Your answer is outline.

An outline is the tool that will help you the most when developing the content you will use in your presentation.

A presentation is a method of communicating information from a speaker to an audience.

Presentations are usually demonstrations, introductions, lectures, or speeches intended to inform, persuade, inspire, motivate, build goodwill, or introduce a new idea/product.

An outline is a list of the main topics and subtopics that you intend to cover in your presentation in a hierarchical order.

It can assist you in ensuring that your ideas flow logically and that no important points are overlooked.

A storyboard, on the other hand, is a visual representation of your presentation that shows the order of your slides, the images or videos you intend to use, and the text that will go with them.

Thus, the answer is outline.

Which of the following class definition defines a legal abstract class Group of answer choices

(a)

public class Rectangle abstract {

   public abstract double findArea ( );

}

(b)

public abstract class Rectangle {

   public abstract double findArea ( );

}

(c)

public class Rectangle {

   public abstract double findArea ( );

}

(d)

public class abstract Rectangle {

   public abstract double findArea ( );

}

(b)

public abstract class Rectangle {

   public abstract double findArea ( );

}

When a class is declared with the abstract keyword, the class is called an abstract class. Abstract classes cannot be instantiated and may include one or more abstract methods. If a class contains an abstract method, then it (the class) must be declared abstract.

In Java, abstract classes are defined using the following format:

[access_modifier] abstract class [name_of_class]

[access_modifier] specifies the access modifier of the class which could be public, private, e.t.c

abstract is the keyword that specifies that the class is an abstract class.

class is a keyword used for defining classes

name_of_class specifies the name of the class.

The only option that fulfils this format is option b where;

(i) The access modifier is public

(ii) The name of the class is Rectangle

Option a is not correct because the abstract keyword is supposed to come before the class keyword.

Option c is not correct because the keyword abstract is missing. In other words, the class must be declared abstract since it contains abstract method findArea();

Option d is not correct because the abstract keyword is supposed to come before the class keyword.

I wrote my code in python 3.8. I hope this helps.

(a) convert (101011)₂ = ( )₁₀ ?

(b) convert(596)₁₀= ( )₁₆ ?

(c) convert( 101011101)₂ = ( )₁₆ ?

(d) convert(37)₁₀= ( )₂ ?​

(a) (101011)₂ = ( 43)₁₀

(b) (596)₁₀= ( 254)₁₆

(c) ( 101011101)₂ = ( 15D)₁₆

(d) (37)₁₀= ( 100101)₂

(a) convert (101011)₂ = ( )₁₀

This means that (101011)₂ be converted to base 10 (decimal).

To convert from binary to decimal, find the sum of the binary digits times their power of 2. i.e

(101011)₂ = 1 x 2⁵ + 0 x 2⁴ + 1 x 2³ + 0 x 2² + 1 x 2¹ + 1 x 2⁰

(101011)₂ = 1 x 32 + 0 x 16 + 1 x 8 + 0 x 4 + 1 x 2 + 1 x 1

(101011)₂ = 32 + 0 + 8 + 0 + 2 + 1

(101011)₂ = 43₁₀

Therefore, (101011)₂ = ( 43)₁₀

(b) convert(596)₁₀= ( )₁₆

This means that (596)₁₀ be converted to base 16 (hexadecimal).

To convert from decimal to hexadecimal,

i. start by dividing the decimal number by 16 taking note of the result and the remainder.

ii. divide the result obtained in (i) by 16 and take note of the new result and the remainder.

iii. repeat steps i and ii until the result is 0.

iv. the result is a combination of the remainders starting from the last.

16 | 596

16 | 37 r 4

16 | 2 r 5

    | 0 r 2

Now combine the remainders starting from the bottom up. i.e

254₁₆

Therefore, (596)₁₀= ( 254)₁₆

(c) convert ( 101011101)₂ = ( )₁₆

This means that (101011101)₂ be converted to base 16 (hexadecimal).

To convert from binary to hexadecimal,

i. starting from the rightmost bit, group the binary digits into a group of 4 bits as follows

101011101 => 1   0101    1101

ii. the group that does not contain 4 bits is padded with 0s

101011101 => 0001   0101    1101

iii. using the hexadecimal table, convert each group to hexadecimal as follows.

0001 = 1

0101 = 5

1101 = D

iv. combine the result

15D

Therefore, ( 101011101)₂ = ( 15D)₁₆

(d)  convert(37)₁₀= ( )₂

This means that (37)₁₀ be converted to base 2 (binary).

To convert from decimal to binary,

i. start by dividing the decimal number by 2 taking note of the result and the remainder.

ii. divide the result obtained in (i) by 2 and take note of the new result and the remainder.

iii. repeat steps i and ii until the result is 0.

iv. the result is a combination of the remainders starting from the last.

2 | 37

2 | 18 r 1

2 | 9 r 0

2 | 4 r 1

2 | 2 r 0

2 | 1 r 0

  | 0 r 1

Now combine the remainders starting from the bottom up. i.e

100101₂

Therefore, (37)₁₀= ( 100101)₂

The program in Java is as follows:

import java.util.Scanner;

public class Main{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 double n1, n2;

 n1 = input.nextDouble();

 n2 = input.nextDouble();

 double Max = Math.max(n1,n2);

 double Min = Math.min(n1,n2);

 System.out.println("Max: "+Max);

 System.out.println("Min: "+Min); }}

Explanation:

This declares the numbers

 double n1, n2;

This gets input for n1

 n1 = input.nextDouble();

This gets input for n2

 n2 = input.nextDouble();

This gets the max of both using the max function

 double Max = Math.max(n1,n2);

This gets the min of both using the min function

 double Min = Math.min(n1,n2);

This prints the max

 System.out.println("Max: "+Max);

This prints the min

 System.out.println("Min: "+Min);

Spelling

Word processors contain an electronic spell checker. The student writer has immediate feedback about misspelled words. Student must discern which of the computer-generated spellings is correct for the context. Teachers no longer have to red-ink spelling errors. They can focus on the few exceptions the spellchecker does not catch.

Security

Teachers and students gain a sense of security about losing assignments. When the student saves her work, she avoids the possibility of the assignment being lost or misplaced. If an assignment is ever misplaced, a replacement can be easily printed.

Legibility

Teachers benefit by receiving a readable copy that is easy to grade. Students with poor handwriting can increase their scores with better looking papers. Students should be instructed to turn in copies of work in a readable font.

Publishing

Work done on a word processor can easily published on a bulletin board. Teachers can create electronic anthologies of their students' writings. Each student can receive an electronic copy of published works with no printing costs.

Mobility

Work done on a word processor and saved on the Internet is highly portable and accessible from any computer with Internet access. Dogs do not eat papers in cyberspace. "I forgot it at home" is irrelevant. Just log onto the nearest computer and your work appears on the screen.

The following fix were made to the program

Explanation:

(1) void main implies that the main function will not return any value. So, you change it to int main() and then set the return value

(2) There is no need to pause the program, so system.("pause") is not necessary.

(3) The question says there are 5 candidates. So, we set the arrays to accommodate inputs for 5 values

(4) percent array is declared as float; 100.0 will ensure that it calculates the percentage as a float value.

Explanation:

Answer:

C and B in that order

Explanation:

Answer:

import java.util.ArrayList;

import java.util.Collections;

public class MyArrayList<T> extends ArrayList<T> {

 public boolean add(T obj) {

   if (Collections.frequency(this, obj) < 2) {

     return super.add(obj);

   }

   return false;

 }

}

Explanation:

According to the requirement, an element with the same value can occur at most twice in the list.

The Collections.frequency utility is useful to count the occurrances.

Sure, here's an implementation of the `MyArrayList` class that extends `java.util.ArrayList` and overrides the `add` method as described:

```java

import java.util.ArrayList;

import java.util.HashMap;

import java.util.Map;

public class MyArrayList<E> extends ArrayList<E> {

   "ATTHERATE"Override

   public boolean add(E obj) {

       // Count occurrences of each element in the list

       Map<E, Integer> countMap = new HashMap<>();

       for (E element : this) {

           countMap.put(element, countMap.getOrDefault(element, 0) + 1);

       }

       // Check if obj occurs in the list only once or not at all

       if (!countMap.containsKey(obj) || countMap.get(obj) == 1) {

           return super.add(obj);

       }

       // If obj occurs more than once, do nothing

       return false;

   }

}

```

In this implementation, the `add` method first counts the occurrences of each element in the list using a `HashMap`.

Then, it checks whether the given object `obj` occurs only once or not at all in the list. If so, it adds the object to the list using the `super.add(obj)` call.

If `obj` occurs more than once, the method does nothing by returning `false`. This way, the `MyArrayList` class ensures that duplicates are added only once, or not at all, as required.
