Response:
Total individuals Favorable = 5850
Detailed explanation:
Total Individuals = 8000
Company Anticipates those who will respond Favorably = 6000
Percentage Error = = 150
Total individuals Favorable = Company Anticipates those who will respond Favorably minus Percent Error
Total individuals Favorable = 6000-150
Total individuals Favorable = 5850.
Response:
Option B.
Step-by-step breakdown:
The general equation for the best fit line is
where a indicates the slope and b the y-intercept.
Utilizing a graphing calculator yields a=-4.54762 and b=43.7143. Hence, the equation for the best fit line can be represented as
Here,
Note: Alternatively, you can apply the following formula to compute the slope.
Accordingly, the correct choice is B.
