Answer: B. The data represent a sample since the data are a subset of units.
Step-by-step explanation:
- A population is the largest group of entire observations that can be made during a study.
- A sample is a finite subset of the population that represents the entire population.
Here,
Population = Participants for the study were those who used a popular social networking Web site.
Since the entire data for the "persons used a popular social networking Web site" is not possible.
There have been taken a sample of them.
∴ Correct answer is B. The data represent a sample since the data are a subset of units.

Answer:
Step-by-step explanation:
If the engine torque y (in foot-pounds) of one model of car is given by y=−3.75x^2+23.2x+38.8
The engine speed is at maximum if dy/dx = 0
dy/dx = -2(3.75)x+23.2
dy/dx = -7.5x + 23.2
since dy/dx = 0
0 = -7.5x + 23.2
7.5x = 23.2
x = 23.2/7.5
x = 3.093
Hence the maximum torque is 3.09 rev/min
