What are the consequences of writing selection structures to include an unnecessary nested selection structure ?​

Answer:

-16000

Explanation:

Given

P(success) = 0.75

Amount generated on success, X = 240000

P(not successful) = P(success)' = 1 - 0.75 = 0.25

Revenue generated, 0

Product development cost = 196000

Profit = Revenue - cost

When successful ; 240000 - 196000 = 44000

Unsuccessful ; 0 - 196000 = - 196000

x __________ 44000 _____ - 196000

P(x) _________ 0.75 _________ 0.25

The expected value ; E(X) = Σx * p(x)

Σx * p(x) = (44000 * 0.75) + (-196000 * 0.25)

= 33000 + - 49000

= - 16000

Hence, the company should not make the product

Central processing unit (CPU)

Explanation:

A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user.

The central processing unit (CPU) is typically considered to be the brain of a computer system. It is the system unit where all of the processing and logical control of a computer system takes place.

Hence, the most important component in a computer is the central processing unit (CPU) because without it, it is practically impossible for the computer to run any software application or program.

Additionally, the component of the central processing unit (CPU) that controls the overall operation of a computer is the control unit. It comprises of circuitry that makes use of electrical signals to direct the operations of all parts of the computer system. Also, it instructs the input and output device (I/O devices) and the arithmetic logic unit on how to respond to informations sent to the processor.

Answer:

ALTER TABLE Products

ADD Products_price float(5,2) DEFAULT 9.99,

ADD Adding_time datetime;

Explanation:

So at first we need to use ALTER TABLE statement, when we use this statement we also need to provide the table name. In this case, i assume it is 'Products'.

Then, as per question, we need to add two columns.

The first one is 'product_price' and it contains decimal points. So, we need to use ADD statement and give a column name like 'Prodcuts_price' and its datatype 'float' because it contains decimal or floating points. so, for 3 digits on the left and 2 digits on the right, it makes a total of 5 digits. So, we need to declare it like this. (5,2) it means a total of 5 digits and 2 after the decimal point. after that, we need to set our Default value using the DEFALUT statement. so DEFAULT 9.99. it will set the default value to 9.99 for existing products.

And for our next column, we give its a name like 'Adding_time' then it's datatype 'datetime' because it will contain date and times.

Answer:

[tex]E = 14.81\%[/tex]

Explanation:

Given

[tex]n = 150[/tex]

[tex]\sigma = 0.78[/tex]

[tex]c = 0.98[/tex]

Required

The margin of error (E)

This is calculated as:

[tex]E = z * \frac{\sigma}{\sqrt{n}}[/tex]

When confidence level = 0.98 i.e. 98%

The z score is: 2.326

So, we have:

[tex]E = 2.326 * \frac{0.78}{\sqrt{150}}[/tex]

[tex]E = 2.326 * \frac{0.78}{12.247}[/tex]

[tex]E = \frac{2.326 *0.78}{12.247}[/tex]

[tex]E = \frac{1.81428}{12.247}[/tex]

[tex]E = 0.1481[/tex]

Express as percentage

[tex]E = 14.81\%[/tex]

Which of the options is not possible?

From the question, we understand that:

[tex]attempts \to [1,4][/tex] --- attempt can only assume values 1, 2, 3 and 4

The following "if statement" is repeated three times

IF RANDOM[1,10] <= 7:

   success = success + 1

This implies that the maximum value of the success variable is 3

The first printed value is the attempt variable

The second printed value is the success variable.

From the list of given options, (a), (b) and (d) are within the correct range of the two variable.

While (c) is out of range because the value printed for variable success is 7 (and 7 is greater than the expected maximum of 3)

Answer:

1) The value of x will be 6.

2) The value of y will be 7.

Explanation:

1) The value of x will be 6.  

The enum values are labeled by default from 1. This means that Sun = 1, Mon = 2, Tue = 3 and so on.  

So, x = Mon = 2 and y = Sat = 6  

x increases up to y = 6 in the while loop.  

and then y also increments by 1.  

2)So the value of y = 7.  

You will need actual printf("Sun") or printf("Mon") for printing the actual text for the enum.

Systems implementation & evaluation

What is systems implementation?

What are the tools for physical systems design?

What are the issues to consider before an information system is operational?

What are the key indicators of a quality system?

What are the techniques for systems evaluation?

Systems implementation is the process of:

defining how the information system should be built (i.e., physical system design),

ensuring that the information system is operational and used,

ensuring that the information system meets quality standard (i.e., quality assurance).

Systems design

Conceptual design – what the system should do

Logical design – what the system should look to the user

Physical design – how the system should be built

Physical system design using structured design approach:

à To produce a system that is easy to read, code, and maintain

1. Factoring: decomposition

2. Span of control: 9 subordinate modules

3. Reasonable size: 50-100 LOC

4. Coupling: minimize inter-module dependency

5. Cohesion: single module functionality

6. Shared use: multiple calls to lower level modules from different bosses

Structured design tools

· Organization of programs and program modules (structure chart)

· Processing logic specification in each module (pseudocode)

Structure chart – to show graphically

how the various program parts/modules of an information system are physically organized hierarchically

how the modules communicate with each other through data couple (data exchange) and flag (control/message)

how the modules are related to each other in terms of sequence, selection, and repetition

Answer:

The program in C++ is as follows:

#include <iostream>

#include <vector>

using namespace std;

int main(){

vector<int> nums;

int num;

cin>>num;

while(num != -1){

 nums.push_back(num);

 cin>>num; }  

for (auto i = nums.begin(); i != nums.end(); ++i){

    cout << *i <<endl; }

return 0;

}

Explanation:

This declares the vector

vector<int> nums;

This declares an integer variable for each input

int num;

This gets the first input

cin>>num;

This loop is repeated until user enters -1

while(num != -1){

Saves user input into the vector

 nums.push_back(num);

Get another input from the user

 cin>>num; }

The following iteration print the vector elements

for (auto i = nums.begin(); i != nums.end(); ++i){

    cout << *i <<endl; }

Explanation:

Answer:

Following are the program to the given question:

public class Main//defining Main method

{

   char maxChar (char x1,char x2)//defining a method maxChar that takes two char parameter

   {

       if(x1<x2)//use if to compare char value

       {

           return x1;//return first char value

       }

       else//else block

       {

           return x2;//return second char value

       }

   }

public static void main(String[] args)//defining main method

{

    char x1,x2;//defining char variable

    x1='d';//use char to hold value

    x2='a';//use char to hold value

    Main ob=new Main();//creating class Object

 System.out.println(ob.maxChar(x1,x2));//calling method and prints its return value

}

}

Output:

a

Explanation:

In this code, a method "maxChar" is defined that holds two char variable "x1,x2" in its parameters, and use if conditional statement that checks the parameter value and print its return value.

In the main method, two char variable is declared that hold char value and passing the value in the method and prints its return value.

   System.out.print("Enter nr to purchase: ");

   int nrPurchased = input.nextInt();

   System.out.print("Enter nr to re-stock: ");

   int nrRestock = input.nextInt();

   machine.Transaction(nrPurchased, nrRestock);

   input.close();

 }

}

class VendingMachine {

 private int inventory;

 public VendingMachine(int initialInventory) {

   inventory = initialInventory;

 }

 public void Transaction(int nrToBuy, int nrToRestock) {

   inventory += nrToRestock - nrToBuy;

   System.out.printf("Inventory: %d bottles.\n", inventory);

 }

}

The program is an illustration of a sequential program, and it does not require loops, iterations and branches.

The program in java, where comments are used to explain each line is as follows:

import java.util.Scanner;

class Main {

public static void main (String args[]){

   //This creates a scanner object

  Scanner input = new Scanner(System.in);

  //This gets input for the number of purchases

  int Purchased = input.nextInt();

  //This gets input for the number of restocks

  int Restock = input.nextInt();

  //This calculates and prints the inventory

System.out.print("Inventory: "+(20 - Purchased + Restock)+" bottles");

}

}

At the end of the program, the net inventory is printed.
