4. Calculate the standard deviation for the following data set: Foundations of Technology Engineering byDesi OITEEA . . Data Set = 4, 14, 6, 2, 7, 12 217 ,​

Answers

Answer:

[tex]\sigma_x = 5.68[/tex]

Explanation:

Given

[tex]x = 4, 14, 6, 2, 7, 12 2,17[/tex]

Required

The standard deviation

First, calculate the mean

[tex]\bar x =\frac{\sum x}{n}[/tex]

So, we have:

[tex]\bar x = \frac{4+ 14+ 6+ 2+ 7+ 12 +2+17}{8}[/tex]

[tex]\bar x = \frac{64}{8}[/tex]

[tex]\bar x = 8[/tex]

The standard deviation is:

[tex]\sigma_x = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]

So, we have:

[tex]\sigma_x = \sqrt{\frac{(4 - 8)^2+ (14 - 8)^2+ (6 - 8)^2+ (2 - 8)^2+ (7 - 8)^2+ (12 - 8)^2+ (2 - 8)^2+ (17 - 8)^2}{8-1}}[/tex]

[tex]\sigma_x = \sqrt{\frac{226}{7}}[/tex]

[tex]\sigma_x = \sqrt{32.2857}[/tex]

[tex]\sigma_x = 5.68[/tex]

why the internet is not policed​

Answers

Answer:

The Internet allows people to circumvent law by committing criminal acts from areas where their activities are not illegal. Those areas will always exist, and thus new regulations will be just as ineffective as the old ones are ["Net Needs Law Enforcement, Author Says,"]. But Internet traffic is marked with IP addresses, and those addresses can be tied to specific networks with specific locations. Shouldn't it be possible to separate traffic based on the originating network and treat data coming from relatively insecure locations differently than data coming from relatively secure locations? It would be much harder for someone in a rogue nation to hack a network if he had to hack an intermediary network first. And unlike government regulation, which has zero impact in areas where these threats are likely to originate, separating traffic by location might actually work

why is computer virus called destructive program​

Answers

Answer:

A computer virus is a malicious software program loaded onto a user’s computer without the user’s knowledge and performs malicious actions.

Viruses which are the most commonly-known form of malware and potentially the most destructive. A virus can do anything from erasing the data on a computer to hijacking a computer to attack other systems, send spam, or host and share illegal content.

Explanation:

The term 'computer virus' was first formally defined by Fred Cohen in 1983. Computer viruses never occur naturally because they are always induced by people. Once created and released, however, their diffusion is not directly under human control. After entering a computer, a virus attaches itself to another program in such a way that execution of the host program triggers the action of the virus simultaneously. It can self-replicate, inserting itself onto other programs or files, infecting them in the process. Not all computer viruses are destructive though. However, most of them perform actions that are malicious in nature, such as destroying data. Some viruses wreak havoc as soon as their code is executed, while others lie dormant until a particular event (as programmed) gets initiated, that causes their code to run in the computer. Viruses spread when the software or documents they get attached to are transferred from one computer to another using a network, a disk, file sharing methods, or through infected email attachments. Some viruses use different stealth strategies to avoid their detection from anti-virus software. Some old viruses make sure that the "last modified" date of a host file stays the same when they infect the file.

16. Which of the following is true about function return statements? A) A function can hold multiple return statements, but only one return statement executes in one function call. B) A function can hold only one return statement. C) A function can hold multiple return statements, and multiple return statements can execute in one function call. D) A function can have maximum of two return statements.

Answers

Answer:

A) A function can hold multiple return statements, but only one return statement executes in one function call

Explanation:

This is because each function can only return one value, whether it be an integer, String, or other object.

However, you can have a series of if-else statements, or case statements, to return a different value depending on information (within parameters, or variables.

Excellent. So, you can have multiple return statements, but the function will only end up executing one of these return statements and return a single value.

Hope this helps!

The statement "When there are multiple return statements but one return statement should execute the 1 function call" is true.

The following information should be considered:

This can be done as every function has only a return i.e. one value. It can be an integer, string, or any other thing. The function can't hold only 1 return statement.The function can't hold many return statements that execute one function call. The function can't have the utmost 2 return statements.

Therefore, we can conclude that option A is correct.
