Uppose that a bank has two tellers receiving customers from a single line. Assume that the amount of time a customer is served by a teller is memoryless, and that, on average, the first teller takes 5 minutes per customer, and the second teller takes 6 minutes per customer. When you arrive, there are 2 customers being served (one by each teller) and three customers in front of you in line. (a) What is the expected amount of time you will wait before being offered service by a teller?

(b) What is the expected amount of time you will be at the bank?

i need the options

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
