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:

(1)
For <em>r</em> = + 1 compute the standard deviation of portfolio as follows:

Thus, for correlation 1 the standard deviation of portfolio is 0.433.
(2)
For <em>r</em> = 0 compute the standard deviation of portfolio as follows:

Thus, for correlation 0 the standard deviation of portfolio is 0.3191.
(3)
For <em>r</em> = -1 compute the standard deviation of portfolio as follows:

Thus, for correlation -1 the standard deviation of portfolio is 0.127.
Answer:
a) Determine which type of cars will be sold at the efficient allocation.
All cars would be sold in a Pareto efficient allocation.
In a Pareto efficient market, resources are all allocated in the most efficient possible way. This is the reason why this is just a theoretical concept that does not necessarily apply in real life.
b) Determine which type of cars will be sold at the market equilibrium.
Since consumers are only willing to pay up to $1,620 for a used car, only medium quality and low quality cars will be sold. The price of high quality used cars is higher than the equilibrium price.
Explanation:
the most a buyer would be willing to pay for a used car is ($1,800 x 40%) + ($1,600 x 30%) + ($1,400 x 30%) = $720 + $480 + $420 = $1,620
the answer to this question is 4.70%
C: They charge extremely high interest rates.
Answer:
The amount of total current assets that will be reported on the budgeted balance sheet is $40,000.
Explanation:
Total current assets
= Cash + Accounts receivable + Finished goods inventory + Raw materials inventory
= $4,000 + $16,000 + $12,000 + $8,000
= $40,000
Therefore, The amount of total current assets that will be reported on the budgeted balance sheet is $40,000.
