   VendingMachine machine = new VendingMachine(20);

   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.

Answer:

(a): The value of the objective function at the corner points

[tex]Z = 10[/tex]

[tex]Z = 19[/tex]

[tex]Z = 15[/tex]

(b) The optimal solution is [tex](6,2)[/tex]

Explanation:

Given

[tex]Min\ Z = X_1 + 2X_2[/tex]

Subject to:

[tex]-2X_1 + 5X_2 \ge -2[/tex] ---- 1

[tex]X_1 + 4X_2 \le 27[/tex] ---- 2

[tex]8X_1 + 5X_2 \ge 58[/tex] --- 3

Solving (a): The value of the at the corner points

From the graph, the corner points are:

[tex](6,2)\ \ \ \ \ \ (11,4)\ \ \ \ \ \ \ \ (3,6)[/tex]

So, we have:

[tex](6,2)[/tex] ------- Corner point 1

[tex]Min\ Z = X_1 + 2X_2[/tex]

[tex]Z = 6 + 2 * 2[/tex]

[tex]Z = 6 + 4[/tex]

[tex]Z = 10[/tex]

[tex](11,4)[/tex] ------ Corner point 2

[tex]Min\ Z = X_1 + 2X_2[/tex]

[tex]Z = 11 + 2 * 4[/tex]

[tex]Z = 11 + 8[/tex]

[tex]Z = 19[/tex]

[tex](3,6)[/tex] --- Corner point 3

[tex]Min\ Z = X_1 + 2X_2[/tex]

[tex]Z = 3 + 2 * 6[/tex]

[tex]Z = 3 + 12[/tex]

[tex]Z = 15[/tex]

Solving (b): The optimal solution

Since we are to minimize Z, the optimal solution is at the corner point that gives the least value

In (a), the least value of Z is: [tex]Z = 10[/tex]

So, the optimal solution is at: corner point 1

[tex](6,2)[/tex]

Answer:

The illustration in Java is as follows:

import java.util.*;

import java.lang.Math.*;

class Main{

public static void main (String[] args){

 Scanner input = new Scanner(System.in);

 double num, root, temp;

 num = input.nextDouble();

 temp = num;

 while (true){

  root = 0.5 * ( (num / temp)+temp);

  if (Math.abs(root - temp) < 0.00001){

   break;   }

  temp = root;  }

 System.out.println("Root: "+root);

}}

Explanation:

This declares all necessary variables

 double num, root, temp;

This gets input for num (i.e the number whose square root is to be calculated)

 num = input.nextDouble();

This saves the input number to temp

 temp = num;

This loop is repeated until it is exited from within the loop

 while (true){

Calculate temporary square root

  root = 0.5 * ( (num / temp)+temp);

The loop is exited, if the absolute difference between the root and temp is less than 0.00001

  if (Math.abs(root - temp) < 0.00001){

   break;   }

Save the calculated root to temp

  temp = root;  }

This prints the calculated root

 System.out.println("Root: "+root);

1. Secure drinkable water

2. Promote organic products through the provision of subsidiaries

3. Create a place for bioproducts to be sold

Explanation:

Without the use of pesticides and chemical products, organic farming does not toxic residues poison land, water, and air. Sustainable land and resource use in organic farming. Crop rotation promotes healthy and fertile soil.

In conventional farming, the use of pesticides contaminates runoff, which is a natural part of the water cycle. In groundwater, surface water, and rainfall, pesticide residues are found. This means that in food produced with pesticides, contamination may not be isolated, but also affect the environment.

Create a place for bioproducts to be sold

Biologics offer farmers, shippers, food processors, food retailers, and consumers a wide range of benefits. Biocontrols can also help protect the turf, ornamentals, and forests in addition to food use. They can also be used for disease and harm controls in public health, i.e., mosquitoes and the control of ticks.

The benefits of the use of biologicals in farming applications tend to be more direct, though they are indirect. The list includes benefits to crop quality and yield which help farmers supply consumer products worldwide with healthy and affordable fruit and vegetables. Biocontrols also allow farmers in their fields to maintain positive populations of insects (natural predators) through their highly-target modes of action, reducing their reliance on conventional chemical pesticides.

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.

   {

       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:

[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]

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 immaterial benefits stem from the development of an information system and cannot easily be measured in dollars or with confidence. Potential intangible advantages include a competitive need, timely information, improved planning and increased flexibility in organisation.

Explanation:

Intangible advantages

Lower productivity and the lack of 'think outside' employees and managers as well as greater sales include the intangible costs of such an operational environment. All these factors improve when employees spend less of their time in addressing current methods of operation and are concerned about whether they will have a job or an employer in six months or a year. The automation level envisaged in this new system should enhance the overall efficiency of management. The operative controls and design functions should be simplified by tight system integrations with accessible automated database sources. However, it is difficult to describe the exact form of these simplifications.

Tangible costs of the new system include costs of analysis, design and construction of the system, such as the recruitment of contractors or new employees, and the assignment of existing staff. Also consideration shall be given to hardware, software purchased and operating costs. Intangible costs include disturbances to the current activities caused by development and deployment and potential adverse effects on the morals of employees.

While the new system may feel good in the long term, short-term stress and other negative consequences will still be present. In the way that Reliable does virtually everything, the system is the focus of a major change. An organisation's monumental change has widespread negative effects on operations and employees.
