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.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

A(n) ___________ analyzes traffic patterns and compares them to known patterns of malicious behavior.a. Intrusion prevention system b. intrusion detection system c. defense-in-depth strategy d. quantitative risk assessment
Answer:b. intrusion detection system
Explanation:
An intrusion detection system (IDS) helps to alert service administrators to detect suspicious or malicious activity by monitoring and analyzing specific patterns to network traffic. Most times, the IDS may be configured to respond to suspicious malicious traffic by blocking the cyber attacker making such IP address unable to access that particular network.
An intrusion detection system (IDS) can be either a Host Based Intrusion Detection Systems (HIDS) or a Network Based Intrusion Detection Systems (NIDS) depending on preference by the user.
It is therefore necessary for businesses who require high level of security to adopt good and effective intrusion detection systems so that the communication of information from businesses to businesses can be safeguarded and secure from cyber attacks.
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.
1. What do you think of the use of Moore’s Law to hypothesize a timeframe for the origin of life?
2. How does Moore’s Law apply to the efficiency of algorithms as we discussed in the last class?
3. Where do you think computers will be in 10 years? 100?
Answer:
1. I think it was actually a very good idea. As time goes on technology is improved, new laws and theories are proven, scientists are disproven, and efficiency of doing certain tasks evolves. Another reason would be, why not? It does not hurt to make a hypothesis or try a new approach.
1. We spend countless time exploring and digging only to possible never find what we need to exactly pin the first life forms on Earth and when they lived, why not try a new different angle. So, I think that it was a very clever and interesting to use and Moore's Law to hypothesis the origin of life.
2. Moore's law applies to the efficiency of algorithms because he came up with a way to hypothesis were in technology we should stand after a certain amount of time and how much improvements should be integrated into our computers.
2. Moore’s Law applies to the efficiency of algorithms because Moore created a exponential equation and graph of a hypothesis proven to help guide engineers on a steady path of improvement should be made to computer processors and components with in a certain amount of time.
3. In a 10 years I think computers would have only made simply yet very effective and efficient improvements. Like longer battery life, or faster speeds, but virus firewalls and defenders. But when faced with 100 years I think that would have lead to a huge drastic change to what the normal idea of a computer is. It would be so high tech to us but with the world our grandkids are living in it'll be normal to have holographic computers.
3. I think that in 10 years computers would have improved much like they have recently, smaller, more compact, faster, and longer lasting, but within 100 years we would have a another invention entirely. Computers would have changed so much more than we could have every thought.

Non-blocking code does not prevent execution from continuing while blocking code prevents execution from continuing until the operation is complete. Blocking calls hold off on returning until the I/O operation is finished. Synchronous results are returned from it.
What is the difference between blocking calls and non-blocking calls?Blocking calls hold off on returning until the I/O operation is finished. Synchronous results are returned from it. During the waiting period, nothing else in that process happens. In contrast, a non-blocking call uses a different method to check for completion and returns right away without any results.
Non-blocking code does not prevent execution from continuing while blocking code prevents execution from continuing until the operation is complete. Blocking occurs when subsequent JavaScript in the Node. js process needs to wait until a non-JavaScript activity is finished, according to the documentation for the language.
A program that is non-blocking does not prevent the execution of subsequent operations. Non-blocking techniques run in an asynchronous fashion. Asynchronously refers to the possibility that the program may not always run line by line.

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

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.An uniterruptible power supply

Given a binary search tree containing N integers, create an AVL tree containing the same values. You should not destroy the original BST in the process. What is the worst case time?
Answer:
answer : 0 (n log n )
Explanation:
Creating an AVL tree containing the same values and containing N integers and without destroying the original BST in the process, the worst case time will be : 0 ( n log n ) and this is because each insertion will take 0 (log n ) time
The worst case time for a binary search algorithm that contain N integers without destroying the original binary search tree (BST) is [tex]0(NlogN)[/tex]
What is a binary search?Binary search can be defined as an efficient algorithm that is designed and developed for searching an element from a sorted list of data, especially by using the run-time complexity of [tex]0(logN)[/tex].
Note: N is the total number of elements contained in a list.
In this scenario, the worst case time for this binary search algorithm that contain N integers without destroying the original binary search tree (BST) is given by [tex]0(NlogN)[/tex]
