Answer:
Cluster
Step-by-step explanation:
According to the Question,
- Given this, Daimler−Chrysler randomly selects 100 service centers during a certain week and surveys all customers visiting the service centers.
This is a Cluster type of Sampling.
- Cluster sampling is a type of sampling method in which the population under study is divided into different groups known as clusters before simple random samples are selected from each population cluster. The analysis of such a population is carried out based on the sampled clusters.
- This method is adopted when a researcher does not have access to the whole population under research.
Advantages of cluster sampling
- The research method only needs fewer resources.
- The sample under review is feasible.
Note: Cluster sampling is not as accurate as simple or stratified random sampling.
First find the slope by calculating rise (change in x) over run (change in y).
(4/5)-0/0-(-5)
(4/5)/5=0.16
The y intercept is 4/5. We know this because y interceot is the value of y when x is 0.
Then plug this into y=mx+b where m is slope andb is y intercept.
Final answer: y=0.16x+0.8 or y= 4/25x+ 4/5
Answer:
C.

.
Step-by-step explanation:
Let r represent the cost of one packet of radish seeds and let t represent the cost of one packet of tomato seeds.
Roman spent $62.75
This implies that,

Roman bought 32 packets of seeds and one packet of radish seeds costs
$ 1.75.
One packet of tomato seeds costs $ 2.50.
This implies that,

Using guess and check means we substitute into the given equation.
