The percent of variation is 85.1%. If you enter the numbers into a calculator and store the regression equation, it will be the r^2 value when calculated.
Answer:
It takes 5 days to process an application.
Step-by-step explanation:
We have that number of requests per month would be equal 1600
Now, the applications in hand would be:
160 + 240 = 400
They tell us that everything must be in a number of 20 business days, therefore, the number of applications in one day would be:
1600/20 = 80
Which means that the time needed to finish an application is:
400/80 = 5 days
It takes 5 days to process an application.
Answer:
Step-by-step explanation:
y = k*x This is the formula for a direct variation.
- y = 20
- x = 4 Substitute these values into the direct variation
20 = 4 * k Divide by 4
20/4 = 4k/4
k = 5
Answer: the constant of variation is 5
A "learning rate" expresses the ratio of the labor spent on the n-th item to that spent on the (n/2)-th item. That is, the 8th helicopter manufactured took days related by ...
0.8 × (days for 8th) = (days for 16th)
(days for 8th) = (days for 16th)/0.8 = 1.25×(days for 16th)
Then the days for the 4th are 1.25 times that, and the days for the 2nd are 1.25 times the days for the 4th. The days for the first helicopter will be
... 1.25⁴×106.496 days = 260 days
The appropriate choice is
... d. 260
