Answer:
Defragmenting the hard drive identifies areas on the hard drive that need to be fixed? <u>The answer is FALSE</u>.
Explanation:
When certain information are being removed from the hard drive, tiny gaps are usually being created which can be filled when we store new data. As the new data is being saved on our computer, they occupy those available spaces. When the gaps are not large enough for the files, they get stored in other available areas. This makes the entire files to be scattered and the process is called fragmentation.
In defragmentation, the system is being asked to put all these scattered information in one area of the file, so that it could be easier for one to access them faster. It does not identify areas on the hard drive that needs to be fixed.
Check Disk (chkdsk.exe), rather helps with scanning through the entire hard drive, to find and fix errors.
Answer:
E. Cluster
Explanation:
Cluster sampling is a type of sampling method in which the population under study is divided into different groups known as clusters before simple random samples are selected from each population clusters. The analysis of such population is carried out based on the sampled clusters.
This method is adopted when a researcher does not have access to the whole population under research.
Advantages of cluster sampling.
The research method only needs fewer resources.
The sample under review is feasible.
Note: Cluster sampling is not as accurate as simple or stratified random sampling.
Answer:
The correct answer is: in all decision making.
Explanation:
Economic analysis is used in all walks of life, in decision making. It is not only relevant for policymaking or in business or for students. Rather, it is used in day to day life as well.
Almost all the decision we make is based on cost-benefit analysis. It used by households and individuals for utility maximization. It is used by businesses for profit maximization and is used by policy makers for welfare maximization.
