Explanation:

Inside the action performed method, pass the strings in text box.
check if the value has been modified then do the relevant conversions inside the conditional statement.
When the user clears, it will not do to the inch conversion.

From the set ( 5 , 7 , 9 , 11 , 13 make the inequality w - 4 < 8 true

Ksenya-84 [330]

Answer:

Explanation:

One group of students did an experiment to study the movement of ocean water. The steps of the experiment are listed below.

Fill a rectangular baking glass dish with water.

Place a plastic bag with ice in the water near the left edge of the dish.

Place a lighted lamp near the left edge of the dish so that its light falls directly on the plastic bag.

Put a few drops of ink in the water.

The student did not observe any circulation of ink in the water as expected because the experiment had a flaw. Which of these statements best describes the flaw in the experiment? (2 points)

Not enough ink was added.

Not enough water was taken.

The dish was too small for the experiment.

The lamp and the ice bag were at the same place.

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(" ");

}

}

Your friend really likes talking about owls. Write a function owl_count that takes a block of text and counts how many words the

andriy [413]

Text = “ I really like owls. Did you know that an owls eyes are more than twice as big as the eyes of other birds of comparable weight? And that when an owl partially closes its eyes during the day, it is just blocking out light? Sometimes I wish I could be an owl.

word = ‘owl’
texts = text.lower()
owlist = list(texts.split())
count = text.count(word)
num = [owlist, count] #num has no meaning just random var
print(num)

Alter in anyway you want so that you can succeed. ✌

Insert a formula that references the appropriate worksheets in cell a3 on the offensive totals worksheet to calculate total pass

Mnenie [13.5K]

In excel spreadsheets, you need to consider specifying relationships between the information you have stored in your spreadsheets when creating formulas. The elements that will help you understand using spreadsheet are the constants, operators, references and functions. This will enable you to use the formulas, without hassle in spreadsheets.
