Answer: 9.45%

Explanation:

To solve this question, we need to know the weights of securities A and B and this will be:

Weight of A = STD of B / (STD of A + STD of B)

= 40% / (70% + 40%)

= 40% / 110%

= 0.4/1.1

= 0.3636

Weight of security A = 0.3636

Weight of security B = 1 - 0.3636 = 0.6364

Then, the rate of return of risk free portfolio will be:

= (Return of A × Weight of A) + (Return of B × Weight of B)

= (12% × 0.3636) + (8% × 0.6364)

= 0.043632 + 0.050912

= 0.094544

= 9.45%

Johnny is a sophomore in college and has a 1.5 cumulative grade point average (GPA). Johnny's cumulative GPA will fall even furt
Debora [2.8K]

Answer: B

Explanation:

With the options given, Johnny can only perform worse if he performs worse than his cumulative GPA and also if he performed less than he ever performed before. The last option about Johnny's performing worse than last semester might not necessarily have an effect on his GPA. A cumulative GPA is the total GPA Johnny has gotten since he started school. The last semester might be one of his best semesters and probably had a good result so getting a result slightly lower than his last semester might not necessarily mean there will be a reduction in his cumulative GPA. So option B is correct.

In the long run, the competitive firm's supply curve is the a. entire marginal-cost curve. b. portion of the marginal-cost curve
Mars2501 [29]

The long run will see the supply curve of a completive firm changing to the b. portion of the marginal-cost curve that lies above the average-total-cost curve.

<h3>What is the long-run supply curve in a perfect competition?</h3>

In a perfect competition, a company will only produce goods and services at a level where the marginal cost curve is above the average total cost in the long run.

This means that the supply curve will be the marginal cost curve but only the portion of this curve that is above the long-run average total cost curve.

The reason for this is that in the long-run., all the costs in a perfectly competitive firm are considered variable and so they can afford to avoid supply mishaps in the short term.

In conclusion, option B is correct.

Bogdan [553]

Answer:

d. it causes profits to be understated when prices are rising and allows a company to dodge taxes.

Explanation:

The LIFO method should not be permitted to determine the net income as in this case the profits would be understated at the time when price is increased due to this it permits the company to dodge taxes as the inventory consumed in the production process also the high inventory value would be involved in the cost of sales that represent the high cost, this result in lower profits and taxes

Hence, the option d is correct

C(x) = 0.06x^2 - 6x + 218

Its a quadratic function , minima would occur at vertex.

x is no. of digital cameras

x = -b/2a = -(-6/2*0.06) = 50 cameras

Minimum marginal cost : C(50) = 0.06(50)^2 - 6*50 + 218 = $ 68
