Answer and Explanation:
Using Javascript:
function mean(nums){
var array_numbers= new array(nums);
var meanofNums= array_numbers.reduce()/array_numbers.length;
Console.log(meanofNums);
}
Function Std(nums){
var OurArray= new Array(nums);
var meanOfnums= mean(nums);
var i;
for(i=0; i<=OurArray.length; i++){
OurArray[i]= OurArray[i]-meanOfnums*OurArray[i]-meanOfnums;
}
var al_stdOfnums= OurArray.reduce()/OurArray.length;
var stdOfnums= Math. sqrt(al_stdOfnums);
Console.log(stdOfnums);
}
function meanStdDev (nums){
mean(nums);
Std(nums);
}
/*From the code above, we have defined functions and used them in the last function definition meanStdDev (nums), making for code reusability. In defining the functions, we have followed the formulas for calculating mean and standard deviations and implemented in that order. Notice how we used a for loop in std(nums) function definition to iterate through the elements of the array nums, squaring each value and reassigning a new value for each element(using index value) in the array. We then added these values in array using reduce method, dividing by array length and square rooting the value using the math object method sqrt().*/

Tristen is teaching her history course. She printed off her presentation so the students could take notes. Wyatt is
teaching a science course. He wants to make sure students who do not have PowerPoint can still view the
presentation. Reed is teaching a math course online. He finds the students are very visual and wants to control the
timing per slide
Which best describes how each teacher handled their presentations?
O Tristen created handouts, Wyatt saved as a PDF, and Reed saved as a video
O Tristen created a video, Wyatt saved as a PDF, and Reed broadcasted.
O Tristen created handouts, Wyatt saved as a video, and Reed saved as a PDF.
O Tristen created a video, Wyatt broadcasted, and Reed saved as a video
Since Tristen want her students to take notes on her presentations, she should have some sort of handout.
Because Wyatt, wants to ensure that students who do not have PowerPoint can still view his presentations, converting it into a pdf is best.
Since Reed's students are very visual, converting his slides into a video will make it better for students who want to spend some time assessing some of the graphs or equations.
Thus, A is the best choice.

What types of customizations have you or would you make to your operating system, and why?
Answer:
Explanation:
I have made a couple of customizations to my OS, which is Windows 10. The first being that I activated dark mode, this feature turns the entire OS into a dark-themed color, including apps and menus. This makes using the computer for extended hours much easier on the eyes. The other very important customization I added was a hover taskbar. This allows me to add many important shortcuts to the taskbar which all appear when I hover over the taskbar. It makes my desktop much cleaner and I have quick and easy access to my most important applications.
why the internet is not policed
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

The program prompts the user for five to ten numbers all on one line, separated by spaces, calculates the average of those numbers, and displays the numbers and their average to the user.
The program uses methods to:
1) get the numbers entered by the user all on one line separated by spaces;
2) calculate the average of the numbers entered by the user; and
3) print the results.
The first method should take no arguments and return a String of numbers separated by spaces.
The second method should take a String as its only argument and return a double (the average).
The third method should take a String and a double as arguments but have no return value.
IF user input is: 20 40 60 80 100
Answer:
import java.util.Scanner;
public class AverageDemo
{
public static String getNumbers()
{
String numbers;
Scanner scn = new Scanner(System.in);
System.out.println("Enter five to ten numbers all on one line, separated by spaces: ");
numbers = scn.nextLine();
return numbers;
}
public static double calcAverage(String numbers)
{
String[] values = numbers.split(" ");
double total = 0;
for (int i = 0; i < values.length; i++)
{
total += Integer.parseInt(values[i]);
}
if (values.length == 0)
return 0.0;
else
return (total / values.length);
}
// Method definition of printResults: print the results
public static void printResults(String numbers, double average)
{
System.out.printf("\nThe average of the numbers %s is %.2f\n", numbers, average);
}
// main method
public static void main(String[] args)
{
// Call the methods
String numbers = getNumbers();
double average = calcAverage(numbers);
printResults(numbers, average);
}
}
Output:

You are in charge of installing a remote access solution for your network. You decide you need a total of four
remote access servers to service all remote clients. Because remote clients might connect to any of the four
servers, you decide that each remote access server must enforce the exact same policies. You anticipate that
the policies will change frequently.
What should you do? (Select two. Each choice is a required part of the solution.)
A. Configure network policies on the RADIUS server.
B. Make each remote access server a member of the RemoteServers group.
C. Configure the exact same network policies on each server.
D. Configure one of the remote access servers as a RADIUS server, and all other servers as RADIUS clients.
E. Use Group Policy to configure network policies in the default Domain Controllers GPO.
F. Configure each remote access server as a domain controller.
Answer: configure one of the remote access servers as a RADIUS server and all other servers as RADIUS clients

In large organizations, there is a formal business function that includes developing an information policy, planning for data, overseeing logical database design and data dictionary development, and monitoring how information systems specialists and end user groups use data. __________ is responsible for information policy, as well as for data planning, data dictionary development, and monitoring data usage in the firm.
Answer:
Data administration.
Explanation:
Data management is a type of infrastructure service that avails businesses (companies) the ability to store and manage corporate data while providing capabilities for analyzing these data.
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Thus, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.
Hence, a database management system (DBMS) is a system that enables an organization or business firm to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data.
Data administration is a strategic process that is typically responsible for establishing information policy, data planning, data dictionary development, and monitoring data usage in the firm.

Abdullah wants to send sessitive data. Abdullah wants to make sure that only ahmed can see and read this. How can abdullah protect this data, so that ahmed can only access it. By using this information make an algorithm.
Answer:
Use an encryption algorithm
Explanation:
An encryption algorithm can be used to hide the message from parties in-between or any third parties that might want to intercept the message being sent by Abudullah to Ahmed.
Encryption algorithms use cryptographic methods to encrypt or code data such that only the sender and receiver of that data have the keys to properly decode/decrypt these messages/data.
