Answer:
The command to create a compressed archive (archive1.tar.gz) is

Explanation:
The explanation for the above command is
The general command to create a compressed archive is
tar -czvf name-of-archive.tar.gz /path/to/directory-or-files
Here, the terms are as follows:
-c : Creates an archive
-z : Compress the archive with gzip.
-v : This is known as verbose. This is an optional command and it displays the progress on terminal command. Without this the progress is not displayed on terminal command.
-f : Allows to specify the file name of the archive.
Here, if we want to archive multiple files, we provide the command the names of multiple files or directories of the files also can be used.
So, the command 
creates a compressed archive - archive1.tar.gz of files test1, test2 and test3.
Using the knowledge in computational language in mathlab it is possible to write a code that while loop that continues to increment uservalue by 5 as long as uservalue is less than 0.
<h3>Writting the code:</h3>
<em>function </em><em>userValue </em><em>= IncreaseValue(userValue)</em>
<em>while(userValue<0)</em>
<em>userValue = </em><em>userValue</em><em>+5;</em>
<em>end</em>
<em>end</em>
<h3>How to run a code in MATLAB?</h3>
To run: If inside the Editor window: on the toolbar choose the Run icon; or in the Debug menu choose the Run option; or press F5. If the file is saved in memory, just type its name in the command window.

Answer:
Explanation:
There are various questions that you can ask in this scenario, such as
What grading policies are being implemented?
How many student grades are being calculated by the program?
What is the requirements for a student to pass?
All of these questions would allow you to get an idea of how extensive the code may be and its complexity. Once you know this you would look at the code revolving around actually looping through the data and doing the necessary calculations. You can then determine how to manipulate the code and make it much more efficient.
You would also need to know how the student data is being saved, which will help determine if it is the best data structure for saving this type of data or if it can be replaced in order to maintain the data secure while increasing the speed of the program. Mainly since this information needs to be continuously used from the data structure.
