Answer:

The probability that a student arriving at the ATM will have to wait is 67%.

Step-by-step explanation:

This can be solved using the queueing theory models.

We have a mean rate of arrival of:

$\lambda=1/3\,min^{-1}$

We have a service rate of:

$\mu=1/2\,min^{-1}$

The probability that a student arriving at the ATM will have to wait is equal to 1 minus the probability of having 0 students in the ATM (idle ATM).

Then, the probability that a student arriving at the ATM will have to wait is equal to the utilization rate of the ATM.

The last can be calculated as:

$P_{n>0}=\rho=\dfrac{\lambda}{\mu}=\dfrac{1/3}{1/2}=\dfrac{2}{3}=0.67$

Then, the probability that a student arriving at the ATM will have to wait is 67%.

I’m not positive but I’m thinking you are supposed to draw the door and window or color them in and each small square counts as a foot so like 7 of the squares is 7 feet so after you color in the door and window it will show what part needs to be painted

Answer:

22.05

Step-by-step explanation:

21/2 has 5 halves

10.5 divided by 5= 2.1

2.1= 1/2 2.1 x 10 = 21

2.1 / 2 = 1.05

21 + 1.05= 22.05
