Answer:
A. Selection of the appropriate causal variable Y is important
Explanation:
We have this function, Y = f(X).
From this function we can see that Y is dependent on X. That is, it is a function of X. Y is not a causal variable. A causal variable is a variable that is able to influence the variable of interest. From this question Y is the variable of interest. It is the dependent variable. The independent variable is X and it is the causal variable.
Therefore the incorrect one is Selection of the appropriate causal variable Y is important
Answer:
. $45
Explanation:
Let X be the amount of equal charges per customer.
Therefore,
X-12+X-25+X-40+X=100.
4X-77=100
4X=177
X=44.25
Approximately $45
Idk who that is either lol
Answer:
c. $1,300 gain
Explanation:
In this scenario, Susan recognized a $1,300 gain on this sale. This is because Susan originally purchased the stock for a total price of $6,000. When she sold the stock, she sold it for a higher price than what she originally paid for it therefore recognizing a gain. To calculate this gain we simply subtract her initial purchase price from her selling price of the stock which would give us a $1,300 gain.
$7,300 - $6,000 = $1,300
