Customers in a Bank In the Ames International Campus Bank (open 24h every day) 5 customers arrive on average during an hour. Answer the following questions. First write down the problem in terms of some random variables and write down what distribution assumptions you make about these random variables. (a) What is the probability that during an hour no customer arrives? (b) What is the probability that during an hour, 7 or more customers arrive? (c) What is the probability that there's more than 30 minutes between the 2nd and 3rd customer of the day? (d) What is the probability that you have to wait less than an hour for seven customers to arrive? (e) How many minutes do you expect to wait until the 12th customer arrives? (f) How many minutes do you expect to wait on average between arrivals?

Answer and Step-by-step explanation:

The answer is attached below

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
