Answer:
The correct answer is: option D
Explanation:
The degree of operating leverage (DOL) is a measure used to evaluate how a company's operating income changes after a percentage change in its sales. A company's operating leverage involves fixed costs and variable costs. It is a financial ratio that measures the sensitivity of a company’s operating income to its sales. This financial metric shows how a change in the company’s sales will affect its operating income.
There are two main formulas to calculate the DOL:
DOL= Contribution Margin/ Operating Income
or
DOL= [Qx(P-V)] / [QX(P-V)-F)
Where:
Q: the number of units
P: the price per unit
V: the variable cost per unit
F: the fixed costs
Answer:

Wants are the desire to have or own goods and services that give satisfaction. A want is a wish to possess something. The wish or desire may be fulfilled or not. Satisfying wants is through the consumption of goods and services. Consumers have an unlimited desire to have goods and services that have high utility value.
Wants differ in different people depending on their culture , age, social status, gender, and several other factors. Satisfying one need is depended on the individual's willingness and ability to pay for the goods or services that satisfy that need. Satisfying wants requires resources. Because human needs have unlimited wants, it is almost impossible to satisfy all wants with limited resources. Due to the scarcity of resources, competition arises to satisfy the many wants with the available resources.
loneliness is one of the unexpected drawbacks.

Explanation:
Even though the democratic republic of Congo is rich in natural resources while Switzerland has almost no natural resources, but Switzerland is among one of the richest countries while Congo is among the poorest.
This indicates that abundant natural resources are not the only factor required for economic growth. Other factors such as human capital, physical capital, state of technology, etc. are also necessary for economic growth. Abundant natural resources cannot be efficiently utilized without these factors.
Even if a country is not rich in natural resources but possesses these factors, it can still have high economic growth.
Answer:
Portfolio SD = 0.18439 or 18.439%
Explanation:
The standard deviation of a stock or a portfolio is the measure of the total risk contained in the stock or portfolio. Risk can be defined as the volatility of the stock returns. To calculate the standard deviation of a two stock portfolio, we use the attached formula.
If the weight of stock x is 40%, the weight of stock y will be 1 - 40% = 60%
SD = √(0.4)^2 * (0.35)^2 + (0.6)^2 * (0.15)^2 + 2 * 0.4 * 0.6 * 0.25 * 0.35 * 0.15
SD = 0.18439 or 18.439%
