1. Increase in R-square
2. Decrease in R-square
A) Only 1 is correct
B) Only 2 is correct
C) Either 1 or 2
D) None of these

Answers

Answer 1

Answer:

The answer is "Option A".

Explanation:

Add extra functionality, otherwise, it increases the R-square value, which is defined in the following points:      

To incorporate essential elements, R-square is explicitly promoted. It Increases the R-square value, which is an additional feature. It removes the features, which provide the value of the reduce R-square. After incorporating the additional features is used as the model, which is R-square, which is never reduced.

Write a function named power that accepts two parameters containing integer values (x and n, in that order) and recursively calculates and returns the value of x to the nth power.

Answers

Answer:

Following are the code to the given question:

int power(int x, int n)//defining a method power that accepts two integer parameters

{

if (n == 0)//defining if block to check n equal to 0

{

return 1; //return value 1

}

else//defining else block

{

x = x * power(x, --n); //use x variable to call method recursively

}

return x; //return x value

}

Explanation:

In the above-given code, a method power is defined that accepts two integer variable in its parameter, in the method a conditional statement is used which can be defined as follows:

In the if block, it checks "n" value, which is equal to 0. if the condition is true it will return value 1.In the else block, an integer variable x is defined that calls the method recursively and return x value.

9.2.2: Output formatting: Printing a maximum number of digits. Write a single statement that prints outsideTemperature with 4 digits. End with newline. Sample output with input 103.45632: 103.5

Answers

Answer:

The single print statement that does the required in python is:

print("%.4g" % outsideTemperature)

Explanation:

The full program is as follows:

The first line prompts user for input

outsideTemperature = float(input("Outside Temperature: "))

To print significant figures, we make use of g formats. And this is implemented as follows:

print("%.4g" % outsideTemperature)

The above prints 4 significant digits of outsideTemperature

For other significant figures, simply change the 4 to another number

Write a program that contains three methods:

Method max (int x, int y, int z) returns the maximum value of three integer values.
Method min (int X, int y, int z) returns the minimum value of three integer values.
Method average (int x, int y, int z) returns the average of three integer values.

Answers

Answer:

#include <stdio.h>//defining header file

int max (int x, int y, int z) //defining a method max that hold three parameters

{

   if(x>=y && x>=z)//defining if block that checks x is greater then y and x is greater then z

   {

       return x;//return the value x

   }

   else if(y>z)//defining else if block it check y is greater then z

   {

       return y;//return the value y

   }

   else//else block

   {

       return z;//return the value z

   }

}

int min (int x, int y, int z) //defining a method max that holds three parameters

{

if(x<=y && x<=z) //defining if block that check x value is less then equal to y and less then equal to z

{

return x;//return the value of x

}

if(y<=x && y<=z) //defining if block that check y value is less then equal to x and less then equal to z

{

return y;//return the value of y

}

if(z<=x && z<=x)//defining if block that check z value is less then equal to x  

{

return z;//return the value of z

}

return x;//return the value of z  

}

int average (int x, int y, int z) //defining average method that take three parameters

{

int avg= (x+y+z)/3;//defining integer variable avg that calculate the average

return avg;//return avg value

}

int main()//defining main method

{

   int x,y,z;//defining integer variable

   printf("Enter first value: ");//print message

   scanf("%d",&x);//input value from the user end

   printf("Enter Second value: ");//print message

   scanf("%d",&y);//input value from the user end

   printf("Enter third value: ");//print message

   scanf("%d",&z);//input value from the user end

   printf("The maximum value is: %d\n", max(x,y,z));//calling the method max

   printf("The minimum value is: %d\n", min(x,y,z));//calling the method min

   printf("The average value is: %d\n", average(x,y,z));//calling the method average

   return 0;

}

Output:

Enter first value: 45

Enter Second value: 35

Enter third value: 10

The maximum value is: 45

The minimum value is: 10

The average value is: 30

Explanation:

In the above-given code, three methods "max, min, and average" is declared that holds three integer variable "x,y, and z" as a parameter and all the method work as their respective name.

In the max method, it uses a conditional statement to find the highest number among them.In the min method, it also uses the conditional statement to find the minimum value from them.In the average method, it defined an integer variable "avg" that holds the average value of the given parameter variable.In the main method, three variable is defined that inputs the value from the user end and passes to the method and print its value.

Answer:

The output of the program is (d)

Tango Hernados Hideaway

Swing Hound Dog

Explanation:

Analyzing the given code segment

In class Dance,

A method named dance was defined with an instance of two string variables/values

which are name and song

public Dance(String name, String s)

In the main of the program,

The first line creates an instance of Dance as dance1

dance1 is initialized with the following string values: "Tango","Hernandos Hideaway"

- The first string value "Tango" will be passed into the name variable of the Dance method

- The second string value "Hernandos Hideaway" will be passed into the song variable of the Dance method

Next, another instance of Dance is initialized as dance2

dance2 is initialized with the following string values: "Swing","Hound Dog"

- The first string value "Swing" will be passed into the name variable of the Dance method

- The second string value "Hound Dog" will be passed into the song variable of the Dance method

On line 3 of the main: System.out.println(dance1.toString());

The values of dance1, which are "Tango","Hernandos Hideaway" are printed

On line 4 of the main: System.out.println(dance2.toString());

The values of dance1, which are "Swing","Hound Dog" are printed

Hence, option d answers the question

Write a function named findmax()that finds and displays the maximum values in a two dimensional array of integers. The array should be declared as a 10 row by 15 column array of integers in main()and populated with random numbers between 0 and 100.

Answers

Answer:

import java.util.*;

public class Main

{

public static void main(String[] args) {

    Random r = new Random();

    int[][] numbers = new int[10][15];

   

    for (int i=0; i<10; i++){

        for (int j=0; j<15; j++){

            numbers[i][j] = new Random().nextInt(101);

        }

    }

   

    for (int i=0; i<10; i++){

        for (int j=0; j<15; j++){

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

        }

        System.out.println();

    }

   

    findmax(numbers);

}

public static void findmax(int[][] numbers){

    int max = numbers[0][0];

   

    for (int i=0; i<10; i++){

        for (int j=0; j<15; j++){

            if(numbers[i][j] > max)

                max = numbers[i][j];

        }

    }

    System.out.println("The max is " + max);

}

}

Explanation:

*The code is in Java.

Create a function called findmax() that takes one parameter, numbers array

Inside the function:

Initialize the max as first number in the array

Create a nested for loop that iterates through the array. Inside the second for loop, check if a number is greater than the max. If it is set it as the new max

When the loop is done, print the max

Inside the main:

Initialize a 2D array called numbers

Create a nested for loop that sets the random numbers to the numbers array. Note that to generate random integers, nextInt() function in the Random class is used

Create another nested for loop that displays the content of the numbers array

Call the findmax() function passing the numbers array as a parameter

Following are the program to the given question:

Program Explanation:

Defining a variable "Sum" that holds an integer value.In the next step, a variable "t" is defined that uses the input method to input a value from the user-end.After the input value, a for loop is declared that takes the range of the t variable.Inside the loop, another variable "n" is defined that inputs value from user-end and use the "Sum" variable to add its value.Outside the loop, a print method has been used that prints the sum variable in the string with the message.  

Program:

Sum = 0#defining a variable sum that hold an integer value

t= int(input("Enter the total number you want to add: "))#defining a t variable that input value from user-end

for i in range(t):#defining a loop that add inputs values from above user-input range

   n= int(input("Enter value "+str(i+1)+": "))#defining loop that inputs n value

   Sum += n; #defining sum variable that adds user-input value

print("Sum of entered number: "+str(Sum))#using print method that print added value
