Answer:
C = (3P+1) % 27
so when P will be max 26,when P is 26 the (3P+1) = 79. And 79/27 = 2 so let's give name n = 2.
Now doing reverse process
We get ,
P = ((27*n)+C-1)/3
Where n can be 0,1,2
So substituting value of n one by one and the C=7(corresponding index of h)
For n= 0,we get P=2, corresponding char is 'c'
For n=1,we get P=11, corresponding char is 'l'
For n=2,we get P= 20, corresponding cahr is 'u'.
So beside 'c',the system will generate 'h' for 'l' and 'u' also.
6 things you should consider when planning a PowerPoint Presentation.
Answer: I would suggest you consider your audience and how you can connect to them. Is your presentation, well, presentable? Is whatever you're presenting reliable and true? Also, no more than 6 lines on each slide. Use colors that contrast and compliment. Images, use images. That pulls whoever you are presenting to more into your presentation.

A university wants to schedule the classrooms for final exams. The attributes are given below:
course : course id, name, and department
section : section id, enrollment, and dependent as a weak entity set on course
room : room number, capacity, and building
exam: course id, section id, room number, and time.
1) Determine the relationships among these entity sets. Clearly specify the arity, the attributes, and the mapping cardinality of these relationships.
2) Construct an E-R diagram to for the scheduling system.
Answer:
See explaination
Explanation:
Clearly the entities are as follows:-
Course
Section
Room
Test
The relationship among entities are as follows:-
Course has Section
Test is conducted for Course
Test is conducted in Section
Test is conducted in Room
Attributes of each entities are as follows:-
Course (CourseID, Name, Department)
Section (SectionID, Enrollment)
Room (RoomNumber, Capacity, Building)
Test (Time)
Section is a week entity as, there may be same sections for different courses, therefore section uses the primary key of course entity as foreign key.
Also entity Test is dependent upon the entities Room,Section and Course, therefore primary keys of these entities will be used as foreign key in the Test entity.

Explanation:
Write the definition of a function words_typed, that receives two parameters. The first is a person's typing speed in words per minute (an integer greater than or equal to zero). The second is a time interval in seconds (an integer greater than zero). The function returns the number of words (an integer) that a person with that typing speed would type in that time interval.
//Method definition of words_typed
//The return type is int
//Takes two int parameters: typingSpeed and timeInterval
public static int words_typed(int typingSpeed, int timeInterval) {
//Get the number of words typed by
//finding the product of the typing speed and the time interval
//and then dividing the result by 60 (since the typing speed is in "words
// per minute" and the time interval is in "seconds")
int numberOfWords = typingSpeed * timeInterval / 60;
//return the number of words
return numberOfWords;
} //end of method declaration
Explanation:The code above has been written in Java and it contains comments explaining each of the lines of the code. Please go through the comments.
Answer:
I am writing the program in Python.
def words_typed(typing_speed,time_interval):
typing_speed>=0
time_interval>0
no_of_words=int(typing_speed*(time_interval/60))
return no_of_words
output=words_typed(20,30)
print(output)
Explanation:
I will explain the code line by line.
First the statement def words_typed(typing_speed,time_interval) is the definition of a function named words_typed which has two parameters typing_speed and time_interval.
typing_speed variable of integer type in words per minute.
time_interval variable of int type in seconds
The statements typing_speed>=0 and time_interval>0 means that value of typing_speed is greater than or equal to zero and value of time_interval is greater than zero as specified in the question.
The function words_typed is used to return the number of words that a person with typing speed would type in that time interval. In order to compute the words_typed, the following formula is used:
no_of_words=int(typing_speed*(time_interval/60))
The value of typing_speed is multiplied by value of time_interval in order to computer number of words and the result of the multiplication is stored in no_of_words. Here the time_interval is divided by 60 because the value of time_interval is in seconds while the value of typing_speed is in minutes. So to convert seconds into minutes the value of time_interval is divided by 60 because 1 minute = 60 seconds.
return no_of_words statement returns the number of words.
output=words_typed(20,30) statement calls the words_typed function and passed two values i.e 20 for typing_speed and 30 for time_interval.
print(output) statement displays the number of words a person with typing speed would type in that time interval, on the output screen.
Create a class called Hangman. In this class, Create the following private variables: char word[40], progress[40], int word_length. word will be used to store the current word progress will be a dash representation of the the current word. It will be the same length as the current word. If word is set to ‘apple’, then progress should be "‑‑‑‑‑" at the beginning of the game. As the user guesses letters, progress will be updated with the correct guesses. For example, if the user guesses ‘p’ then progress will look like "‑pp‑‑" Create a private function void clear_progress(int length). This function will set progress to contain all dashes of length length. If this function is called as clear_progress(10), this will set progress to "‑‑‑‑‑‑‑‑‑‑". Remember that progress is a character array; don’t forget your null terminator. Create the following protected data members: int matches, char last_guess, string chars_guessed, int wrong_guesses, int remaining. Create a public function void initialize(string start). This function will initialize chars_guessed to a blank string, wrong_guesses to 0. Set remaining to 6. Use strcpy() to set word to the starting word passed as start (You can use start.c_str() to convert it to a character array). Set word_length to the length of word. Call clear_progress in this function.

Design an application for Bob's E-Z Loans. The application accepts a client's loan amount and monthly payment amount. Output the customer's loan balance each month until the loan is paid off. b. Modify the Bob's E-Z Loans application so that after the payment is made each month, a finance charge of 1 percent is added to the balance.
Answer:
part (a).
The program in cpp is given below.
#include <stdio.h>
#include <iostream>
using namespace std;
int main()
{
//variables to hold balance and monthly payment amounts
double balance;
double payment;
//user enters balance and monthly payment amounts
std::cout << "Welcome to Bob's E-Z Loans application!" << std::endl;
std::cout << "Enter the balance amount: ";
cin>>balance;
std::cout << "Enter the monthly payment: ";
cin>>payment;
std::cout << "Loan balance: " <<" "<< "Monthly payment: "<< std::endl;
//balance amount and monthly payment computed
while(balance>0)
{
if(balance<payment)
{ payment = balance;}
else
{
std::cout << balance <<"\t\t\t"<< payment << std::endl;
balance = balance - payment;
}
}
return 0;
}
part (b).
The modified program from part (a), is given below.
#include <stdio.h>
#include <iostream>
using namespace std;
int main()
{
//variables to hold balance and monthly payment amounts
double balance;
double payment;
double charge=0.01;
//user enters balance and monthly payment amounts
std::cout << "Welcome to Bob's E-Z Loans application!" << std::endl;
std::cout << "Enter the balance amount: ";
cin>>balance;
std::cout << "Enter the monthly payment: ";
cin>>payment;
balance = balance +( balance*charge );
std::cout << "Loan balance with 1% finance charge: " <<" "<< "Monthly payment: "<< std::endl;
//balance amount and monthly payment computed
while(balance>payment)
{
std::cout << balance <<"\t\t\t\t\t"<< payment << std::endl;
balance = balance +( balance*charge );
balance = balance - payment;
}
if(balance<payment)
{ payment = balance;}
std::cout << balance <<"\t\t\t\t\t"<< payment << std::endl;
return 0;
}
Explanation:
1. The variables to hold the loan balance and the monthly payment are declared as double.
2. The program asks the user to enter the loan balance and monthly payment respectively which are stored in the declared variables.
3. Inside a while loop, the loan balance and monthly payment for each month is computed with and without finance charges in part (a) and part (b) respectively.
4. The computed values are displayed for each month till the loan balance becomes zero.
5. The output for both part (a) and part (b) are attached as images.

string name; // variables
int number;
cin >> name >> number; // taking user input
while(number != 0)
{
// printing output

Dave owns a construction business and is in the process of buying a laptop. He is looking for a laptop with a hard drive that will likely continue to function if the computer is dropped. Which type of hard drive does he need?
Answer:
Solid state drive
Explanation:
The term solid-state drive is used for the electronic circuitry made entirely from semiconductors. This highlights the fact that the main storage form, in terms of a solid-state drive, is via semiconductors instead of a magnetic media for example a hard disk. In lieu of a more conventional hard drive, SSD is built to live inside the device. SSDs are usually more resistant to physical shock in comparison to the electro-mechanical drives and it functions quietly and has faster response time. Therefore, SSD will be best suitable for the Dave.
*Sometimes it is difficult to convince top management to commit funds to develop and implement a SIS why*
Step-by-step Explanation:
SIS stands for: The Student Information System (SIS).
This system (a secure, web-based accessible by students, parents and staff) supports all aspects of a student’s educational experience, and other information. Examples are academic programs, test grades, health information, scheduling, etc.
It is difficult to convince top management to commit funds to develop and implement SIS, this can be due to a thousand reasons.
The obvious is that the management don't see the need for it. They would rather have students go through the educational process the same way they did. Perhaps, they just don't trust the whole process, they feel more in-charge while using a manual process.

The equation of certain traveling waves is y(x.t) = 0.0450 sin(25.12x - 37.68t-0.523) where x and y are in
meters, and t in seconds. Determine the following:
(a) Amplitude. (b) wave number (C) wavelength. (d) angular frequency. (e) frequency: (1) phase angle, (g) the
wave propagation speed, (b) the expression for the medium's particles velocity as the waves pass by them, and (i)
the velocity of a particle that is at x=3.50m from the origin at t=21.os
Answer:
A. 0.0450
B. 4
C. 0.25
D. 37.68
E. 6Hz
F. -0.523
G. 1.5m/s
H. vy = ∂y/∂t = 0.045(-37.68) cos (25.12x - 37.68t - 0.523)
I. -1.67m/s.
Explanation:
Given the equation:
y(x,t) = 0.0450 sin(25.12x - 37.68t-0.523)
Standard wave equation:
y(x, t)=Asin(kx−ωt+ϕ)
a.) Amplitude = 0.0450
b.) Wave number = 1/ λ
λ=2π/k
From the equation k = 25.12
Wavelength(λ ) = 2π/25.12 = 0.25
Wave number (1/0.25) = 4
c.) Wavelength(λ ) = 2π/25.12 = 0.25
d.) Angular frequency(ω)
ωt = 37.68t
ω = 37.68
E.) Frequency (f)
ω = 2πf
f = ω/2π
f = 37.68/6.28
f = 6Hz
f.) Phase angle(ϕ) = -0.523
g.) Wave propagation speed :
ω/k=37.68/25.12=1.5m/s
h.) vy = ∂y/∂t = 0.045(-37.68) cos (25.12x - 37.68t - 0.523)
(i) vy(3.5m, 21s) = 0.045(-37.68) cos (25.12*3.5-37.68*21-0.523) = -1.67m/s.

The Monte Carlo (MC) Method (Monte Carlo Simulation) was first published in 1949 by Nicholas Metropolis and Stanislaw Ulam in the work "The Monte Carlo Method" in the Journal of American Statistics Association. The name Monte Carlo has its origins in the fact that Ulam had an uncle who regularly gambled at the Monte Carlo casino in Monaco. In fact, way before 1949 the method had already been extensively used as a secret project of the U.S. Defense Department during the so-called "Manhattan Project". The basic principle of the Monte Carlo Method is to implement on a computer the Strong Law of Large Numbers (SLLN) (see also Lecture 9). The Monte Carlo Method is also typically used as a probabilistic method to numerically compute an approximation of a quantity that is very hard or even impossible to compute exactly like, e.g., integrals (in particular, integrals in very high dimensions!). The goal of Problem 2 is to write a Python code to estimate the irrational number

Zoom Vacuum, a family-owned manufacturer of high-end vacuums, has grown exponentially over the last few years. However, the company is having difficulty preparing for future growth. The only information system used at Zoom is an antiquated accounting system. The company has one manufacturing plant located in Iowa; and three warehouses, in Iowa, New Jersey, and Nevada. The Zoom sales force is national, and Zoom purchases about 25 percent of its vacuum parts and materials from a single overseas supplier. You have been hired to recommend the information systems Zoom should implement in order to maintain their competitive edge. However, there is not enough money for a full-blown, cross-functional enterprise application, and you will need to limit the first step to a single functional area or constituency. What will you choose, and why?
Answer:
The best advice for Zoom Vacuum is to start with a Transaction Processing System(TPS). This system will process all the day to day transactions of the system. It is like a real time system where users engage with the TPS and generate, retrieve and update the data. it would be very helpful in lowering the cost of production and at the same time manufacture and produce standard quality products.
Although, TPS alone would not be sufficient enough. so Management Information System(MIS) would be needed, that can get the data from the TPS and process it to get vital information.
This MIS will bring about information regarding the sales and inventory data about the current and well as previous years.
With the combination of TPS as well as MIS is a minimum requirement for a Zoom Vacuum to become successful in the market.
Explanation:
Solution
When we look at the description of the Zoom Vacuum manufacturing company closely, we see that the business is currently a small scale business which is trying to become a small to mid scale business. This claim is supported by the fact that there is only one manufacturing plant and three warehouses. And here, we also need to have the knowledge of the fact that small business major aim is to keep the cost low and satisfy the customers by making good products. So we need to suggest what information system is best suited for small scale business enterprises.
The best recommendation would be to start with a Transaction Processing System(TPS). This system will process all the day to day transactions of the system. It is like a real time system where users interact with the TPS and generate, retrieve and modify the data. This TPS would be very helpful in lowering the cost of production and at the same time manufacture and produce standard quality products . Also TPS can help in communicating with other vendors.
But TPS along would not be sufficient. Also Management Information System(MIS) would be required that can get the data from the TPS and process it to get vital information. This MIS will help in generating information regarding the sales and inventory data about the current and well as previous years. Also MIS can create many types of graphical reports which help in tactical planning of the enterprise.
So a combination of TPS as well as MIS is a minimum requirement for a Zoom Vacuum to become successful in the market.
g Q 2 Suppose I need a data structure having the following characteristics: a) must be very space efficient, and b) I have a good idea of how much total data needs to be stored. b) must have fastest access possible, and c) once I add an item to the data structure, I do not remove it. Part 1: What data structure would I choose and why? (2,4) Part 2: If I remove characteristic b, what similar data structure is a possible candidate?
Explanation:
a.I would choose an advanced data structure like dispersion tables.
Scatter tables, better known as hash tables, are one of the most frequently used data structures. To get an initial idea, scatter tables make it possible to have a structure that relates a key to a value, such as a dictionary. Internally, the scatter tables are an array. Each of the array positions can contain none, one or more dictionary entries.
It will normally contain a maximum of one, which allows quick access to the elements, avoiding a search in most cases. To know at which position in the array to search or insert a key, a scatter function is used. A scatter function relates each key to an integer value. Two equal keys must have the same dispersion value, also called a hash value, but two different keys can have the same dispersion value, which would cause a collision.
B. If I eliminated the characteristic b, a possible candidate keeping the previous characteristics would be: Balanced binary trees
Balanced binary trees are data structures that store key-data pairs, in an orderly way according to the keys, and allow quick access to the data, given a particular key, and to go through all the elements in order.
They are appropriate for large amounts of information and have less overhead than a scatter table, although the access time is of greater computational complexity.
Although the storage form has a tree structure internally, this is not externalized in the API, making the handling of the data transparent. They are called balanced because, each time they are modified, the branches are rebalanced in such a way that the height of the tree is as low as possible, thus shortening the average time of access to the data.

Explanation:
In Java please:
Palindrome reads the same from left or right, mom for example. There is a palindrome which must be modified, if possible. Change exactly one character of the string to another character in the range ascii[a-z] so that the string meets the following three conditions:
a. The new string is lower alphabetically than the initial string.
b. The new string is the lowest value string alphabetically that can be created from the original palindrome after making only one change.
c. The new string is not a palindrome.
Return the new string, or, if it not possible to create a string meeting the criteria, return the string IMPOSSIBLE.
Example:
palindromeStr = 'aaabbaaa'
O Possible strings lower alphabetically than 'aaabbaaa' after one change are [aaaabaaa', 'aaabaaaa').
O aaaabaaa' is not a palindrome and is the lowest string that can be created from palindromeStr.
Answer:
See explaination
Explanation:
public class PalindromeChange {
public static void main(String[] args) {
System.out.println("mom to non palindrom word is: "+changTONonPalindrom("mom"));
System.out.println("mom to non palindrom word is: "+changTONonPalindrom("aaabbaaa"));
}
private static String changTONonPalindrom(String str)
{
int mid=str.length()/2;
boolean found=false;
char character=' ';
int i;
for(i=mid-1;i>=0;i--)
{
character = str.charAt(i);
if(character!='a')
{
found=true;
break;
}
}
if(!found)
{
for(i=mid+1;i<str.length();i++)
{
character = str.charAt(i);
if(character!='a')
{
found=true;
break;
}
}
}
// This gives the character 'a'
int ascii = (int) character;
ascii-=1;
str = str.substring(0, i) + (char)ascii+ str.substring(i + 1);
return str;
}
}

Explanation:
Any set of logic-gate types that can realize any logic function is called a complete set of logic gates. For example, 2-input AND gates, 2- input OR gates, and inverters are a complete set, because any logic function can be expressed as a sum of products of variables and their complements, and AND and OR gates with any number of inputs can be made from 2-input gates. Do 2-input NAND gates form a complete set of logic gates? Prove your answer.
Answer:
Explanation:
We can use the following method to solve the given problem.
The two input NAND gate logic expression is Y=(A*B)'
we can be able to make us of this function by using complete set AND, OR and NOT
we take one AND gate and one NOT gate
we are going to put the inputs to the AND gate it will give us the output = A*B
we collect the output from the AND and we put this as the input to the NOT gate
then we will get the output as = (A*B)' which is needed

Fill in the empty function so that it returns the sum of all the divisors of a number, without including it. A divisor is a number that divides into another without a remainder. in python
Program explanation:
In the given program code, a method "sum_divisors" is declared that takes "n" variable in its parameter.Inside the method, the "s" variable is declared, which holds a value which is "0", and used a for loop that defines counts the range values.In the loop, a conditional statement is declared that check remainder value equal to 0 and adds value in "s" variable and return its value.Program code:
def sum_divisors(n):#defining a method sum_divisors that takes a parameter
s = 0#defining a variable s that hold a value 0
for x in range(1,n):#defining a for loop that use n variable to check range value
if(n%x==0):#use if to check remainder value equal to 0
s += x#adding value in s variable
return s#return s value
print(sum_divisors(6))#calling method
print(sum_divisors(12))#calling method
