Answer:
the probability that exactly 30 of the 500 calculators IS 0.0495
Explanation:
Given data:
number of calculators n = 500,
percentage of defected calculators p = 0.05
From Normal approximation method;
Therefore probability is
P(X= 30) = P(29.5< X< 30.5) ( from continuous correction)
![ =P[\frac{(29.5-25)}{4.87}] < \frac{(X-mean)}{s} < \frac{(30.5-25)}{4.87} =P(0.92](https://tex.z-dn.net/?f=%0A%3DP%5B%5Cfrac%7B%2829.5-25%29%7D%7B4.87%7D%5D%20%3C%20%5Cfrac%7B%28X-mean%29%7D%7Bs%7D%20%3C%20%5Cfrac%7B%2830.5-25%29%7D%7B4.87%7D%0A%3C%2Fp%3E%3Cp%3E%0A%3DP%280.92%3CZ%3C%201.13%29%0A)
=0.0495 (from standard table of Z )

Answer:
$115,035
Explanation:
Calculation for what the The net present value of the project is closest to:
First step is to calculate the Present value of annual cash flows
Using this formula
Present value of annual cash flows = Annual Cash Flow * PVA of * (11%, 4 years)
Let plug in the formula
Present value of annual cash flows = $ 137,000 * 3.1024456895909
Present value of annual cash flows =$425,035
Now let calculate the net present value of the project
Net present value of the project =$425,035-$ 310,000
Net present value of the project=$115,035
Therefore the The net present value of the project is closest to: $115,035
Answer:
$160
Explanation:
Calculation to determine How much does the investor gain or lose
Investor gain =[($20-$18.2)*100 Shares]- ($0.2*100 shares)
Investor gain=($1.8*100 shares)-($0.2*100 shares)
Investor gain=$180-$20
Investor gain=$160
Therefore The amount that the investor gain is $160
