Answer:

4845 different combinations of programs

Explanation:

A combination is an arrangement where order is NOT important.

In this case, the number of different combinations of assignments of the programs is,

_^{20}C_{4} = \frac{20!}{4!(20-4)!}

_^{20}C_{4} = \frac{20.19.18.17.16!}{4.3.2.1(16)!}

_^{20}C_{4} = \frac{20.19.18.17}{4.3.2.1}

_^{20}C_{4} = \frac{116280}{24}=4845

Hope this helps!

Find and fix the error in the if-else statement. import java.util.Scanner;
salantis [7]

Answer:

Hi there Rumanruxi! The error is in the if statement "if(userNum = 2)".

Explanation:

The if statement in this Java code is assigning userNum the value of 2 instead of comparing it with the value of 2. For equals comparison we need to write two equals "==" in the statement as: "if (userNum == 2)". This will return true if userNum is 2 otherwise it will return false.

In a linux script, the line ____ is important because it identifies the file as a script.
igor_vitrenko [27]
The closest line to that would be the first line:


#!/bin/bash

echo "Hello World!"


BTW, the "#!" is referred to as a she-bang. When those are the first characters executed, the (requires an absolute path) program that follows is launched, and the rest of this file is given to it as data. To run this like a program, the execute permissions need to be set ( chmod 0755 script.sh ).
