Answer:
The beta of stock T is 1.82
Explanation:
The portfolio beta is made up of the weighted average of the individual stock betas in the portfolio.
The formula for portfolio beta is,
Portfolio beta = wA * beta of A + wB * beta of B + ... + wX * beta of X
The weight of stock T in the portfolio is = 1 - (0.11 + 0.56) = 0.33 or 33%
Let beta of Stock T be x. The beta of Stock T is:
1.47 = 0.11 * 0.84 + 0.56 * 1.39 + 0.33 * x
1.47 = 0.0924 + 0.7784 + 0.33x
1.47 - 0.0924 - 0.7784 = 0.33x
0.5992 / 0.33 = x
x = 1.815 rounded off to 1.82
Even when competitive firms are unable to calculate marginal revenue product directly, the pressures of competition in the labor market will push wage rates toward the marginal revenue product of labor.
By comparing the marginal revenue<span> and </span>marginal<span> cost from each unit produced, a </span>firm<span> in a </span>competitive<span> market can </span>determine<span> the </span>profit<span>-maximizing level of production.</span>
What Is an Export? By definition, exports are a function of international trade whereby goods produced in one country are shipped to another country for future sale or trade. Exports are a crucial component of a country's economy, as the sale of such goods adds to the producing nation's gross output.
Answer:
c. 50
Explanation:
Fixed-order-interval inventory model also known as fixed reorder cycle inventory model is used to manage supply of raw material to a business based on demand of the product. Review of inventory is done by inventory analyst at fixed intervals and of inventory level is above a predetermined reorder level, nothing is done.
If however stock is at or below set reorder level raw material is purchased and is based on the formula- Maximum level - Current level.
In the scenario above we use the following formula
Standard deviation of demand over the review and lead-time period(SD)=Square root of { (Lead time+ Number of days between review)* (Standard deviation of daily demand)^2}
SD= √ {(10+15)*(10)^2}
SD= √ (25* 100)
SD= √2,500
SD= 50
