Answer:
Explanation:
a. In a regression equation expressed as y= a + bx, how is the letter b best described?
Here, b is the slope and best described as the estimate of the cost when there's a visit of an additional customer.
b. How is the letter y in the regression equation best described?
The letter y is the observed store cost for that particular month.
c. How is the letter x in the regression equation best described?
The letter x is the observed customer visit for that particular month.
d. Based on the data derived from the regression analysis, what are the estimated costs for 370 customer-visits in a month?
The estimated cost for 370 customer visit will be:
Y = a + bx
where,
a =$1496
b = $2.08
x = 370 customer visit
Y = $1496 + ($2.08 × 370 customer visit)
= $1496 + $769.6
= $2265.6
e. What is the percent of the total variance that can be explained by the regression equation?
The percent of total variance which the regression equation explain will be:
R2 = 0.86814 or 86.814%
Answer: 2 Apple Pies.
Explanation:
As you may well know, the OPPORTUNITY COST of doing something is the gain you would have gotten if you did an alternative.
In this scenario therefore we will be simply answering that Monica would have done if she wasn't making 1 loaf of bread.
Monica takes 2 hours to bake a loaf of bread and 1 hour to bake a pie.
So what would happen if Monica had 2 hours free because she didn't make a loaf of bread?
If it takes just an hour to make an apple pie, Monica now has 2 spare hours so she will be able to make 2 Pies.
Therefore Monica's opportunity cost of making a loaf of bread is 2 Pies.

Answer: 80%
Explanation:
Statistics released by the United States affirmed what we already knew about the disproportionate distribution of wealth in the world.
One of those statistics showed that 80% of all the income in the world is being received by only a fifth of the population whilst the rest of the population being 4/5, are left to share 20% of the world's income. This level of wealth disparity is simply staggering.
