Answer:
0.95
Explanation:
Reliability is a assurance that a machine would have an efficiency of one or close to one.
The minimum allowable reliability R;
(1 - R) x 2000 = 100
Make R the subject of the formula;
R = 1 - (100/ 2000)
R = 1 - 0.05
= 0.95

Answer:
The machine code is located at x210F.
Explanation:
The DATA is located at x3100 while the DATA label is located at the x310F (in hex) in the memory which is F address away (8 bits) from the DATA itself. The machine code location is relative to the address of the DATA label.
To prevent long page load times for pages containing images, it is best to use a compressed file format such as JPG, as well as appropriate image dimensions and
resolution.
magnification.
orientation.
colors.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The given options to this question are:
resolution. magnification. orientation. colors.The correct option to this question is 1. i.e.
Resolution.
The resolution of an image determines how many pixels per inch an image contains. Image having a higher resolution takes long page load times for a page and lower resolution takes less page load time. So, to prevent long page load times for pages containing images, it is best to use compressed file formation as well as appropriate image dimension and resolution.
While other options are not correct because:
Magnification, orientation, and color does not affect the page load time. Page load time for images only affected by the dimension and resolution of the images.
Write two statements that each use malloc to allocate an int location for each pointer. Sample output for given program:
numPtr1 = 44, numPtr2 = 99
#include
#include
int main(void) {
int* numPtr1 = NULL;
int* numPtr2 = NULL;
/* Your solution goes here */
*numPtr1 = 44;
*numPtr2 = 99;
printf("numPtr1 = %d, numPtr2 = %d\n", *numPtr1, *numPtr2);
free(numPtr1);
free(numPtr2);
return 0;
}
Answer:
#include <stdio.h>
#include <stdlib.h>
int main(void) {
int* numPtr1 = NULL;
int* numPtr2 = NULL;
/* Your solution goes here */
numPtr1 = (int *) malloc(10);
numPtr2 = (int *) malloc(20);
*numPtr1 = 44;
*numPtr2 = 99;
printf("numPtr1 = %d, numPtr2 = %d\n", *numPtr1, *numPtr2);
free(numPtr1);
free(numPtr2);
return 0;
}
Explanation:
The C library malloc function is used to assign memory locations (in bytes) to variables. It accepts the size parameter and returns a pointer to the specified variable location.
The two malloc statements above assign two memory locations 10 and 20 to the numPtr1 and numPtr2 integer variables respectively.

Sales Company:
W.D. Widgets is a small company that sells widgets. They're mostly made up of salespeople who work with lots of clients.
You've taken over as the sole IT person for this company of 80-100 people.
R teils you to provision a machine for a new employee, you order the hardware directly from a business vendor.
You keep one or two machines in stock, in case of emergency. The users receive a username that you generate for them.
You then give them an orientation on how to login when they start. You currently manage all of your machines using
Windows Active Directory. The company uses only Windows computers. When a new computer is provisioned, you have
to nistallots of sales-specific applications manually onto every machine. This takes a few hours of your time for each
15
machine. When someone has an IT-related request, they email you directly to help them.
Almost all software is kept in-house, meaning that you're responsible for the email server, local machine software, and
instant messenger. None of the company's services are kept on the cloud.
Customer data is stored on a single file server. When a new salesperson starts, you also map this file server onto their
local machine, so that they can access it like a directory. Whoever creates a folder on this server owns that folder and
everything in it. There are no backups to this critical customer data. If a user deletes something, it may be lost for
everyone.

O popleft
addleft
Answer: appendleft
Explanation: Edge 2021
The method that adds an element for the information at the beginning of a deque is append left. Thus option (A) is correct.
What is an information?An information refers to something that has the power to inform. At the most fundamental level information pertains to the interpretation of that which may be sensed.
The digital signals and other data use discrete signs or alogrithms to convey information, other phenomena and artifacts such as analog signals, poems, pictures, music or other sounds, and the electrical currents convey information in a more continuous form.
Information is not knowledge itself, but its interpretation is important. An Information can be in a raw form or in an structured form as data. The information available through a collection of data may be derived by analysis by expert analysts in their domain.

Explanation:
Professor Gig A. Byte needs to store text made up of the characters A with frequency 6, B with frequency 2, C with frequency 3, D with frequency 2, and E with frequency 8. Professor Byte suggests using the variable length codes:
Character Code
A 1
B 00
C 01
D 10
E 0
The professor argues that these codes store the text in less space than that used by an optimal Huffman code. Is the professor correct?
Answer:
This is not true
Explanation:
The optimal Huffman code is used to encrypt and compress text files. It uses fixed-length code or variable-length code for encryption and compression of data.
The professor's character code is similar to Huffman's variable-length coding which uses variable length od binary digits to represent the word strings. The file size of the text file above is;
= 6 x 1 + 2 x 2 + 3 x 2 + 2 x 2 + 8 x 1 = 28 bits
This would be the same for both cases.
The encrypt would be the problem as the encoded and decoding of the characters B and E may cause an error.
Define a toString prototype method that returns the cat's name, gender, and age separated by semicolons.
Answer:
Following are the program to this question:
import java.util.*;//import package for user input
public class Main//defining main class
{
public static String Cat (String name, String gender, int age)//defining string method Cat that accept parameter value
{
return name + ';' + gender + ';' + age;//return parameter value
}
public static void main(String[] args) //defining main method
{
String name,gender;//defining String variable
int age;//defining integer variable
System.out.println("Enter name, gender and age: ");//print message
Scanner obx=new Scanner(System.in);//creating Scanner class object for user input
name=obx.next();//input name value
gender=obx.next();//input gender value
age=obx.nextInt();// input age value
System.out.println(Cat(name,gender,age));//print return method value
}
}
Output:
Enter name, gender and age:
dani
Female
12
dani;Female;12
Explanation:
In the above-given code, a string method Cat is declared, that accepts three variable "name, gender, and age", inside the method return keyword is used that returns the parameter values.
In the main method, the above parameter variable is declared, which is used to input value from the user-end, and used the print method to print its return value.

#include <iostream>
using namespace std;
int main() {
int num, check=0;
for(int num = 1; num<=100;num++){
for(int i = 2; i <= num/2; i++) {
if(num % i == 0) {
check=1;
break; } }
if (check==0) { cout <<num<<" "; }
check = 0;
}
return 0;
}
Explanation:
This line declares num as integer which represents digits 1 to 100.
A check variable is declared as integer and initialized to 0
int num, m=0, check=0;
This for loop iterates from 1 to 100
for(int num = 1; num<=100;num++){
This iterates from 2 to half of current digit
for(int i = 2; i <= num/2; i++) {
This checks for possible divisors
if(num % i == 0) {
If found, the check variable is updated to 1
check=1;
And the loop is terminated
break; } }
The following if statement prints the prime numbers
if (check==0) { cout <<num<<" "; }
check = 0;

using namespace std;
void Search_heavy_orange(int arr[], int l, int r, int x)
{
int count = 0, m = 0;
while (l <= r) {
m = l + (r - l) / 2;
// Check if x is present at mid
if (arr[m] == x) {
count++;
}
// If x greater, ignore left half
if (arr[m] < x) {
l = m + 1;
count++;
}
// If x is smaller, ignore right half
else {
r = m - 1;
count++;
}
}
cout << "............For Worst Case......." << endl;
cout << "Orange with heavy weight is present at index " << m << endl;

// orange is 150 gm
int orange_weight[128];
for (int i = 0; i < 127; i++) {
orange_weight[i] = 100;
}
// At worst case the heavy orange should be at last position
// inside the basket : 127
orange_weight[127] = 150;

Explanation:
Write a program that calculates the average of N integers. The program should prompt the
user to enter the value for N and then afterward must enter all N numbers. If the user enters a
negative value for N, then an exception should be thrown (and caught) with the message “ N
must be positive.” If there is any exception as the user is entering the N numbers, an error
message should be displayed, and the user prompted to enter the number again.
Answer:
def Average(num):
if num == 0:
return 0
val = 0
trueNum = num
for i in range(0, num):
try:
val += int(input("Enter value (%d out of %d): " % (i+1,num)))
except Exception as e:
print ("Error processing value. Non integer detected.")
try:
val += int(input("Enter value (%d out of %d): " % (i+1,num)))
except Exception as e:
print ("Error processing value. Non integer detected.")
print ("OMITTING value from average.")
trueNum -= 1
return val/trueNum
def main():
try:
num = int(input("Enter a value N for amount of items: "))
if num < 0:
raise(ValueError)
except ValueError:
print ("N must be positive integer.")
exit(1)
print("Average: ", Average(num))
exit(0)
if __name__ == "__main__":
main()
Explanation:
This program is written in Python to collect some integer value from the user as an upper bound of integers to be input for an average. Using this upper bound, the program checks to validate it is indeed an integer. If it not an integer, then the program alerts the user and terminates. If it is a user, the Average function is called to begin calculation. Inside the Average function, the user is prompted for an integer value repeatedly up until the upper bound. Using the sum of these values, the program calculates the average. If the user inputs a non integer value, the program will alert the user that the value must be an integer and ask again. If the user again inputs a non integer value, that iteration will be omitted from the final average. The program this prints the calculated average to the user.

}
else {
System.out.print(currLetter + " ");

}
public static void main (String [] args) {
char startingLetter;
startingLetter = 'z';
/* Your solution goes here */
}
}
Answer:
RecursiveCalls.backwardsAlphabet(startingLetter);
Explanation:
The statement that is needed is a single-line statement. Since the class RecursiveCalls is already in the same file we can simply use that class and call its function without making a new class object. Once we call that class' function we simply pass the variable startingLetter (which is already provided) as the sole parameter for the function in order for it to run and use the letter 'z' as the starting point.
RecursiveCalls.backwardsAlphabet(startingLetter);
