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:

We have a service rate of:

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:

Then, the probability that a student arriving at the ATM will have to wait is 67%.
Answer:
3.C
Step-by-step explanation:
the line is going down so the slope is negative and the y intercept is 4. also to find the slope fine a point for example 1,1 so either go up or down the the next point like 0,4 so it up 3 and over one which is 3/1 which is just 3.
4.c
for the slope you go up 5 over 1 for and for the y intercept will always gave 0 and something beside it but sense it us 0 then you just done have one also you can just plot the points and make a line as well.
Step-by-step explanation:
do you want to find r?
so do 4252.50/ (18000*54)
Answer:
y(t)= 10 (2)^t
Step-by-step explanation:
If t is the number of years given then the expected number can be found by
y(t)= 10 (2)^t
where t takes the value 0,1,2,3, and so on.
Putting t= 0
y(t)= 10 (2)^t
y(0)= 10 (2)^0
y(0)= 10 For the start the number of deer are 10.
Putting t= 1
y(t)= 10 (2)^t
y(1)= 10 (2)^1
y(1)= 20 After 1 year it has doubled to 20
Putting t= 2
y(t)= 10 (2)^t
y(2)= 10 (2)^2
y(2)= 40 After 2 years it has again doubled to 40
Putting t= 3
y(t)= 10 (2)^t
y(3)= 10 (2)^3
y(3)= 80 After 3 years it has again doubled to 80
