What method of the Math object can be used to return the largest value from the values that are passed to it?

miss Akunina [59]

Answer:

the Math.max() method

Explanation:

The java.lang.* package contains all the essential components needed for a JAVA program which involves numbers and all the operations done on the numericals.

The java.lang.math class contains all the methods needed to perform mathematical operations on numerical values.

All the methods in the question are discussed below with examples.

Math.max() method

java.lang.Math.max(double/ int/ float a, double/ int/ float b)

This method returns the highest value from among the parameters passed to it.

The syntax for the above is

Numbers can be integers, float and double or long. The return type is the same as the parameters.

Two values to be compared are passed as arguments and the higher value of them is returned.

This function also accepts negative integers as parameters.

Math.max(-9, -2);

Gives -2 as the output.

Math.max(0.34, 0.45)

Gives 0.45 as the output.

Math.ceil() method

java.lang.Math.ceil(double/ int/ float a)

This method returns the nearest greater whole number for the given number.

Integer parameter returns an integer number.

Math.ceil(7);

Gives 7 as the output.

Decimal number will return the nearest higher integer.

Math.ceil(8.7);

Gives 9.0 as the output.

Math.ceil(-0.34)

Gives -0 as the output.

Math.pow() method

java.lang.Math.pow(double/ float/ int a, double/ float/ int b)

The above method returns the result of a raise to the power of b.

The first parameter is the base while the second parameter forms the exponent.

Math.pow( 2.3, 4.5 );

This calculates (2.3)^4.5.

Gives 42.44‬ as the output.

Math.pow( 2, 3 );

This calculates the value of 2^3.

Gives 8 as the output.

Math.abs() method

java.lang.Math.abs(double a)

This method returns non-negative value of the numerical parameter passed to it. Absolute of a number does not changes its value but changes the sign of a negative number. It returns the positive or negation of the negative input number.

Math.abs(-0.1234)

Gives 0.1234 as the output.

Math.abs(12.34)

Gives 12.34 as the output.

These methods require java.lang.Math to be imported in the program.

Write a program that reads 20 integers from the user into an array and uses a function arrayMinimum that accepts an integer arra

neonofarm [45]

Answer:

#include <iostream>

using namespace std;

int arrayMinimum(int myArray[], int myArraySize) {

int small = myArray[0];

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

if(myArray[i]<small){

small = myArray[i];

}

return small;

}

int main(){

int myArray[20];

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

cin>>myArray[i];

}

cout<<"The smallest is: "<<arrayMinimum (myArray,20);

return 0;

}

Explanation:

This solution is provided in c++

#include <iostream>

using namespace std;

This line defines the arrayMinimum function

int arrayMinimum(int myArray[], int myArraySize) {

This initializes the smallest of the array element to the first

int small = myArray[0];

This iterates through the array

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

This if condition checks for the smallest

if(myArray[i]<small){

The smallest is assigned to the small variable

small = myArray[i];

}

This returns the smallest

return small;

}

The main method begins here

int main(){

This declares an array of 20 elements

int myArray[20];

The following iteration allows user input into the array

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

cin>>myArray[i];

}

This calls the method and returns the minimum

cout<<"The smallest is: "<<arrayMinimum (myArray,20);

return 0;

}

Assuming outFile is a file stream object and number is a variable, which statement writes the contents of number to the file ass

professor190 [17]

Answer:

Its outfile<<number.

However, before this we need to write

outfile.open("xyz.txt", ios;;out)

outfile<<number

And this code will do what is required in the question. This is going to write the number's content to the xyz.txt file which is the file associated with the outfile.

And remember this is in C++. And C++ is a imperative oriented programming language. Undoubtedly, Python and R are fully object oriented programming languages.

Explanation:

The answer is self explanatory.

Is the following statement true or false?

Alchen [17]

Answer:

The following statement is True.

Explanation:

Because when we are applying the pair t-test then, take differences of that pair and then treat it as an individual samples. Formula for the test is a statistic and in this case, it is also same as formula in the one-sample of t statistics.

Therefore, it will be an equivalent to the one-sample t-test.
