Answer:
d. $33,641.50
Explanation:
In this question, we use the PMT formula which is shown in the spreadsheet.
The NPER represents the time period.
Given that,
Present value = $375,000
Future value = $0
Rate of interest = 7.5%
NPER = 25 years
The formula is shown below:
= -PMT(Rate;NPER;PV;FV;type)
So, after solving this, the answer would be $33,641.50
<u>Solution and Explanation:</u>
arrival time = 24 per minute, processing time = 12 minutes, number of servers = 1 ( work for 8 hours a days)
a. arrival rate = 60 divide 24 = 2.5 customer per hour, service rate = 60 divide 12 = 5 customers per hour
therefore, the probability that the operator will be busy = 2.5 divide 5 = 0.5
thus, the percentage of idle time = 1 minus 2.5 divide 5 = 0.50
Thus, the percenatge idle time is 50%
b. the average spent by a student waiting in a line =
= 0.20 hours.
Thus, on an average a student spent 0.20 hours waiting in line.
c. the average number in waiting line = 0.5 customers
d. the probability for the given condition to happen is 0.25, 25%
