Answer:
6.34 %
Explanation:
For computing the coupon rate, first we have to determine the PMT by using the PMT formula that is shown on the attachment
Given that,
Present value = $939.02
Future value = $1,000
Rate of interest = 7.15% ÷ 2 = 3.58%
NPER = 11 years × 2 = 22 years
The formula is shown below:
= PMT(Rate;NPER;-PV;FV;type)
The present value come in negative
So, after solving this, the PMT is $31.70
It is semi annually
Now the annual PMT is
= $31.70 × 2
= $63.40
So, the coupon rate equals to
= $63.40 ÷ $1,000
= 6.34 %
Answer:
the average number of customers awaiting repairs = 0.30
the system utilization = 42
the amount of time that the repairman is not out on a call is = 4.64 hours
the probability of two or more customers in the system = 0.1764
Explanation:
Given that :
Repair time, including travel time = mean of 1.6 hours per call.
Requests for copier repairs = mean rate of 2.1 per eight-hour day
i.e mean rate R = 2.1/day
Time = 8 hours
thus; mean rate μ = 8 hours/ 1.6 hours = 5
(a)
Let the average number of customers awaiting repairs be :
the average number of customers awaiting repairs = 0.30
(b) Determine system utilization.
The system utilization is determined as follows:
(c) The amount of time during an eight-hour day that the repairman is not out on a call is calculated as :
Percentage of Idle time = 1 -
Percentage of Idle time = 1 - 0.42
Percentage of Idle time = 0.58
However during an 8 hour day; The amount of time that the repairman is not out on a call is = 0.58 × 8 = 4.64 hours
(d)
the probability of two or more customers in the system by assuming Poisson Distribution is:
P(N ≥ 2) = 1 - (P₀+ P₁)
where;
P₀ = 0.58
P₁ = 0.58 × 0.42 = 0.2436
P(N ≥ 2) = 1 - ( 0.58 + 0.2436)
P(N ≥ 2) = 1 - 0.8236
P(N ≥ 2) = 0.1764
Thus; the probability of two or more customers in the system is 0.1764
Overdraft is a facility provided by bank to make expenses more than that of the balance present in the account of customers. This facility is provided to certain specified customers with high credibility.
Given
Balance is $202.86
Note: Payments will be recognized in descending order because it is the policy of bank to record the highest transaction first.
Payments made are :
$113.92
$80.73
$35.24
$16.89
<h3>Calculations</h3>Therefore Shakira will be allowed to overdraw from the account as the amount of overdraft is less than $50.
Elaborating further, When we deduct the payments from the balance in descending order we reach on a conclusion that there will be 2 overdrafts made because after deducting $113.92 and $80.73 from the balance amount of $202.86 there will be 2 payments pending amounting $35.24 and $16.89 from the left balance of $ 8.21.
Therefore the correct option will be OPTION B i.e. 2 overdrafts.
