Answer:
option (B) 0.012634
Explanation:
Data provided in the question:
Expected return Probability
16.5% 80%
-11.6% 20%
Now,
Mean return = ∑( Probability × Expected return )
= ( 0.8 × 16.5% ) + ( 0.2 × (-11.6%) )
= 13.2% - 2.32%
= 10.88%
Thus,
Variance = ∑(Probability × [ Expected return - Mean return ]² )
= 0.8 × ( 16.5% - 10.88% )² + 0.2 × ( -11.6% - 10.88% )²
= 0.8 × ( 5.62% )² + 0.2 × (-22.48%)²
= 0.8 × 0.0562² + 0.2 × 0.2248²
= 0.002526752 + 0.010107008
= 0.01263376 ≈ 0.012634
Hence,
The correct answer is option (B) 0.012634
Answer:
FV= $137,440.62
Explanation:
Giving the following information:
Bob makes his first $ 800 deposit into an IRA earning 7.4 % compounded annually on his 24th birthday and his last $ 800 deposit on his 39th birthday (16 equal deposits in all). With no additional deposits, the money in the IRA continues to earn 7.4 % interest compounded annually until Iob retirees on his 65th birthday.
First, 16 years:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
FV= {800*[(1.074^16)-1]}/0,074= $23,067.90
Next 25 years.
FV= PV*(1+i)^n
FV= 23,067.90*(1.074)^25= $137,440.62

You can spend money on things you need first instead of the things you want. Most people spend their pay on things that they want rather than getting something they need this leads to financial problems. Another way is to put at least $20 in the bank every paycheck. This way if something bad happens and you need to pay for it then you have the extra money in your bank. Daily spending can be a bad thing because you are constantly spending and never saving money, and life is full of surprises so you need to save money as well for preparation.
Hope this helped. Have a great day!
Answer:
Firm should hire the 4th worker as MR > MC.
Explanation:
Here, we are comparing the marginal cost of hiring 4th worker with the revenue generated by the 4th worker.
Marginal cost of hiring 4th worker:
= Total cost with 4 workers - Total cost with 3 workers
= $4,600 - $4,000
= $600
Total revenue generated by the 4th worker:
= Number of units produced by 4th worker × Price of each unit
= 50 × $15
= $750
Therefore, the firm should hire the 4th worker as the marginal revenue of 4th worker is greater than its marginal cost.
