omeli [17]

Answer:

efficiency variance

Explanation:

When standard direct labor hours differ from actual direct labor hours used, the company experienced an "efficiency varaiance". It can be used in order to analyze how effective an operation is in relation to labor, materials, machine time and other production factors.

Efficiency variance is actually the difference which exists between the theoretical amount of inputs which are needed to produce an output and the actual number of inputs which are required to manufacture the unit of output.

The expected return and standard deviation of a portfolio that is 30 percent invested in 3 Doors, Inc., and 70 percent invested

kirill115 [55]

Answer:

For correlation 1 the standard deviation of portfolio is 0.433.

For correlation 0 the standard deviation of portfolio is 0.3191.

For correlation -1 the standard deviation of portfolio is 0.127.

Explanation:

The standard deviation of a portfolio is computed using the formula:

$\sigma_{P}=\sqrt{w^{2}_{1}\sigma_{1}^{2}+w^{2}_{2}\sigma_{2}^{2}+2\times r\times w_{1}\sigma_{1}w_{2}\sigma_{2}}$

(1)

For r = + 1 compute the standard deviation of portfolio as follows:

$\sigma_{P}=\sqrt{w^{2}_{1}\sigma_{1}^{2}+w^{2}_{2}\sigma_{2}^{2}+2\times r\times w_{1}\sigma_{1}w_{2}\sigma_{2}}\\=\sqrt{(0.30^{2}\times 0.51^{2})+(0.70^{2}\times 0.40^{2})+(2\times1\times0.30\times 0.51\times0.70\times 0.40)}\\=\sqrt{0.187489}\\=0.433$

Thus, for correlation 1 the standard deviation of portfolio is 0.433.

(2)

For r = 0 compute the standard deviation of portfolio as follows:

$\sigma_{P}=\sqrt{w^{2}_{1}\sigma_{1}^{2}+w^{2}_{2}\sigma_{2}^{2}+2\times r\times w_{1}\sigma_{1}w_{2}\sigma_{2}}\\=\sqrt{(0.30^{2}\times 0.51^{2})+(0.70^{2}\times 0.40^{2})+(2\times0\times0.30\times 0.51\times0.70\times 0.40)}\\=\sqrt{0.101809}\\=0.3191$

Thus, for correlation 0 the standard deviation of portfolio is 0.3191.

(3)

For r = -1 compute the standard deviation of portfolio as follows:

$\sigma_{P}=\sqrt{w^{2}_{1}\sigma_{1}^{2}+w^{2}_{2}\sigma_{2}^{2}+2\times r\times w_{1}\sigma_{1}w_{2}\sigma_{2}}\\=\sqrt{(0.30^{2}\times 0.51^{2})+(0.70^{2}\times 0.40^{2})+(2\times-1\times0.30\times 0.51\times0.70\times 0.40)}\\=\sqrt{0.016129}\\=0.127$

Thus, for correlation -1 the standard deviation of portfolio is 0.127.

If a U.S. citizen could buy £25,000 for $100,000, the rate of exchange for the pound would be

Natalka [10]

Answer:

The rate of exchange for the £ is US$ 4

Explanation:

1. Let's check the information provided to answer the question correctly:

Amount the U.S. citizen want to buy in £ = 25,000

Amount the U.S. citizen will pay in US$ = 100,000

2. Let's calculate the rate of exchange for the British pound £, this way:

Rate of exchange = Amount in US$/Amount in £

Rate of exchange = 100,000/25,000

Rate of exchange = 4 US$ per £

We can also express the rate for the US$, this way:

Rate of exchange = Amount in £/Amount in US$

Rate of exchange =25,000/100,000

Rate of exchange = £ 0.25 per US$
