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%
The answer is D, opportunity costs.
Answer:
true
Explanation:
it was the time of the production line making it easy to make expensive things with people that are lower skilled and cheaper overall
Answer:
Answer : Average Marginal Cost, Marginal Cost = $2
The total cost per hour of the janitorial service firm = $32
Explanation:
The janitorial firm only uses labour as an input to clean offices and there are no fixed costs. This implies that the total cost is only the variable cost.
Each worker can clean 4 offices in an hour, therefore the output of each labour is 4units per office cleaned. The price/wages paid to each worker isb $8 per hour.
The total cost per hour of the janitorial service firm is $8x4 = $32 (wxq)
Now to clean one more office, the time required will be 15minuites, because each worker can clean 4 offices in an hour. To clean one more office , each worker will be paid $2($8/4)
The variable cost/total cost, average variable cost and the marginal cost of cleaning one more office will be
Variable cost =w.q = 2q
Average Variable Cost = VC/q = 2q/q = $2
sine the marginal cost also varies directly as the average marginal cost , the Marginal Cost is $2
Brazil is an example of a closed economy as it has the least amount of imports in the world
