Question

Question: The graph shows the relationship between the number of members in a club and the number of years after the club began. Based on the trend shown in

this data, predict the year in which the club will have no members.
Answer Choices:
A: 1 year
B: 3 years
C: 6 years
D: 8 years

Answer 1

D: 8 years

Explanation:

To do this, just make the line of best fit.

For this problem just try to find a line that has the same amount of data points on both sides and goes through the middle.

In this situation 2 ½ of the data points will be on each side.

On average since all data points have more than 1 student from 1 to 5 years, A and B are obviously incorrect.

C is incorrect because on average the number of students decreases by around 10 to 15 every year, so the club will have between 20 and 15 students in 6 years.

Therefore D can only be correct.
