spin [16.1K]

Answer:

(a) E(X) = 3

(b) Var(X) = 12.1067

Explanation:

(a) E[X]

E[X]T = E[X]T=A + E[X]T=B + E[X]T=C

= (2.6 + 3 + 3.4)/3

= 2.6 (1/3) + 3(1/3) + 3.4(1/3)

= 2.6/3 + 1 + 3.4/3

= 3

(b) Var (X) = E[X²]−(E[X])²

Recall that if Y ∼ Pois(λ), then E[Y 2] = λ+λ2. This implies that

E[X²] = [(2.6 + 2.6²) + (3 + 3²) + (3.4 + 3.4²)]/3

= (9.36 + 12 + 14.96)/3

= 36.32/3

= 12.1067

Var(X) = E[X²]−(E[X])²

= 12 - 3²

= 12.1067 - 9

= 3.1067

Exercise 11-1 Compute the Return on Investment (ROI) [LO11-1] Alyeska Services Company, a division of a major oil company, provi

vaieri [72.5K]

Answer:

1. Margin = 0.32 or 32%

2. Turnover = $19,000,000 or Operating Asset Turnover = 0.52 or 52%

3. Return on Investment = 0.17 or 17%

Explanation:

Firstly, list out the parameters we were given:

Sales = $19,000,000, Net Operating Income = $6,100,000,

Average Operating Assets = $36,500,000

1. Operating Margin = Net Operating Income / Sales

Operating Margin = 6,100,000 ÷ 19,000,000 = 0.32

Operating Margin = 0.32 (to 2 decimal places)

Operating Margin = 32%

2. Turnover refers to sales or revenue made during a particular period. In which case turnover is $19,000,000

However, if the turnover referred to is the Operating Asset Turnover, that is calculated below:

Operating Asset Turnover = Sales / Average Operating Assets

Operating Asset Turnover = 19,000,000 ÷ 36,500,000

Operating Asset Turnover = 0.52 (to 2 decimal places)

Operating Asset Turnover = 52%

3. Return on Investment (ROI) = Net Operating Income / Average Operating Assets

Return on Investment (ROI) = 6,100,000 ÷ 36,500,000

Return on Investment (ROI) = 0.17 (to 2 decimal places)

Return on Investment (ROI) = 17%

Suppose the dollar appreciates relative to foreign currencies. If U.S. firms have domestic content below 100%, the harm to domes

inn [45]

Answer:

The correct answer is: If U.S. firms have domestic content below 100%, the harm to domestic firms is less than the harm if U.S. producers had domestic content of 100%.

Explanation:

This strength of the dollar, which is reflected in exchange rates, has negative and positive implications at the same time for any economy.

What benefits one sector damages the purchasing power of another.

If it is good for those who receive remittances, it is bad for those who want to travel or do business abroad.

Businesses and governments also have to deal with a phenomenon that affects all aspects of the economy.

Importing oil or gas, repaying debt or contracting services abroad can cost more or less depending on exchange rates.

In general terms, that a currency depreciates against the dollar if it has a very intensive international trade with the United States, as is the case in Mexico, causes its economy to be more competitive and drives growth.

This is because American consumers can compare cheaper products made in Mexico.

So in terms of growth, this is a positive effect of the depreciation of a currency and the strength of the dollar.

The increases in interest rates made by the Federal Reserve, the body in charge of dictating the course of monetary policy in the United States, have led to a progressive general strengthening of the dollar against all currencies.

When the US central bank cuts interest rates, it encourages banks to lend more and put more money in the hands of citizens and businesses. And the opposite happens when, as now, the rates rise. Banks lend less and the dollar appreciates.
