Answer:
a. This is an instance of overfitting.
Explanation:
In data modeling and machine learning practice, data modeling begins with model training whereby the training data is used to train and fit a prediction model. When a trained model performs well on training data and has low accuracy on the test data, then we say say the model is overfitting. This means that the model is memorizing rather Than learning and hence, model fits the data too well, hence, making the model unable to perform well on the test or validation set. A model which underfits will fail to perform well on both the training and validation set.

return myID;
}
}
Group of answer choices
a. String myName;
b. public String myName;
c. private myName;
d. private String myName;
Answer:private String myName;
Explanation:To declare a student's name, the following should be noted.
i. The name of the student is of type String
ii. Since all of the instance variables (myGPA and myID) have a private access modifier, then myName (which is the variable name used to declare the student's name) should be no exception. In other words, the student's name should also have a private access.
Therefore, XXX which declares a student's name should be written as
private String myName;
Option (a) would have been a correct option if it had the private keyword
Option (b) is not the correct option because it has a public access rather than a private access.
Option (c) is not a valid syntax since, although it has a private access, the data type of the variable myName is not specified.
Option (d) is the correct option.

{
print all values pointed by ptr. //complete this part
}
int main ( )
{
unsigned char data[ ] = { 9, 8, 7, 5, 3, 2, 1} ;
call the printValues function passing the array data //complete this part
}
Answer:
#include <stdio.h>
void printValues ( unsigned char *ptr, int count) // count is no of cells
{
for(int i=0; i<count; i++) {
printf("%d ", ptr[i]);
}
}
int main ( )
{
unsigned char data[ ] = { 9, 8, 7, 5, 3, 2, 1} ;
printValues( data, sizeof(data)/sizeof(data[0]) );
}
Explanation:
Remember that the sizeof() mechanism fails if a pointer to the data is passed to a function. That's why the count variable is needed in the first place.
It has been a hectic day for the cyber security team. The team is struggling to decide to which incident to devote the most resources. You are estimating the amount of time taken to recover from each incident Which scope factor are you considering?
Answer:
This definitely is a project management question. The scope factors to be considered are:
Varying Resource Levels Time FactorCompliance with Regulatory Factors Requirements of Stakeholders Quality of Management RisksLegal FactorsExplanation:
Any element or factor that can advantageously advance a project or negatively impact it is usually referred to as Project Scope Factor.
It is considered a desirable or nice-to-have ability to be able to spot these factors to the end that the positive ones are enhanced whilst negative ones are mitigated.
Failure, for instance, to timeously and properly identify factors that can negatively impact a project is most likely to result in a negative outcome.

For each compound below, identify any polar covalent bonds and indicate the direction of the dipole moment using the symbols δ +and δ-.
(a) HBr
(b) HCI
(c) H2O
(d) CH40
Answer:
H-Br bond is polar, hydrogen is partly positive and bromine is partly negative
H-Cl bond is polar, hydrogen is partly positive and bromine is partly negative
O-H bond in water is polar, hydrogen is partly positive and oxygen is partly negative
C-O bond in CH40 is polar, carbon is partly positive and oxygen is partly negative
Explanation:
A molecule possess a dipole moment when there is a large difference in electro negativity between two bonding atoms in the molecule.
The presence of dipole moments introduces polarity to the molecule. In all the molecules listed in the answer, the shared electron pair of the bond is closer to the more electronegative atom causing it to be partially negative while the less electronegative atom in the bond is partially positive.

It is not true that when you are listening to another person speak, you can avoid sending any messages by not speaking and not making eye contact. The correct option is 4.
What is communication?The process of communicating information, concepts, ideas, or sentiments between two or more people through a variety of means and channels, including verbal and nonverbal communication, is referred to as communication.
It is a myth that you may avoid transmitting any messages when you are listening to someone else speak by remaining silent and avoiding eye contact.
Your body language and nonverbal communication, such as your facial expressions and eye contact, can still convey information to the speaker even if you are not replying verbally or establishing eye contact.
Hence, even if a message is unintended or nonverbal, all types of communication entail sending and receiving messages.
Thus, the correct option is 4.

Answer:
-- While mainly a readability feature, we can technically use Enum to do things like spoof a Boolean type in C allowing us some level of functionality.
-- Enums are great for representing states and other common constants like colors.
-- Enums let us specifically value each constant we create.
Explanation:
Enums is a part of a programming language which helps a developer or a programmer to defined a set of the named constants. Using the enums will help in making it easier to document the intent and also to create set of distinct cases.
Option 1 is applicable as in the Boolean there are only TRUE and FALSE values. By using enum one can add more state like that of being difficult or normal or easy.
Option 4 is applicable because enums are used to represent various states and also other constants.
Option 5 is also applicable they allow the developer to create each value constant.

Write a C++ program to accept a 5 digit integer and to validate the input based on the following rules.
Rules
1) The input number is divisible by 2. 2) The sum of the first two digits is less than last two digits. if the input number satisfies all the rules, the system prints valid and invalid, otherwise,
Example 1:
Enter a value: 11222
Output: Input number is valid
Example 2:
Enter a value: 1234
Output: Input number is invalid
Answer:
#include <iostream>
#include <string>
#include <regex>
using namespace std;
int main()
{
cout << "Enter a 5-digit number: ";
string number;
cin >> number;
bool valid = regex_search(number, regex("^\\d{4}[02468]$"));
if (valid) {
valid = stoi(number.substr(0, 1)) + stoi(number.substr(1, 1))
< stoi(number.substr(3, 1)) + stoi(number.substr(4, 1));
}
cout << number << (valid ? " is valid" : " is invalid");
}
Explanation:
Regular expressions can do all of your checking except for the sum of digits check. The checks are i.m.o. easiest if you don't treat the input as a number, but as a string with digits in it.
The regex means:
^ start of string
\d{4} exactly 4 digits
[02468] one of 0, 2, 4, 6 or 8 (this is what makes it even)
$ end of string

Answer:
d. IPv4 Address 192.168.0.4 is associated with the globe IPv6 address 2001:db8:0:10:0:efe
Explanation:
The adapter setting will be associated with the global IP address. When Ipconfig command is operate the IP address finds the relevant domain and then address will use a different subnet. The network will use both IPv4 and IPv6 subnets in order to execute the command.
In the tunnel adapter settings, when performing the ipconfig command, the given output line depicts: D. IPv4 Address 192.168.0.4 is associated with the global IPv6 address 2001:db8:0:10:0:efe.

Explanation:
Given
The above method
Required
Which method call will give an incorrect response
(a) will return an incorrect response because 1900 is not a leap year.
When a year is divisible by 4, there are further checks to do before such year can be confirmed to be a leap year or not.
Since the method only checks for divisibility of 4, then it will return an incorrect response for years (e.g. 1900) that will pass the first check but will eventually fail further checks.

(1 pt) (2) Modify the program to use a loop to output a right triangle of height triangle_height. The first line will have one user-specified character, such as % or* Each subsequent line will have one additional user-specified character until the number in the triangle's base reaches triangle_height. Output a space after each user-specified character, including a line's last user-specified character.

Answer:
The modified program in Python is as follows:
triangle_char = input('Enter a character:\n')
triangle_height = int(input('Enter triangle height:\n'))
for i in range(triangle_height):
print(triangle_char * (i+1))
Explanation:
This gets the character from the user
triangle_char = input('Enter a character:\n')
This gets the height of the triangle from the user
triangle_height = int(input('Enter triangle height:\n'))
This iterates through the height
for i in range(triangle_height):
This prints extra characters up to the height of the triangle
print(triangle_char * (i+1))
Here's the modified program that incorporates the requested changes:
python
Copy code
triangle_char = input('Enter a character:\n')
triangle_height = int(input('Enter triangle height:\n'))
print('')
for i in range(1, triangle_height + 1):
line = triangle_char * i + ' ' * (triangle_height - i)
print(line)
This program uses a loop to iterate from 1 to triangle_height. In each iteration, it creates a line by concatenating triangle_char repeated i times with spaces (' ') repeated (triangle_height - i) times. The resulting line is then printed.
For example, if the user enters % as the character and 5 as the height, the output will be to make sure to maintain the indentation properly in your code for it to work correctly.

Answer:
" Non-persistent" is the right response.
Explanation:
A cross-site category of screenplay whereby harmful material would have to include a transaction to have been transmitted to that same web application or user's device is a Non-persistent attack.Developers can upload profiles with publicly available information via social media platforms or virtual communication or interaction.(CO 4 and 5) Create a program that will read in a list of test scores from the user and add them to a list. Ask the user in between each score if they want to continue (y/n). Display all of the scores entered and the total score at the end. Using the code below, put the code in the proper order Sample output: Welcome to the Test Score Program Add score: 88.45 Do you want to continue
Answer and Explanation:
Using Javascript:
function AddScores(){
Window.alert("Welcome to the Test Score Program");
var ScoreList= new Array();
ScoreList.push(Prompt("Add Score"));
var WhatNext= Confirm("do you want to continue?");
If(WhatNext===true) {
do{
ScoreList.push(Prompt("Add Score"));
}
While(
Confirm("do you want to continue?")===true;);
}
Alert(ScoreList);
Alert(ScoreList.reduce(function(a,b){return a +b};,0);)
}
AddScores();
From the above code in javascript programming language, we have created a list ScoreList and added elements to it using push method of the array object and a do...while loop that checks the condition and then adds the user's input to the array. We then alerted the array to the screen and then summed up the array elements and also alerted to the screen.

Following are the response to the given question:
Explanation:
The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.
Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.
As [tex]W_i < w_j[/tex], the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because [tex]v_i>v_j[/tex] and this strategy is better, our total profit has dropped. Contradiction.
