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.
The correct answer is perpendicular based on the concept of Parallel and Perpendicular lines from Khan Academy.
