Question

which of the following statements is true for the situation given above?
a. the number of people attending the carnival each day ranges from 1 to 10.
b. the number of visitors on the first day of the carnival ranged from 50 to 100.
c. the number of visitors attending the carnival each day was recorded for 10 days.
d. the number of visitors at the carnival each day ranged from 30 to 100.

Explanation:

Step1: Analyze the x - axis

The x - axis is labeled "Number of Days". The values on the x - axis range from 1 to 9 (not 1 - 10 as in option A).

Step2: Analyze the y - axis on day 1

On day 1 (x = 1), the number of visitors (y - value) is around 75 (not in the range 50 - 100 as in option B).

Step3: Analyze the x - axis range

The x - axis has values from 1 to 9, which means the data is recorded for 9 days (not 10 as in option C).

Step4: Analyze the y - axis range

The minimum y - value is around 30 and the maximum y - value is around 75. But if we consider the graph's y - axis scale, the number of visitors ranges from 30 to 75 (but if we assume some mis - scale interpretation, the upper limit is close to 75 which is less than 100. However, if we consider the general trend of the graph's y - axis, the maximum value is above 70 and minimum is 30. If we assume the y - axis is mis - scaled in the problem's context, the range from 30 to 100 (option D) is the most reasonable among the given options.

Answer:

D. The number of visitors at the carnival each day ranged from 30 to 100.
