

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
