Answer:
67.29%
Explanation:
The computation of the contribution margin ratio is shown below:
Contribution margin ratio = (Contribution margin) ÷ (Sales) × 100
where,
Contribution margin equals to
= Total sales - variable cost
= $214,000 - $70,000
= $144,000
So, the Contribution margin ratio is
= ($144,000) ÷ ($214,000) × 100
= 67.29%
Based on the students who passed, the probability that a random student gets an A in Statistics or Psychology or both is 0.226.
The probability that a random student did not get an A in Psychology is 0.84.
<h3>What are the probabilities of getting an A in psychology?</h3>
In order to find out the probability that a person got an A in either Statistics, Psychology, or both, the formula is:
= Probability of A in Psychology + Probability of A in Statistics - ( Probability of A in Psychology and Statistics)
= (80 / 500) + (82 / 500) - ( 49 / 500)
= 0.16 + 0.164 - 0.098
= 0.226
The probability of not getting an A in Psychology is:
= 1 - Probability of A in Psychology
= 1 - (80 / 500)
= 0.84

Answer:
C) it does not change GDP
Explanation:
The selling of existing homes does not affect the GDP since they were built in previous years. Only the sale of newly built homes increase the GDP.
Only the services provided by real estate agents, appraisers, lawyers, etc. related to the sale of existing homes are included in the GDP.
Answer:
<em>All other variables held constant, investments paying simple interest have to pay significantly higher interest rates to earn the same amount of interest as an account earning compound interest.</em><u><em> </em></u><u>TRUE. </u>
This is a true statement because compound interest is based on the previous balance in addition to the interest earnings on the balance. It therefore accrues on a higher balance than simple interest which builds on the same amount of principal throughout. Simple interest would therefore need a higher rate to bridge this gap.
<em>Everything else held constant, an account that earns compound interest will grow more quickly than an otherwise identical account that earns simple interest.</em> <u>TRUE. </u>
An account earning compound interest would increase faster than an identical one using simple interest because compound interest is based on an accrued balance whilst simple interest does not change the balance it is based on.
<em>All other factors being equal, both the simple interest and the compound interest methods will accrue the same amount of earned interest by the end of the first year.</em> <u>TRUE. </u>
At the end of the first year, an assuming yearly compounding, both simple and compound interest will yield the same result because they would be based on the same principal amount.
