In systematic sampling, individuals are selected at regular intervals from the sampling frame.
<h3>How to explain the sampling?</h3>
Stratified sampling- In this method, the population is first divided into subgroups (or strata) who all share a similar characteristic
<u>Clustered sampling.</u>- a clustered sample, subgroups of the population are used as the sampling unit, rather than individuals. The population is divided into subgroups, known as clusters, which are randomly selected to be included in the study
<u>Simple random sampling. </u>-In this case each individual is chosen entirely by chance and each member of the population has an equal chance, or probability, of being selected.
Quota sampling--This method of sampling is often used by market researchers. Interviewers are given a quota of subjects of a specified type to attempt to recruit.

Answer:
26.02
Step-by-step explanation:
the absolute value of (-11.74-14.28) which is 26.02
Answer:
The equation line is y + 3x = -10.
Step-by-step explanation:
In this question, first we have to find the slope of the equation:
The formula which we use to find the slope is:
slope = m = (y2-y1)/(x2-x1)
m = (8 + 1) / (-6 + 3)
m = 9 / (-3)
m = -3.
Now, put the value of slope and the first points (-3, -1). You can use any of the given points:
y - y1 = m(x - x1)
y + 1 = -3(x + 3)
y + 1 = -3x - 9
y + 3x = -10
This is the eqution line.
You can check if this line is true or not by putting the other points in this equation which will give the same points like,
y + 3(-6) = -10
y - 18 = -10
y = 8
So, we get the same old points (-6, 8) which we have given.
