2 / 15 = 30 / x.....2 inches to 15 miles = 30 inches to x miles
could also be :
15 /2 = x/30...15 miles to 2 inches = x miles to 30 inches
either way, u will get the same answer
You need to divide 30 miles by 5 hours,so your average speed is going to be 6 miles an hour

Step-by-step explanation:
Answer:
The correct answer is D. It is not true that cluster sampling uses randomly selected clusters and samples everyone within each cluster.
Step-by-step explanation:
Cluster sampling is a method of collecting samples and statistical data, by means of which a certain group formed by people, things, events, etc., is taken as a sample, which are not considered individually but as part of a whole, which is in turn a proportional representation of the universality of samples available in the field.
Now, since this type of sampling allows to embrace large groups of sample units, data are not always obtained from all the components of the cluster, but from those necessary to be able to quantify the desired statistics.
