There appear to be an influential observations in these data as the mean of the leverage value is 0.75.
<h3>How to calculate the mean?</h3>
From the data points given, the influential observation is observation 8. Here, the mean of the leverage value will be:
= 3 × 0.25 = 0.75
Also, the scatter diagram indicates influential observations as it's extreme to the x values.

Answer:
$651.60
Explanation:
the worth of the bond today can be determined by calculating the present value of the bond's cash flow
Present value is the sum of discounted cash flows
Present value = cash flow / (1 + r)^n
r = interest rate
n = years
1000 / ( 1.055)^8 = $651.60
Answer:
A. the change in the value of the optimal solution.
Explanation:
- A shadow pricing is associated with each constraint of the model and is the instantaneous changes that occur in the objective model of the optimal solution that is obtained by changing the right-hand side constrained by one unit and a reduced cost is associated with each variable of the model. Also referred to as a monetary values that is assigned to the current unknowable or difficult to calculate costs.
Answer:
$62,267.91
Explanation:
first we must calculate the interest rate = 10% + 6% + (10% x 6%) = 16.6%
now we can use the present value formula:
present value = future value / (1 + rate)ⁿ
present values for:
- cash flow year 0 = $17,100
- cash flow year 3 = $46,500/1.166³ = $29,333.06
- cash flow year 4 = $12,300/1.166⁴ = $6,654.43
- cash flow year 7 = $26,900/1.166⁷ = $9,180.42
total present value = $62,267.91
