Swap the 1st and the 2nd rows inversing determinant sign
Divide the 1st row by 54
Multiply the 1st row by 33
Subtract the 1st row from the 3rd row and put the 1st row back as it was
Divide the 2nd row by 12
Multiply the 2nd row by 5
Subtract the 2nd row from the 3rd row and put the second row as it was
Multiply the main diagonal numbers
A= -(54)(12)(-35/12)(0)(0)= 0

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.
