Answer:
k = 3
Explanation:
K independent file servers
Average "uptime" of each server = 98%
To achieve 99.99% probability by the intranet
given that each server has an uptime = 98%
For the intranet to achieve 99.99% probability we have to choose more than 2 servers ( i.e. 3 servers ) incase any of the server goes down.
As each server posses an uptime of 98% it is almost impossible for all 3 servers to go down at the same time hence value of K = 3
It should be noted that the value of k to achieve 99.99 percent probability will be 3.
How to solve the probabilityFrom the information given, k is simply the independent file servers.
Also, the average uptime of each server is given as 98%. For the intranet to achieve 99.99% probability, it should be noted that more than 2 servers will be chosen.
In this case, it'll be impossible for the three servers to go down.

Explanation:
Over-activity on LinkedIn?
Answer:
Being over-enthusiastic and crossing the line always get you in trouble even if you’re using the best LinkedIn automation tool in the world.
When you try to hit the jackpot over the night and send thousands of connection requests in 24 hours, LinkedIn will know you’re using bots or tools and they will block you, temporarily or permanently.
This is clearly against the rules of LinkedIn. It cracks down against all spammers because spamming is a big ‘NO’ on LinkedIn.
What people do is that they send thousands of connection requests and that too with the same old spammy templates, “I see we have many common connections, I’d like to add you to my network.”
It will only create spam.
The LinkedIn algorithm is very advanced and it can easily detect that you’re using a bot or LinkedIn automation tool and you’ll be called out on it.

write a programmimg code in c++ for school based grading system, the program should accept the subject in the number of students from a user and store their details in the array of type student(class) the student class you have:
1. number student name, index number remarks as variables of type string, marks as integer and grade as char.
2. avoid function called getData which is used to get student details
3. avoid function called calculate which will work on the marks and give the corresponding great and remarks as given below on
Marks 70-100 grade A remarks excellent Mark 60-69 Grade B remarks very good marks 50-59 grade C remarks pass maths 0-49 grade F remarks fail
Answer:
The program is as follows:
#include <iostream>
#include <string>
using namespace std;
class Student{
string studName, indexNo, remarks; int marks; char grade;
public:
void getData(){
cin.ignore();
cout<<"ID: "; getline(cin,indexNo);
cout<<"Name:"; getline(cin,studName);
cout<<"Marks: ";cin>>marks; }
void calculate(){
if(marks>=70 && marks<=100){
remarks ="Excellent"; grade = 'A'; }
else if(marks>=60 && marks<=69){
remarks ="Very Good"; grade = 'B'; }
else if(marks>=50 && marks<=59){
remarks ="Pass"; grade = 'D'; }
else{
remarks ="Fail"; grade = 'F'; }
cout << "Grade : " << grade << endl;
cout << "Remark : " << remarks << endl; }
};
int main(){
int numStudents;
cout<<"Number of students: "; cin>>numStudents;
Student students[numStudents];
for( int i=0; i<numStudents; i++ ) {
cout << "Student " << i + 1 << endl;
students[i].getData();
students[i].calculate(); }
return 0;}
Explanation:
This defines the student class
class Student{
This declares all variables
string studName, indexNo, remarks; int marks; char grade;
This declares function getData()
public:
void getData(){
cin.ignore();
Prompt and get input for indexNo
cout<<"ID: "; getline(cin,indexNo);
Prompt and get input for studName
cout<<"Name:"; getline(cin,studName);
Prompt and get input for marks
cout<<"Marks: ";cin>>marks; }
This declares funcion calculate()
void calculate(){
The following if conditions determine the remark and grade, respectively
if(marks>=70 && marks<=100){
remarks ="Excellent"; grade = 'A'; }
else if(marks>=60 && marks<=69){
remarks ="Very Good"; grade = 'B'; }
else if(marks>=50 && marks<=59){
remarks ="Pass"; grade = 'D'; }
else{
remarks ="Fail"; grade = 'F'; }
This prints the grade
cout << "Grade : " << grade << endl;
This prints the remark
cout << "Remark : " << remarks << endl; }
};
The main begins here
int main(){
This declares number of students as integer
int numStudents;
Prompt and get input for number of students
cout<<"Number of students: "; cin>>numStudents;
This calls the student object to declare array students
Student students[numStudents];
This is repeated for all students
for( int i=0; i<numStudents; i++ ) {
Print number
cout << "Student " << i + 1 << endl;
Call function to get data
students[i].getData();
Call function to calculate
students[i].calculate(); }
return 0;}
A hierarchy chart can be helpful for a. planning the functions of a program b. naming the functions of a program c. showing how the functions of a program relate to each other d. all of the above e. a and c only
Answer:
Hence the correct options are option B and option C.
Explanation:
Hierarchy Chart means top to bottom structure 0f a function or a program or an organization.
Planning the functions of a program means deciding beforehand that what are the functions of a program and what to try to do and when to try to, hierarchy Charts are often helpful In doing/knowing this all.
Showing how the functions of a program relate to every other means what's the connection between two functions for instance if we have a hierarchical chart of a corporation member then we'll have the connection among the members of the team i.e., first, we'll have CEO, then Manager then team/ project lead then team members and by using hierarchical chart ready to " we will be able to identify the connection among them. during a similar way, we will have a relationship among the functions of a program using the hierarchical chart.

Copy the code above into your program but write all the other code for this assignment yourself. Do not copy any code from another source.
Write a function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters. Otherwise, it should return False.
Implement has_duplicates by creating a histogram using the histogram function above. Your implementation should use the counts in the histogram to decide if there are any duplicates.
Write a loop over the strings in the provided test_dups list. Print each string in the list and whether or not it has any duplicates based on the return value of has_duplicates for that string. For example, the output for "aaa" and "abc" would be the following.
aaa has duplicates

2.13 LAB: Branches: Leap Year
A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the
difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The
requirements for a given year to be a leap year are:
1) The year must be divisible by 4
2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400
Some example leap years are 1600, 1712 and 2016.
Write a program that takes in a year and determines whether that year is a leap year.
Ex If the input is
1712
the output is
1712 13 leap year.
Ex If the nouts
1913
the outoutis
1913 not leap year.
Written is Coral Language
Answer:
integer userInput
userInput = Get next input
if userInput % 400 == 0
Put userInput to output
Put " is a leap year" to output
else
if userInput % 4 == 0
Put userInput to output
Put " is a leap year" to output
else
Put userInput to output
Put " is not a leap year" to output
Explanation:
I don't know what is so special about Coral but here we go. I couldn't find and IDE that supported Coral so I just used their Coral simulator on their website. The first if statement on line 5 determines if the number is divisible by 400. If so, the leap year is on a century year e.g 1900 1800. If not, the else statement will be executed and the second if statement will execute. If the number is divisible by 4, it is a leap year. If not, the else statement gets executed in which case the number was not a century leap year or a leap year. After that the program terminates.
Hope this helped :) If it didn't let me know and I do my best to find out what went wrong.

Compute the acceleration of gravity for a given distance from the earth's center, distCenter, assigning the result to accelGravity. The expression for the acceleration of gravity is: (G * M) / (d2), where G is the gravitational constant 6.673 x 10-11, M is the mass of the earth 5.98 x 1024 (in kg) and d is the distance in meters from the earth's center (stored in variable distCenter).
#include
using namespace std;
int main() {
double G = 6.673e-11;
double M = 5.98e24;
double accelGravity;
double distCenter;
cin >> distCenter;
/* Your solution goes here */
cout << accelGravity << endl;
return 0;
}
Answer:
Replace /* Your solution goes here */ with the following expression
accelGravity = (G * M) / (distCenter *distCenter );
Explanation:
Required
Complete the code
The equivalent expression of (G * M) / (d^2) is:
(G * M) / (distCenter *distCenter );
The expression must be stored in accelGravity.
So, we have:
accelGravity = (G * M) / (distCenter *distCenter );

Write a program that prompts the user to input an integer that represents cents. The program will then calculate the smallest combination of coins that the user has. For example, 27 cents is 1 quarter, 0 nickel, and 2 pennies. That is 27=1*25+0*5+2*1.
Example program run 1:
Enter number of cents: 185
Pennies: 0
Nickels: 0
Dimes: 1
Quarters: 7
Example program run 2:
Enter number of cents: 67
Pennies: 2
Nickels: 1
Dimes: 1
Answer:
The program in Python is as follows:
cents = int(input("Cents: "))
qtr = int(cents/25)
cents = cents - qtr * 25
dms = int(cents/10)
cents = cents - dms * 10
nkl = int(cents/5)
pny = cents - nkl * 5
print("Pennies: ",pny)
print("Nickels: ",nkl)
print("Dimes: ",dms)
print("Quarters: ",qtr)
Explanation:
The program in Python is as follows:
cents = int(input("Cents: "))
This calculate the number of quarters
qtr = int(cents/25)
This gets the remaining cents
cents = cents - qtr * 25
This calculates the number of dimes
dms = int(cents/10)
This gets the remaining cents
cents = cents - dms * 10
This calculates the number of nickels
nkl = int(cents/5)
This calculates the number of pennies
pny = cents - nkl * 5
The next 4 lines print the required output
print("Pennies: ",pny)
print("Nickels: ",nkl)
print("Dimes: ",dms)
print("Quarters: ",qtr)

Write a program that uses linear recursion to generate a copy of an original collection in which the copy contains duplicates of every item in the original collection. Using linear recursion, implement a function that takes a list as user-supplied runtime input and returns a copy of it in which every list item has been duplicated. Given an empty list the function returns the base case of an empty list.
Answer: b
Explanation:
Program using linear recursion to duplicate items in a list:
def duplicate_list(lst):
if not lst:
return []
else:
return [lst[0], lst[0]] + duplicate_list(lst[1:])
# Example usage
user_input = input("Enter a list of items: ").split()
original_list = [item for item in user_input]
duplicated_list = duplicate_list(original_list)
print("Duplicated list:", duplicated_list)
How can a program use linear recursion to duplicate items in a list?By implementing a function that utilizes linear recursion, we can create a copy of an original list with duplicated items. The function duplicate_list takes a list lst as input and checks if it is empty. If the list is empty, it returns an empty list as the base case.
Otherwise, it combines the first item of the list with itself and recursively calls the function with the remaining items (lst[1:]). The duplicated items are added to the resulting list. This process continues until all items in the original list have been duplicated and the duplicated list is returned.

The advantage of returning a structure type from a function when compared to returning a fundamental type is that a. the function can return multiple values b. the function can return an object c. the function doesn’t need to include a return statement d. all of the above e. a and b only
Answer:
The advantage of returning a structure type from a function when compared to returning a fundamental type is that
e. a and b only.
Explanation:
One advantage of returning a structure type from a function vis-a-vis returning a fundamental type is that the function can return multiple values. The second advantage is that the function can return can an object. This implies that a function in a structure type can be passed from one function to another.
