Since the cylinder has a radius of 10m and a height of 8m, then the exact volume would be 800^m3
The correct option among the other answer choices would be as follows: D.
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.
P(Face card) =16/52 = 4/13
P(Spade) = 13/52 =1/4
P(Face ∪ Spade) = 4/13 + 1/4 = 29/52 = 0.557
Simple; you want to divide 3 and 8.
3 / 8 = 0.375
And there's your answer! Remember that a fraction is just a fancy division problem! :)
