Part of the question is missing
The mean is the sum of the given data divided by the number of the data
So we will add the data first
The sum of the times = 10 + 5 + 6 + 8 + 13 + 9 + 11 = 62
The number of students = 7
The mean is

Round it to the nearest tenth, then
The mean = 8.9
The mean travel time is 8.9
One Answer: Choice C) 0 < x < 1
==================================================
Explanation:
Let's go through the answer choices one at a time.
- Choice A represents an increasing interval since the graph goes uphill as we move from left to right. The line through the points (-2, f(-2)) and (-1.5, f(-1.5)) has a positive slope. We can rule out choice A.
- Choice B is a similar story to choice A. The graph goes uphill when we move from x = -1 to x = 0, so the graph is increasing on the interval -1 < x < 0. We can rule out choice B.
- In contrast, choice C is a decreasing interval. Going from x = 0 to x = 1 has us move downhill. Choice C is the only answer.
- Choice D is false because choice C was shown to be true.
