To configure the computer in the lobby to use the corporate proxy server, you will need to follow these steps:

Settings > Networks&Internet > Proxy > Manual Proxy Setup > Address & proxy > save

A proxy server is a device or router that acts as a connection point between users and the internet.

Proxy Server settings would be the same for both Wifi and Ethernet connections, explaining about the configuration in Windows Operating System.

Open the internet browser on the laptop and go to the settings or preferences page. The exact location of the proxy settings will vary depending on the browser you are using.

In the settings or preferences page, look for the "Proxy" or "Network" section.

In the proxy settings, select the option to use a proxy server.

Enter the address of the corporate proxy server in the "Server" or "Address" field.

Enter the port number "9000" in the "Port" field.

Save the changes and close the settings or preferences page.

Test the proxy server configuration by attempting to access a website. If the configuration is correct, the laptop should be able to access the internet through the proxy server.

You could use recursion to write java method for computing fibonacci numbers. Though it will be inefficient for n > about 50, it will work.

public static int fibonacci(int n) {

if (n < 0) { return -1; }

if (n < 2) { return n; }

else { return fibonacci(n-1)+fibonacci(n-2); }

}

Hope this helps.

The current term of a Fibonacci series is derived by adding the two previous terms of its sequence; and the first two terms are 0 and 1.

The code segment (without comments) that completes the program is as follows:

int T1 = 0, T2 = 1, cT;

   if (n < 0){

       return -1;     }

   for (int i = 2; i <= n; i++) {

       cT = T1 + T2;

       T1 = T2;

       T2 = cT;     }

   return T2;

With comments (to explain each line)

/*This declares the first term (T1), the second term (T2) and the current term (CT).

T1 and T2 are also initialized to 0 and 1, respectively

*/

int T1 = 0, T2 = 1, cT;

//This returns -1, if n is negative

   if (n < 0){         return -1;    

}

//The following iterates through n

   for (int i = 2; i <= n; i++) {

//This calculates cT

       cT = T1 + T2;

//This passes T2 to T1

       T1 = T2;

//This passes cT to T2

       T2 = cT;

   }

//This returns the required term of the Fibonacci series

   return T2;

At the end of the program, the nth term of the series would be returned to the main method for output.

A string, for example, is a data type that is used to classify text and an integer is a data type used to classify whole numbers.

Explanation:

Assuming you mean ping from device with SIM card to another host (no mater what host), the ping will change. Ping changes even on the same device because network speed and performance of all the nodes on the route changes continuously. However, if two of your devices (phone & router) are configured differently (use different routing under the hood), then it will also affect the ping.

In case I am looking for a specific book in a library, the way in which I would try to find it would be through consulting the library guide, or through inspection of the different books of the specific sector with which the book I'm looking for is listed, or by asking the library staff to help me with my search.

Using a combination method to determine how many ways can 18 people be divided into programming teams of 3 members, the number of programming teams can be arranged in 816 ways.

In mathematical model, a combination is a mathematical approach for calculating the number of potential arrangements in a set of things without taking the order arrangement of the items is into consideration.

It can be expressed by using the formula;

[tex]\mathbf{ _nC_r = \dfrac{n !}{ r!(n-r)! } }[/tex]

where:

[tex] \mathbf{ _nC_r = \dfrac{18!}{ 3!(18-3)! } }[/tex]

[tex]\mathbf{ _nC_r = \dfrac{18!}{ 3!(15)! } }[/tex]

[tex] \mathbf{ _nC_r = \dfrac{18 \times \: 17 \times \: 16 \times 15!}{ 3!(15)! } }[/tex]

Answer:

Ex: If the input is:

5 50 60 140 200 75 100

the output is:

50 60 75

The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75.

For coding simplicity, follow every output value by a space, including the last one.

The following is written in Java and uses a for loop to add 10 elements to the ArrayList since the first element is manually added as 1. Then it calculates each element by multiplying the previous element (saved in count) by 2. The program works perfectly and without bugs. A test output can be seen in the attached image below.

import java.util.ArrayList;

class Brainly {

   public static void main(String[] args) {

       ArrayList<Integer> numberList = new ArrayList<>();

       numberList.add(0, 1);

Answer:

The program in C++ is as follows:

#include <iostream>

using namespace std;

double average(double s1, double s2, double s3, double s4, double s5){

   double avg = (s1 + s2 + s3 + s4 + s5)/5;

   return avg;}

char lGrade(double score){

   char grade;

   if(score>= 90 && score <= 100){ grade ='A'; }

   else if(score>= 80 && score <= 89){ grade ='B'; }

   else if(score>= 70 && score <= 79){ grade ='C'; }

   else if(score>= 60 && score <= 69){ grade ='D'; }

   else if(score < 60){ grade ='F'; }

   return grade;}

int main(){

   double s1,s2,s3,s4,s5;

   cin>>s1>>s2>>s3>>s4>>s5;

   double avg = average(s1,s2,s3,s4,s5);

   cout<<s1<<" "<<lGrade(s1)<<endl;

   cout<<s2<<" "<<lGrade(s2)<<endl;

   cout<<s3<<" "<<lGrade(s3)<<endl;

   cout<<s4<<" "<<lGrade(s4)<<endl;

   cout<<s5<<" "<<lGrade(s5)<<endl;

   cout<<avg<<" "<<lGrade(avg)<<endl;

   return 0;}

Explanation:

The three functions to include in the program are not stated; so, I used the following functions in the program

1. The main function

2. average function

3. Letter grade function

The average function begins here

double average(double s1, double s2, double s3, double s4, double s5){

This calculates the average

   double avg = (s1 + s2 + s3 + s4 + s5)/5;

This returns the calculated average

   return avg;}

The letter grade function begins here

char lGrade(double score){

This declares the grade

   char grade;

If score is between 90 and 100 (inclusive), grade is A

   if(score>= 90 && score <= 100){ grade ='A'; }

If score is between 00 and 89 (inclusive), grade is B

   else if(score>= 80 && score <= 89){ grade ='B'; }

If score is between 70 and 79 (inclusive), grade is C

   else if(score>= 70 && score <= 79){ grade ='C'; }

If score is between 60 and 69 (inclusive), grade is D

   else if(score>= 60 && score <= 69){ grade ='D'; }

If score is less than 60, grade is F

   else if(score < 60){ grade ='F'; }

This returns the calculated grade

   return grade;}

The main begins here

int main(){

This declares the 5 scores

   double s1,s2,s3,s4,s5;

This gets input for the 5 scores

   cin>>s1>>s2>>s3>>s4>>s5;

This calls the average function for average

   double avg = average(s1,s2,s3,s4,s5);

This calls the letter grade function for the 5 scores

   cout<<s1<<" "<<lGrade(s1)<<endl;

   cout<<s2<<" "<<lGrade(s2)<<endl;

   cout<<s3<<" "<<lGrade(s3)<<endl;

   cout<<s4<<" "<<lGrade(s4)<<endl;

   cout<<s5<<" "<<lGrade(s5)<<endl;

This calls the average function for the average

   cout<<avg<<" "<<lGrade(avg)<<endl;

The following code is written in Javascript and is a function called primes that takes in a single parameter as an int variable named n. An array is created and looped through checking which one is prime. If So it, changes the value to true, otherwise it changes it to false. Then it creates another array that loops through the boolArray and grabs the actual numberical value of all the prime numbers. A test case for n=150 is created and the output can be seen in the image below highlighted in red.

function primes(n) {

   //Boolean Array to check which numbers from 1 to n are prime

   const boolArr = new Array(n + 1);

   boolArr.fill(true);

   boolArr[0] = boolArr[1] = false;

   for (let i = 2; i <= Math.sqrt(n); i++) {

      for (let j = 2; i * j <= n; j++) {

          boolArr[i * j] = false;

      }

   }

   //New Array for Only the Prime Numbers

   const primeNums = new Array();

  for (let x = 0; x <= boolArr.length; x++) {

       if (boolArr[x] === true) {

           primeNums.push(x);

       }

  }

  return primeNums;

}

alert(primes(150));
