Answer:
Select SUM(HOURS), SUM(CHARGES) from employees
Explanation:
The table structure is not given. So, I will assume that the table name is "employees", the columns to retrieve are "hours" and "charges"
Having said that, the function to retrieve the total of column is the sum() function.
So, the query is as follows:
Select ----> This means that the query is to retrieve from the table
SUM(HOURS), SUM(CHARGES) --- This represent the records to retrieve
from employees ---- This represents the table to retrieve from.

what's the difference between pseudo code and natural language
Answer:
The pseudo-code describes steps in an algorithm or another system in plain language. Pseudo-Code is often designed for human reading rather than machine reading with structural conventions of a normal language of programming.
Natural languages consist of phrases, usually declarative phrases, with a sequence of information.
Explanation:
Pseudo-Code is often designed for human reading rather than machine reading with structural conventions of a normal language of programming. It usually omits information that is essential to the understanding of the algorithm by the machine, for example, variable declarations and language code.Easily human, but not machines, use the natural languages (like English).Natural languages also are creative. Poetry, metaphor, and other interpretations are permitted. Programming permits certain style differences, but the significance is not flexible.The aim of using pseudo-code is to make it easier for people to comprehensibly than standard programming language code and to describe the key principles of an algorithm efficiently and environmentally independently. It is usually used for documenting software and other algorithms in textbooks and scientific publications.x-1; while x ==1 disp(x) end, then the result a. infinity or b. (1)

Explanation:
For minimization problems, the optimal objective function value to the LP relaxation provides what for the optimal objective function value of the ILP problem?
Answer:
A lower bound on the optimal integer value.
Explanation:
The question is poorly typed. The original question requires the optimal solution of the objective function of a minimization problem
I will answer this question base on the above illustration.
When an objective function is to be minimized, it means that the objective function will take the feasible solution with the least value.
The least value are often referred to as the lower bound.

Ten examples of an interpreter
Answer:
Some popular examples of today's interpreters are:
Interpreter of PythonInterpreter for RubyPerl performerInterpreter for PHPMATLAB UCSD PascalExplanation:
An interpreter executes the commands directly in an object code or a machine code, written in a program or a scripting language.
The Interpreter can be referred to as system software that can read and execute the programme instead of interpreting programmes. This interpretation includes high-level source code, pre-compiled programmes and scripts.
It is important to note that the interpreter translates programme by programme line, meaning that one statement is translated on one go. This feature makes it easy for programmers to check any line on debugging but slows the whole programme running time.

Design a RomanNumerals class that takes a number within 1 to 10 and display the Roman numeral version of that number (I, II, III, IV, V … X). If the number entered by the user is outside the range of 1-10, the program should display an error message. Code a driver class RomanNumeralsApp to test the class by asking user to enter a number, creating an object of RomanNumerals and calling its methods getNumber, setNumber, convertNum, and displayResult to perform the described task.
Answer:
Explanation:
The following code is written in Java. It creates a RomanNumberals class with all of the requested methods, including a convertNum method and displayResults method. The user is then asked to input a number within the main method. A RomanNumeral object is created, passed the userInput and all of it's methods are called for testing. A test output can be seen in the attached image below.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter a number: ");
int number = in.nextInt();
RomanNumerals romanNumeral1 = new RomanNumerals();
romanNumeral1.setNumber(number);
System.out.println("Test getNumber Method: " + romanNumeral1.getNumber());
romanNumeral1.convertNumber();
romanNumeral1.displayResult();
}
}
class RomanNumerals {
int number;
String romanNumeral;
public RomanNumerals() {
}
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;

6.23 LAB: Convert to binary - functions Instructor note: This is a lab from a previous chapter that now requires the use of a function. If you weren't able to solve it before, think of this as a new opportunity. Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x // 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string. Ex: If the input is: 6 the output is: 110 Your program must define and call the following two functions. The function integer_to_reverse_binary() should return a string of 1's and 0's representing the integer in binary (in reverse). The function reverse_string() should return a string representing the input string in reverse. def integer_to_reverse_binary(integer_value) def reverse_string(input_string)
Answer:
The program in Python is as follows:
import math
def integer_to_reverse_binary(integer_value):
remainder = ""
while integer_value>=1:
remainder+=str(integer_value % 2)
integer_value=math.floor(integer_value/2)
reverse_string(remainder)
def reverse_string(input_string):
binaryOutput=""
for i in range(len(input_string)-1,-1,-1):
binaryOutput = binaryOutput + input_string[i]
print(binaryOutput)
integer_value = int(input("Enter a Number : "))
integer_to_reverse_binary(integer_value)
Explanation:
This imports the math module
import math
This defines the integer_to_reverse_binary function
def integer_to_reverse_binary(integer_value):
This initializes the remainder to an empty string
remainder = ""
This loop is repeated while the integer input is greater than or equal to 1
while integer_value>=1:
This calculates the remainder after the integer value is divided by 2
remainder+=str(integer_value % 2)
This gets the floor division of the integer input by 2
integer_value=math.floor(integer_value/2)
This passes the remainder to the reverse_string function
reverse_string(remainder)
The reverse_string function begins here
def reverse_string(input_string):
This initializes the binaryOutput to an empty string
binaryOutput=""
This iterates through the input string i.e. the string of the remainders
for i in range(len(input_string)-1,-1,-1):
This reverses the input string
binaryOutput = binaryOutput + input_string[i]
This prints the binary output
print(binaryOutput)
The main begins here
This gets input for integer_value
integer_value = int(input("Enter a Number : "))
This passes the integer value to the integer_to_reverse_binary function
integer_to_reverse_binary(integer_value)

(i) Deadlock
(ii) File manager
(iii) Process
(iv) Multiprogramming
(v) Software Classification
(vi) Virtual memory
Answer and Explanation:
Deadlock occurs when two operating systems on the same computer are hindering each other's execution, getting blocked, waiting for each one to run first. This can happen when a preemption has not occurred, when a mutual exclusion has occurred, or when one of the systems causes the other to not execute.
File manager is software that allows a computer user to create directories and organize files inside and outside of them.
Process is the term used to determine the functioning of computer software. When a software is started, it uses its own programming code to perform a specific activity.
Multiprogramming is the term used for the moment when an operating system allows the user to run more than one software at the same time. For this to happen, the computer needs to have a high processing capacity, to handle the effort of running several software simultaneously.
Software Classification is the process that determines the composition and different aspects that make up a software. In this way, it is possible to understand the usefulness and programming of this software.
Virtual memory is the use of secondary memory for caching. This allows the user to share files more securely and quickly, in addition to alleviating the problems that limited memory presents.

which feature of organisations to manage needs to know about to build and use information system successfully
The correct answer to this open question is the following.
The feature of organizations to manage needs to know about to build and use information system successful is the following.
Managers of successful organizations should know that companies have hierarchies and different structures in which these companies are organized.
Every company use systems and procedures that could be specialized to the degree the company requires. For that system to function, they have to be perfectly interconnected to all the areas of the company. The goal: to maximize efficiency and accomplish the goals.
Systems and procedures should take into consideration the culture and diversity of the workplace. There are interest groups in every organization that have special characteristics and requirements that have to be taken into consideration to create a much better system.
Good managers must be aware of these elements, and the different roles, goals, management styles, tasks, incentives, and departmental structure of the company so the system can better serve the purpose of the entire organization.

A python code only runs the except block when _____. Group of answer choices all the statements in the try block are executed an error occurs in the preceding try block the programmer manually calls the except block an error occurs anywhere in the code
Answer:
Python only running exception block when try block fails
Explanation:
i do cyber security and i was learning this in high school
In Python, try and except statements are used to catch and manage exceptions. Statements that can generate exceptions were placed within the try clause, while statements that handle the exception are put within the except clause.
An exception should be caught by except block, which is used to test code for errors that are specified in the "try" block. The content of the "except" block is executed if such a fault/error appears.In Python, the exception block only runs when an error occurs in the try block.Therefore, the answer is "try block fails ".
