Answer:

c. $5,000 into each company

Explanation:

Let X be the actual (random) return from each share of XX, and  Y be the actual return from each share of YY. Computing the returns from each option:

A) Investing $10,000 into XX

Given that variance = (standard deviation)²

Since XX cost $20 per share, only 500 shares can be bought.

Expected value = 500 * E(x) = 500 * 1 = 500

Variance = 500² * Var(x) = 500² * 0.5² = 62500

B) Investing $10,000 into YY

Since YY cost $50 per share, only 200 shares can be bought.

Expected value = 200 * E(y) = 200 * 2.5 = 500

Variance = 200² * Var(y) = 200² * 1² = 40000

C) Investing $5,000 into each company

Since XX cost $20 per share and YY cost $50 per share, only 250 shares of XX and 100 shares of YY can be bought.

Expected value = 250 * E(x) + 100 * E(y) = 250 * 1 + 100 * 2.5 = 500

Variance = 250² * Var(x) + 100² * Var(y) = 250² * 0.5² + 100² * 1 = 25625

Since all options have the same expected return, but option C has the lowest variance hence it is the least riskiest. So the best option is C

Suppose your firm has a marginal revenue given by the equation MR = 10 - Q where Q is the quantity produced and sold. This means
KonstantinChe [14]

Answer:

The answer is: A) When the marginal cost of producing an additional unit equals the marginal revenue from that unit.

Explanation:

In economics, we assume that a company´s main goal is to maximize its profit. In order for any company do to this, the marginal cost (MC) of producing an extra unit of production must equal the marginal revenue (MR) obtained by selling that extra unit of production.

Theoretically, in perfect market conditions, MR=MC in the equilibrium point between quantity supplied and quantity demanded. But on real world conditions elasticity of both demand and supply alter the curves.

svet-max [94.6K]

Answer:

This implies that bus is an inferior good and car is a normal good.

Explanation:

Initially, Jim's income was $5000 a year.

As his income increases to $60,000 a year, he decides to buy a car instead of using the bus.  

In other words, with the increase in income, the demand for traveling by bus is declining.  

This implies that it is an inferior good.  

The demand for the car is increasing with an increase in income.  

So, the car is a normal good.  

An inferior good can be defined as a product that shows negative elasticity. This means with an increase in income its demand declines an vice versa.

A normal good can be defined as a product that shows positive income elasticity. That is, its demand increases with rise in income and vice versa.
