Draw an ERD for the following problem with attributes, primary keys, cardinalities and participation constraints and specialization, if appropriate.
An information studies student wants to keep track of the following information. A publishers publishes two kinds of publications: books and journals. Any one publisher publishes at least one book and/or at least one journal. Each book can be written by one or more authors and one author can write one or more books. Each book and journal is characterized by one or more indexed keywords, which are represented by a keyword number and keyword. Not every keyword is used by the journals, however. Both books and journals have a unique number (such as ISBN# for a book and ISSN# for a journal), title and a publisher. For books, the student tracks the published year, all author information and their institutions. For journals, the student keeps the starting year first published, the number of issues to be published per year and the category of the journal (such as academic, newsletter, trade). Each publisher has name, address and phone.Each author has an ID number, name, address, phone, author's affiliated institution and the address of the institution. An author may be affiliated with more than one institution.The student would like to keep only authors who are participating in writing at least one book and institutions that have such authors.

Answer:

Explanation:

The following code is written in Java. It creates the Rectangle class with the height and width variables. The constructor takes these variables as parameters to create Rectangle objects. It creates the get_perimeter method that sums up two of each side in order to get the perimeter of the Rectangle. A get_area method multiplies the height by the width to get the area. Finally, a resize method takes in a double factor variable and multiplies the height and the width by the factor to get a resized Rectangle object.

class Rectangle {

   double height, width;

   public Rectangle(double height, double width) {

       this.height = height;

       this.width = width;

   }

   public double get_perimeter() {

       return (this.height + this.height + this.width + this.width);

   }

   public double get_area() {

       return (this.height * this.width);

   }

   public void resize(double factor) {

       this.height *= factor;

       this.width *= factor;

   }

}

Answer:

#include <stdio.h>

#include <string.h>

void main( )

{

array flowerProp[2];

FILE *fp; // file pointer

char flower[255]; // creating a char array to store data

fp = fopen("flowers.dat","r");

if (fp == NULL){

   printf("File flower.dat does not exist");

   return;

}

// assuming the growing condition is next line to the flower name.

while(fscanf(fp, "%s", flower)!=EOF){

   flowerProp.push(flower);

   if (flowerProp.length == 2){

       printf("%s: %s\n ", flowerProp[0], flowerProp[1]);

       memset(flowerProp, 0,0);

   }

}    

fclose (fp );

}

Explanation:

The algorithm creates a pointer to the memory location to the file starting position, the character size is used to get a string from the file line by line. Then it opens and checks if the file exists.

If the file exists, the while gets the name and growth condition of the flower, saves it to an array, prints the name and condition, and clears the array for the next flower type in the loop.

Answer:

Network Segmentation

Explanation:

The best technology to implement in this scenario would be Network Segmentation. This allows you to divide a network into various different segments or subnets. Therefore, this allows you to isolate the remediation network from the secure network since each individual subnet that is created acts as its own network. This also allows you to individually implement policies to each one so that not every network has the same access or permissions to specific data, traffic, speeds, etc. This would solve the issues that you are having and add multiple benefits.

Answer: C. All dog breeds that weigh less than 50 pounds have a maximum lifespan of more than 10 years.

Explanation:

Looking at the scatter plot, it is shown that all dogs that weigh less than 50 pounds have a maximum lifespan that is above 10 years with a number of them even approaching 20 years.

This means that on average, dogs that weigh less tend to live longer than dogs that weigh more which as shown in the scatter plot have a lower lifespan the heavier they are.

Answer:

The mechanical advantage is 0.25

This mechanical advantage shows that the force at which the deodorant sprays is the quarter of the applied effort, and hence the efficiency of your finger as a machine is 25%.

Explanation:

Given;

output force, F₂ = 15 N

input force, F₁ = 60 N

Mechanical advantage also known as force ratio is defined as the ratio of the output force (load) to the ratio of input force (effort).

[tex]M.A = \frac{0utput \ Force}{1nput \ Force} \\\\M.A = \frac{15 \ N}{60 \ N} \\\\M.A = 0.25[/tex]

This shows that the force at which the deodorant sprays is the quarter of the applied effort, and hence the efficiency of your finger as a machine is 25%.

Answer: D

Explanation:

It is not A or C because the "d" in "Divide" is capitalized and the d is lowercase in calling the function. Therefore the answer is D (the last choice) because numA / numB (30 / 5) equals 6.

The major portion of the program has a line of code. The functions that find the quotient of 30 and 5 and returns 6 is as follows:-

def divide(numA, numB)

: return numA/numB

Thus, option D is correct.

A computer program is a collection of instructions written in a programming language that a computer can execute. Software contains computer programs as well as documentation and other immaterial components. Source code refers to a computer system in its human-readable form.

Source lines of code, often known as lines of code, is an algorithm computes that counts the number of lines in the text of a computer program's source code to determine the size of the program.

It is not A or C since the "d" in "Divide" is uppercase, but the d in invoking the function is lowercase. As a result, D (the last option) is the correct solution, since numA / numB (30 / 5) = 6. Therefore, it can be concluded that option D is correct.

Answer: D. Multiply the number of microseconds by 1,000.

Explanation:

In order to convert microseconds to nanoseconds, it should be noted that one should multiply the number of microseconds by 1,000.

For example, if we want to convert 12 microseconds to nanoseconds. This will be:

= 12 × 1000

= 12000 nanoseconds.

Therefore, with regards to the information given above, the correct option is D.

Answer:

Place the modules in the appropriate slots on the motherboard.

Explanation:

You must install memory in the correct slots to use dual-channel memory. The two slots may be next to one other or alternate depending on the motherboard. For the correct configuration, consult the motherboard manual. Dual-channel support is primarily determined by the motherboard (e.g., the memory controller), rather than the memory. With Rambus RAM, continuity modules are employed; if they were necessary on this system, none of the memory would have been identified. Memory timing is based on the CAS latency. If the system is unstable with the current memory timing settings, you may want to change the timing.

Answer:

file = open('My_data.txt', 'w')

file.write('This file contains data')

Explanation:

Required

The correct syntax to write to file

From the question, we understand that we are to write to file and not append to the file.

This implies that the access mode will be w which stands for write

The first line of (a), (b) and (c) is correct.

(d) is incorrect

Solving further,

Only values of type string (i.e. str) can be written to file

With this, we can conclude that:

(a) is correct because 'This file contains data' is of type string

(b) and (c) are incorrect because, in (b), the value is of type integer and in (c), the type is list

So a output device is anything that can output info from the computer so

we are read and understand it some are a printer monitor and soundboard

Answer:

The method in java is as follows:

   public static int power(int num, int exp){

       if(exp == 0){            return 1;        }

       if(exp < 0){

           throw new IllegalArgumentException("Positive exponents only");        }

       else{            return (num*power(num, exp-1));        }

   }

Where

[tex]num\to[/tex] base

[tex]exp \to[/tex] exponent

Explanation:

This defines the method

   public static int power(int num, int exp){

This represents the base case, where the exponent is 0

       if(exp == 0){

If yes, the function returns 1

           return 1;        }

If exponent is negative, this throws illegal argument exception

       if(exp < 0){

           throw new IllegalArgumentException("Positive exponents only");        }

If exponents is positive, this calls the function recursively

       else{            return (num*power(num, exp-1));        }

   }
