C) 3.07 x 10 to the negative 4
Hi there!
We can begin by setting the two expressions equal to solve for t:
2t - 1 = 5t
Subtract 2t from both sides:
-1 = 3t
Divide both sides by 3:
t = -1/3
Plug in this value of t into x(t) and y(t):
x(-1/3) = 2(-1/3) - 1 = -2/3 - 1 = -5/3
y(-1/3) = 5(-1/3) = -5/3
Thus:
(-5/3, -5/3) are the corresponding coordinates.
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.
