You are adding more features to a linear regression model and hope they will improve your model. If you add an important feature, the model may result in.
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
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.describe at least five ways in which information technology can help studying subjects other than computing

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 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.
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.The coding system that has just two characters is called:

What is the most vulnerable information that should be protected to prevent unauthorized access to your online files and records?
Answer:
Your user ID and password.
Explanation:
The user Id and password must be protected because when it is exposed to a third party then they can get access to information, data, to things they are not supposed to.
The user Id and password is provided as an authentication measure for one to be able to gain access to a computer system, network or files. It is what grants access to online files and record as it is the case here. It has to be protected for the sake of privacy.

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.
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

4. Word Separator:Write a program that accepts as input a sentence in which all of thewords are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example the string “StopAndSmellTheRoses.” would be converted to “Stop and smell the roses.”
*python coding
sent = input("")
count = 0
new_sent = ""
for i in sent:
if count == 0:
new_sent += i
count += 1
else:
if i.isupper():
new_sent += " "+i.lower()
else:
new_sent += i
print(new_sent)
The above code works if the user enters the sentence.
def func(sentence):
count = 0
new_sent = ""
for i in sentence:
if count == 0:
new_sent += i
count += 1
else:
if i.isupper():
new_sent += " " + i.lower()
else:
new_sent += i
return new_sent
print(func("StopAndSmellTheRoses."))
The above code works if the sentence is entered via a function.

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
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.
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.
