Answer: Cluster sampling.
Step-by-step explanation:
- Cluster sampling is a sampling technique in statistics in which the researcher splits the entire population into different groups called clusters.
- After that he randomly select a sample from the clusters from the population and survey all elements of sampled clusters.
- Researcher performs his analysis on data from the sampled clusters.
In the given situation Greyhound Lines randomly selects 90 buses during a certain week and surveys all passengers on the buses.
Here, week= Cluster
Buses = Elements
Therefore , the type of sampling is used = Cluster sampling.
He would make $1239.75
divide 4 in 2,204
multiply by 2.25
The answer is B
Not sure but sorry if wrong, I can explain how I got it if you want
Answer:
5
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2+b^2 = c^2
where a and b are the legs and c is the hypotenuse
QR^2 + 12^2 = 13^2
QR^2 +144 =169
QR^2 = 169-144
QR^2 =25
Take the square root of each side
QR = sqrt(25)
QR =5
