what would be the result of running these two lines of code

MatroZZZ [7]

Answer:

Jog

Explanation:

The variable options is a list containing 5 string values

options = ["ski", "surf", "jog", "bike", "hike"]

Indexing in python starts from 0 ; hence the index values of the list values are :

0 - ski

1 - surf

2 - jog

3 - bike

4 - hike

The statement ;

print(options[2]) means print the string at index 2 in the list named options

The string at index 2 is jog ;

Hence, the string jog is printed.

Nila has created a report, and now she would like to a create table of contents. Nila has reviewed her report and decides to add

Alenkinab [10]

Answer:

The answer is "heading"

Explanation:

Headings, which appear into your document must be marked simply, objectively and correctly because it shows the final report structure and enable to easy access with specific information.

It also promotes to read the document. So, its consistency is ensured in the headings.
In sort documents, it can't require any heading, but it Nila created a report, in which she requires heading and then she update the content of the tables, and other choices can't be described in the given scenario, that's why it is correct

Write the definition of the function inputArray that prompts the user to input 20 numbers and stores the numbers into alpha. Wri

Alina [70]

Answer:

In Java:

public static int[] inputArray(){

Scanner input = new Scanner(System.in);

int[] alpha = new int[20];

for(int i = 0;i<20;i++){

alpha[i] = input.nextInt();

}

return alpha;}

public static int[] doubleArray(int [] alpha){

int[] beta = new int[20];

for(int i = 0;i<20;i++){

beta[i] = 2 * alpha[i];

}

return beta;

}

public static int[] copyAlphaBeta(int [] alpha, int [] beta){

int [] AlphaBeta = new int[10];

for(int i = 0;i<5;i++){

AlphaBeta[i] = alpha[i];

}

int count = 5;

for(int i = 15;i<20;i++){

AlphaBeta[count] = beta[i];

count++;

}

return AlphaBeta;

}

public static void printArray(int [] alpha){

for(int i = 0;i<20;i++){

System.out.print(alpha[i]+" ");

if((i+1)%15 == 0){

System.out.println(" ");

}

Explanation:

The inputArray is defined here

public static int[] inputArray(){

Scanner input = new Scanner(System.in);

This declares alpha array of 20 elements

int[] alpha = new int[20];

The following iteration gets input from the user into the array

for(int i = 0;i<20;i++){

alpha[i] = input.nextInt();

}

This returns the alpha array

return alpha;}

The doubleArray is defined here. It takes the alpha array as its input parameter

public static int[] doubleArray(int [] alpha){

This declares beta of 20 integers

int[] beta = new int[20];

This populates beta by 2 * alpha[i]

for(int i = 0;i<20;i++){

beta[i] = 2 * alpha[i];

}

This returns the alpha array

return beta;}

The copyAlphaBeta array is defines here

public static int[] copyAlphaBeta(int [] alpha, int [] beta){

This declares AlphaBeta as 10 elements

int [] AlphaBeta = new int[10];

This populates the first 5 elements of AlphaBeta with the first 5 of alpha

for(int i = 0;i<5;i++){

AlphaBeta[i] = alpha[i];

}

int count = 5;

This populates the last 5 elements of AlphaBeta with the last 5 of beta

for(int i = 15;i<20;i++){

AlphaBeta[count] = beta[i];

count++;

}

This returns the AlphaBeta array

return AlphaBeta;

}

The printArray is defined here. It takes the alpha array as its input parameter

public static void printArray(int [] alpha){

This iterates through alpha array

for(int i = 0;i<20;i++){

This prints each element of the array

System.out.print(alpha[i]+" ");

A new line is started after the 15th element

if((i+1)%15 == 0){

System.out.println(" ");

}

}
