In 2-3 sentences, describe one way business professionals use a spreadsheet to complete a task.

Answer:

The correction is as follows:

(a)

small = arr[0];

for (int j = 0; j < arr.length; j++){

if (small > arr[j]) {

small = arr[j];      }  }

(b)

double sum = 0;

int n = arr.length;

for (int k = arr.length-1; k >= 0; k--)

sum = sum + arr[k];  

double avg = sum /n;

(c)

int[] a = {1,2,3,4,5};

int[] b = new int[5];

for (int i=0; i<a.length; i++)

b[i] = a[a.length-i-1];

Explanation:

Required

Correct each of the given code

a.

This line is correct; it initializes the smallest to the first element

small = arr[0];

This iterates through the array; however, the last element is left out.

for (int j = 0; j < arr.length-1; j++)

So, the correct code is: for (int j = 0; j < arr.length; j++){

The expected remaining part of the program which compares the elements of the array is missing

I've completed the code [See the answer section]

b.

By syntax this line is correct. However, for the average to be calculated as double; sum has to be declared as double

int sum = 0;

So, the correct code is: double sum = 0;

This line correctly calculates the length of the array

int n = arr.length;

This iteration will create an endless loop

for (int k = arr.length; k <= 0; k--)

So, the correct code is: for (int k = arr.length-1; k >= 0; k--)

This correctly add up the elements of the array

sum = sum + arr[k];

This correctly calculate the average of the array elements

double avg = sum /n;

(c)

The array a is incorrectly initialized because there is no matching end curly brace

int[] a = {1,2,3,4,5);

So, the correct code is: int[] a = {1,2,3,4,5};

This correctly create array b with 5 elements

int[] b = new int[5];

This iterates through a; however, the last element is left out

for (int i=0; i<=a.length; i++)

So, the correct code is: for (int i=0; i<a.length; i++)

This will create an out of bound error

b[i-1] = a[a.length-i];

So, the correct code is: b[i] = a[a.length-i-1];

The program that has the following functions is given below:

#include <algorithm>

int* ShiftByOne(int array[], int size) {

   int temp = array[size - 1];

   for (int i = size - 1; i > 0; i--) {

       array[i] = array[i - 1];

   }

   array[0] = temp;

   return array;

}

int* GetMax(int array[], int size) {

   int max_val = *std::max_element(array, array + size);

   return &max_val;

}

unsigned int GetSize(char str[]) {

   unsigned int size = 0;

   for (int i = 0; str[i] != '\0'; i++) {

      size++;

   }

   return size;

}

Note: The function ShiftByOne() modifies the input array in place and return a pointer to the input array.

The function GetMax() returns the memory address of the maximum value found in the array.

The function GetSize() returns the size of the array.

Question:

Which of the following statements is not a true statement about software architecture?

Answer:

b.) Software architecture dictates the process used by a team to develop use cases for a software system.

Explanation:

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are six (6) main stages in the creation of a software and these are;

1. Planning.

2. Analysis.

3. Design.

4. Development (coding).

5. Deployment.

6. Maintenance.

One of the most important steps in the software development life cycle (SDLC) is design. It is the third step of SDLC and comes immediately after the analysis stage.

Basically, method design is the stage where the software developer describes the features, architecture and functions of the proposed solution in accordance with a standard.

Software architecture can be defined as the software blueprint or infrastructure in which the components (elements) of the software providing user functionality and their relationships are defined, deployed and executed. Thus, it is a structured framework used by software developers to model software components (elements), properties and relationships in order to have a good understanding of how the program would behave.

In conclusion, software architecture doesn't dictate the process used by a team to develop use cases for a software system.

Answer:

Control unit.

Explanation:

A scheduling computer system refers to an ability of the computer that typically allows one process to use the central processing unit (CPU) while another process is waiting for input-output (I/O), thus making a complete usage of any lost central processing unit (CPU) cycles in order to prevent redundancy.

Modern central processing units (CPUs) only require a few nanoseconds to execute any instruction when all operands are stored in its registers.

In terms of the scheduling metrics of a central processing unit (CPU), the time at which a job completes or is executed minus the time at which the job arrived in the system is known as turnaround time.

Generally, it is one of the scheduling metrics to select for optimum performance of the central processing unit (CPU).

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 how to respond to informations sent to the processor.

Answer:

1) 2 bits 2) shown in explanation 3) shown in explanation 4) 22 bits per pixel (2.75 bytes)

Explanation:

As a bit is one of two states, 1 or 0, 2 bits is sufficient to represent 4 colors:

00 = color 1

01 = color 2,

10 = color 3,

11 = color 4

This would be the custom type of encoding for that specific image as it only uses 4 colors.

Now to calculate the amount of memory saved, which is quite simple:

24-2=22

So you Would save 22 bits per pixel or 2.75 bytes per pixel.

RGB is a colour complementary wherein the main light colors of red, green, and blue are coupled in distinct ways of representing a range of colors. It uses to design is named again for preliminary colors red, blue and green of 3 primary additive color schemes.

Following are the solution to the given question:

          [tex]\bold{= \log_2\ \text{(total number of colors)}}\\\\\bold{= \log_2\ (4)}\\\\\bold{= 2}[/tex]

             [tex]\to \bold{ Black = 00}\\\\\to \bold{White= 01}\\\\\to \bold{Red= 10}\\\\\to \bold{Blue= 11}\\[/tex]

              [tex]\to \bold{= (17 \times 20) \times 24} \ \bold{= 8160}[/tex]  

          The number of total bits for the picture now is custom encoded                                  

            [tex]\to \bold{= (17 \times 20) \times 2} \ \bold{= 680}[/tex]

            Calculating the percentage:

               [tex]\bold{= \frac{\text{(original bits - new bits)} \times 100}{\text{original bits}}}\\\\\bold{= \frac{(8160 - 680) \times 100}{8160}}\\\\\bold{= \frac{7480 \times 100}{8160}}\\\\\bold{= \frac{748000}{8160}}\\\\\bold{= 91.67\%}[/tex]

So, the final answer is "2,00,01,10,11, and 91.67%"

D) by preventing access by more than one person at a time

Networks use authentication and authorization to control access to data. They require that a person entering the network has valid credentials, such as a username and password, before they can access any data on the network. Once the credentials have been provided and verified, the user is typically given limited access to the data that is based on authorization rules set up within the network. This helps ensure that data is securely accessed by only those users that need to access it, preventing unauthorized access by multiple persons at once.

Below is a simple flowchart that shows the process of calculating the volume of an object using its mass and density:

       +-----------------------------+

       |     Input: Mass (m),        |

       |     Density (d)             |

       +-----------------------------+

                |

                |

       +-----------------------------+

       |   Volume = Mass / Density   |

       +-----------------------------+

                |

                |

       +-----------------------------+

       |    Output: Volume (v)       |

       +-----------------------------+

The flowchart I provided shows the basic process of calculating the volume of an object using its mass and density. The process starts with the input of the object's mass and density. The mass is typically given in grams and the density is given in grams per cubic centimeter.

The next step is to calculate the volume of the object. This is done by using the formula for density, which states that density is equal to mass divided by volume. So, to find the volume, we divide the mass of the object (in grams) by its density (in grams per cubic centimeter). This formula can be written as:

volume = mass / density

Finally, the calculated volume is then output, which is typically given in cubic centimeters.

Note that:

density = mass/volume.

Density = mass / volume

Explanation:

In order to get a O(log n) time complexity, a recursive procedure is implemented by the algorithm

The algorithm begins here

Exponent(x, n):

If n is 0, the procedure returns 1

if(n == 0):  

    return 1

This recursively calculates the product of x, n/2 times

pr= Exponent(x, int(n / 2))

If n is even, the square of prod (above) is calculated  

if (n % 2 == 0):

 Return pr* pr

If otherwise (i.e. odd)

else:

If n is above 0, the square of prod multiplied by x is calculated

 if(n > 0):  

     Return x * pr* pr

If otherwise, the square of prod divide by x is calculated

 else:
