you can use a minus sign to make a negative numberlike -2. What happens to each of the following 2++2
2 - -2
2+ - 2
2- +2
If we use a minus sign to make a negative number like -2. Then the following terms will be:
2 - -2 = 42 + -2 = 02 - +2 = 0What is calculation?A calculation is a methodical, well-thought-out process. Calculating the solution to a math problem is the first type of calculation, for which you might use a calculator. The calculation also includes applying logic to a non-numerical issue.
Plus, minus, multiply, and divide are the basic signs used in math to calculate problems. These signs also change when come n contact with each other, like plus and minus are equal to minus.
Like here, 2 - -2. Minus and minus is plus, so two plus two is four.
2 + -2 = 0, here plus minus = minus, so two minus two is 0.
Therefore, the calculation for the given is
2 - -2 = 42 + -2 = 02 - +2 = 0To learn more about calculation, refer to the link:

A. Data mapping
B. Data cleanup
C. Data loading
D. Data reporting
Answer:
I believe the answer would be D. Data Reporting!
hope this helps! <3
Answer:
Correct Answer D:- DATA Reporting.
Explanation:
Data reporting is the collection and submission of data that leads to accurate ground-based analysis incorrect data reporting can lead to extremely informed decision-making using wrong evidence. Data reporting is not only about information but also about data collection.
The reporting of data may be an unbelievably difficult task. In order to achieve the job of counting every resident of a country, census bureaus can hire even hundreds of thousands of workers.
Data reporting is a step that translates raw information into information. It is not the data analysis that transforms data and information into insights. If data is not reported, the problem is known as underreporting the opposite is wrong.
For which of the following values of A and B will the expression A || B be true?
A = False, B = False
Both A and B must be true
The expression is impossible to be true no matter the values of A and B.
A = False, B = True
Answer:
A = False, B = True
Explanation:
|| is equal OR. To the expression be true, you need one of them to be true or both.
A = TRUE, B = FALSE

Question 6 Which of the following statements about datasets used in Machine Learning is NOT true? 1 point Testing data is data the model has never seen before and is used to evaluate how good the model is Training subset is the data used to train the algorithm Validation data subset is used to validate results and fine-tune the algorithm's parameters Training data is used to fine-tune algorithm’s parameters and evaluate how good the model is
Answer:
Training data is used to fine-tune the algorithm’s parameters and evaluate how good the model is
Explanation:
The statement about datasets used in Machine Learning that is NOT true is "Training data is used to fine-tune algorithm’s parameters and evaluate how good the model is."
This is based on the fact that a Training dataset is a process in which a dataset model is trained for corresponding it essentially to fit the parameters.
Also, Testing the dataset is a process of examining the performance of the dataset. This refers to hidden data for which predictions are determined.
And Validation of dataset is a process in which results are verified to perfect the algorithm's details or parameters

Write a program named prices.c that repeatedly asks users to enter the price of an item until they enter zero. Prices less than zero will be ignored. The program will then print the number of items purchased, the subtotal of the prices, the sales tax charged (at a rate of 7.5%), and the grand total.
Answer:
Explanation:
The following is written in Java. It creates a while loop that requests price from the user and goes adjusting the quantity and subtotal as more prices are added. If 0 is entered it breaks the loop and outputs the quantity, subtotal, tax, and grand total to the user.
import java.util.Scanner;

You're installing two new hard drives into your network attached storage device. Your director asks that they be put into a RAID solution that offers redundancy over performance. Which would you use?
a. RAID 0
b. RAID 1
c. RAID 5
d. RAID 6
e. RAID 10
Answer:
d. RAID 6
Explanation:
RAID is a data storage technology that combines multiple physical disk drive components into a single logical unit. The functions of RAID is to provide performance and redundancy.
RAID 0 provides data stripping but it does not offer data stripping.
RAID 1 increases performance to about 2x but it limits the disk capacity to about 50%
RAID 5 provides redundancy and increased perfomance but it is limited to small disk drive.
RAID 6 also provides redundancy but it slows performance
RAID 10 increases performance and data protection.
RAID 6 is the best drive that offers redundancy over performance.
Write a function called reverse Return that is almost the same job as reverse, but instead of printing the letters straight to the screen, it returns a String in which the letters have been reversed. The function call would look like:
Answer:
The function in Python is as follows:
def reverse(inputstr):
outputstr = ""
for i in inputstr:
outputstr = i + outputstr
return outputstr
Explanation:
This defines the function
def reverse(inputstr):
This initializes the output string
outputstr = ""
This iterates through the input string
for i in inputstr:
This generates the output string by reversing the input string
outputstr = i + outputstr
This returns the reversed string
return outputstr

You issue a transmission from your workstation to the following socket on your LAN: 10.1.145:110. Assuming your network uses standard port designations, what Application layer protocol are you using
Answer:
POP
Explanation:
The application layer protocol that is been used here is POP, given that you issued a transmission to the socket on you LAN: 10.1.145:110. and you use a standard port designation
Reason:
110 ( port number ) represents a POP3 process that is always used in a TCP/IP network , and the socket address started with an IP address as well. hence we can say that the application layer protocol is POP

The question is incomplete. The complete question is :
Holly the Hacker has a list of 100,000 common passwords. She wants to use this list to break into UNIX-like systems that use a password file with lines consisting of:
The user's ID in plaintext.
10 bits of randomly chosen "salt," in plaintext.
The user's password, concatenated with the salt, and then encrypted.
There are very many such systems around the world, and Holly plans to steal the password files from as many as she can. The average system has 50 users in its password file.
Holly wants to create a master list of the encrypted versions of all the 100,000 passwords on her list, encrypted with all possible salt values. To create this master list, approximately how many encryptions of a password-concatenated-with-salt would Holly have to perform?
A. 2 million
B. 5 million
C. 100 million
D. 1 million
Solution :
It is given that the hacker, Holly wants break into the UNIX-like systems using 100,000 common passwords that she has on her list. The system has at an average of 50 users in the password files.
Therefore, to create a master list, Holly have to perform about 50 x 100,000 = 5,000,000 encryptions for the password concatenated-with-salt.
Thus the correct option is option (B). 5 million
