Answer:
<h2>It is Random sampling.</h2>
Step-by-step explanation:
There are total 5 types of sampling.
- Random Sampling: In this kind of sampling, elements are randomly chosen from a particular population. Every elements of the population carries the same probability in this case.
- Systematic Sampling: Every k-Th element is taken for this kind of sampling.
- Convenience Sampling: Here samples are chosen as per the accessibility.
- Cluster Sampling: First the whole population is divided in some groups or cluster, then some groups are randomly selected.
- Stratified Sampling: The whole population is being divided into groups as per some characteristic. Then from each group, one sample is to be chosen either randomly or using some other process.
Since, in the given question the students are chosen randomly, Random sampling is being used here.

I hope this helps:)
Answer: n=5
Step-by-step explanation: You are solving for ‘n’ so you would want to get ‘n’ by itself on one side of the equation. The easiest way to do this would be to divide both sides by 3, which would make ‘3n’ turn to ‘n’ and 15 into 5.
-5/8 or -8/5 so that is tgd answer yeah
Answer:
Step-by-step explanation:
(a) When two quantities vary inversely, their product is the constant of variation:
d = k/c → cd = k
For d=17 and c=2, k = 2·17 = 34
Then the equation can be written as ...
cd = 34 . . . or . . . d = 34/c
__
(b) d = 34/68 = 1/2 . . . . . put c=68 into the above equation to find d
For c=68, d=1/2.
