the percent of markup is 56% (55.62 to be exact)
Answer:
The population mean is 5 volts
Step-by-step explanation:
Output voltage is assumed to be normally distributed, with standard deviation 0.25 Volts
s=0.25
n = 8
Sample mean = 
Since n < 30 and population standard deviation is unknown
So, we will use t test
Formula : 
t=-1.69
Refer the t table for p value
Degree of freedom = n-1 = 8-1 = 7
So,
P value >α
So, We are failed to reject null hypothesis
Hence The population mean is 5 volts
For the Jet one the answer should be 450 but its not on there
Answer:
$6,283.56
Step-by-step explanation:
The net present value is the present value of after tax cash flows from an investment to the amount invested in a project.
Net present value can be calculated using a financial calculator
Cash flow in year zero = -$290,000
Cash flow each year from year one to three = 0
Cash flow each year from year four to twelve = $64,000.
I = 9%
NPV = $6,283.56
To find the NPV using a financial calacutor:
1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.
2. After inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.
3. Press compute
I hope my answer helps you
