Answer:
C. The principal randomly selects homeroom classes and surveys each student in the chosen classes.
Step-by-step explanation:
Middle school is 6-8th. Surveying only the eighth-grade students won't give a representative sample of the whole school only the eighth-graders. Option A is incorrect.
Surveying only the students in detention represents a very small amount of students compared to the school, therefore it is not a representative sample. Option B is incorrect.
Yet again, the students in the math club is a small amount of students compared to the school. It does not represent the entire, or majority of the population. Option D is incorrect.
Picking students from homeroom classes and surveying each will give a wider variation of opinions from each grade and therefore a representative sample. Option C is the correct answer.

Tyler ran <em>0.06 miles farther </em>than Elena
Step-by-step explanation:
From the graph we can find the distance ran by Tyler in 10 minutes is approximately 1.24 miles
Given the equation for Elena's distances and times is
y=8.5x, where x is the distance in miles and y is the time in minutes, we can know the value of x when y = 10 minutes
miles
With this numbers at hand, we can infer Tyler ran 1.24 - 1.18 = 0.06 miles farther than Elena
