Answer:

D. 12.20%

Explanation:

Stock X Weight = 0.60

Stock Y Weight = 0.40

sdX = 10%

sdY = 20%

Portfolio Variance = w2X*sd2(X) + w2X*sd2(Y) + 2*(wX)*(wY)*Cov(X, Y)

Where: wX and wY are portfolio weights, sd2(X) and sd2(Y) are variances and

Cov(X, Y) is the covariance

Correlation = 0.5

Cov(X, Y) = Correlation * sd(X) * sd(Y)

= 0.50 * 0.10 * 0.20

= 0.01

Portfolio Variance = 0.60^2 * 0.10^2 + 0.40^2 * 0.20^2 + 2 * 0.60 * 0.40 * 0.01

Portfolio Variance = 0.0036 + 0.0064 + 0.0048

Portfolio Variance = 0.0148

sd(P) = √Variance = 0.121655 = 12.20%

max2010maxim [7]

Answer:

a, The PPF intersect the Y-axis at 1000 units of luxury goods

   The PPF intersect the X-axis at 500 units of necessity good

    It means that when the society produces zero units of necessity, it can          produce 1000 units of luxury goods and if they use all resources to produce necessity, they can produce 500 units only

b. The economy can produce at a point inside the curve IF (1) There is underutilized of the available resources. (2) There is inefficiency in the use of resources  

c. I will want to produce more necessity than luxury. The decision on which point the society will want to be depend on the type of economic system being practiced by my society, if it is free market, the price system will determine it and for a socialist system, the government decides.

d. If I am a dictator, I will make decrees as to the economic direction I want for the society and where the product distribution is left to the free market, the price system decides.

Explanation:

The production possibility frontier is a graph that shows the trade-off between two commodities which a country can be assumed to produce. An economy can operate on the PPF in which case it is using its resources to the fullest. It can operate inside the curve which means under-utilization of resources or inefficiency in resources utilization. A country cannot operate outside the curve except there is technological progress or economic growth.

Vlad1618 [11]

Answer:

Residual income= $36,000

Explanation:

Residual income is the income that is generated in excess of the minimum required rate of return, which in this case is 10%. Any income above 10% return is considered as residual income. In this case the investment is 1,800,000 and 10% of that is 180,000 (0.1*1,800,000). So any income made above $180,000 will be residual income. In order to find the residual income we subtract the minimum income required from the actual income.

In this case the minimum income required is 180,000 and the actual operating income is 216,000 so residual income=

216,000-180,000= $36,000
