Answer:
4.53%
Explanation:
Data provided in the question:
Expected return = ∑ (Return × probability)
Thus,
Expected return = (0.06 × 22) + (0.92 × 13) + (0.02 × (-15))
= 12.98%
Now,
Probability Return Probability × (Return-Expected Return)²
0.06 22 0.06 × (22% - 12.98%)² = 4.8816
0.92 13 0.92 × (13% - 12.98%)² = 0.000368
0.02 -15 0.02 × (-15% - 12.98%)² = 5.657608
========================================================
Total = 20.5396%
Standard deviation = 
= √(20.5396)
= 4.53%

Answer: d. Products the consumer could have bought instead of cigarettes.
Opportunity cost refers to the loss benefits from the choices a person would have made if he or she had not made a particular choice.
Opportunity cost is also known as alternate cost.
In this question, had the consumer would have spent on other products if he had not bought cigarettes. Hence these products represent the opportunity cost of cigarettes.
Answer:
orange juice 0.80 dollar
Bagel 1 dollar
coffe 0.60 dollar
Explanation:
We construct the equation system:

We subtract one from another to get an expression without C:
1.5A+1.2B+C - (A+B+C) = 3 - 2.40
0.5A + 0.2B = 0.6
Then, we solve in the first part to express B as an expression of A
considering the coffe is worth half of the new cost of A
C = 1.5A / 2 = 0.75A
A + B + C = 2.40
A + B + 0.75A = 2.40
B = 2.40 - 1.75A
And now we replace in the other expression to get A:
0.5A + 0.2(2.40 - 1.75A) = 0.6
0.5A - 0.35A + 0.48 = 0.60
0.15A = 0.12
A = 0.12/0.15 = 0.8
Now we solve for C:
C = 0.75A = 0.6
Last, for B:
A + B + C = 2.40
0.8 + B + 0.6 = 2.40
B = 2.40 - 0.8 - 0.6 = 1
Answer:
Accounting and economics both involve plenty of number-crunching. But accounting is a profession devoted to recording, analyzing, and reporting income and expenses, while economics is a branch of the social sciences that is concerned with the production, consumption, and transfer of resources.
