I think the answer is neither
Since we want to estimate the percentage of adults in the town who belong to a gym. We should take a random sample from the town itself because a store’s adult customers, or their friends, or first 20 customers every day for one week, or adults at the local park might not represent better sample for survey.
Therefore, Take a random sample of adults in the town, and ask each person whether he or she belongs to a gym. Calculate the percentage of the total who say “yes.”
Hence, option D describes a method that will help the marketing department accurately estimate this percentage.
3x+x= 180°(straight angle)
4x= 180°
x= 180/4
x= 45°
