In order for it to be divisible by 5 AND be an even number, it must also be divisible by 2. So you are looking for two-digit numbers greater than 34 and divisible by 10:
C = {40, 50, 60, 70, 80, 90}
(a) 
(b) 
(c) 
Solution:
To write each of the given expression in the form 
:
(a) 
Using exponential rule: 
(b) 
Divide numerator and denominator by the common factor 2, we get
Using exponential rule:
(c) 
Divide numerator and denominator by the common factor 7, we get
Using exponential rule:
The inverse function is y(x)=4x+3

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.
