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.

Find the nth term of this quadratic sequence. <br> 4,,9,16,25,36
Oksanka [162]
4, 9, 16, 25, and 36 are all squares of 2, 3, 4, 5, and 6 respectively.
Since the numbers being squared are increasing by 1 each time, you can figure that the sequence is n². Thus the nth term will be n².

To solve Lance’s equation, 2(x + 10) = 60, first
solniwko [45]
Divide both sides by 2
subtract 10 from both sides
2(x + 10) = 60
x + 10 = 60/2
x + 10 = 30
x = 30 - 10
x =20

subtract 20 from both sides
divide both sides by 2
2x + 20 = 60
2x = 60 - 20
2x = 40
x = 40/2
x = 20
