How the equation y=7.5x + 50 shows the slope and the y-intercept
iris [78.8K]

Answer:

slope:7.5, y-intercept:50

Step-by-step explanation:

The basic equation for slope is y=kx+b

In this equation, k stands for slope and b stands for y-intercept.

So in y=7.5x+50, k is 7.5 and b is 50 which equal to slope is 7.5 and y-intercept is 50

Which of the following is not true about cluster sampling?
Aloiza [94]

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.
