Answer: –0.0130
Explanation:
Correlation given the variance and the standard deviation of the two returns can be calculated by;
Correlation coefficient = Covariance of returns on investment A and B / (Standard deviation of return on investment A * Standard deviation of return on investment B).
Rearranging the formula, Covariance becomes;
Covariance of returns on investment A and B = Correlation coefficient * (Standard deviation of return on investment A * Standard deviation of return on investment B)
Covariance of returns on investment A and B = -0.260 * 0.25 * 0.20
Covariance of returns on investment A and B = –0.0130
Answer:
When we subsample from a population
Explanation:
A subsample is a set of data that we take from smaller group of people in order to represent the larger group.
It is really crucial for companies to get this type of subsample in order to obtain statistical data about customer's preference. This will increase the efficiency of their marketing process.
For example,
Let's say that you want to create a toy for children.
It is impossible for you to actually ask every single child in this country about the type of toys they like. In such situation, you could get a subsample from a smaller group of children (let's say you give questionnaires to 1000 children and ask them the type of toys they like.)
From the there, you could create a statistic that represent the types of toys that the children might be interested in.

Explanation:
Current liabilities are short term obligations that a company needs to pay within the current financial year. Companies use current assets to offset their current liabilities. Examples of current liabilities include accounts payable, interest payable on outstanding loans, dividends payables, and long term debts maturing within the current financial year.
A business needs to monitor its levels of current liabilities to ensure it has sufficient current assets to pay them. There are situations where a company finds it necessary to obtain a loan to finance its current liabilities. The inability to pay current debts consistently may be indicative of more profound financial challenges within the organization.
Answer:
C. increase by about 6 percent.
Explanation:
Since,
Sales = $ 120,
Original expenses = $ 65
Thus, contribution margin ratio = 
New expenses = $ 58,
Thus, contribution margin ratio = 
∵ 52 - 46 = 6,
Hence, the CMR is increased by 6%.
OPTION C is correct.
