Explanation:
The following method is intended to remove all values from the ArrayList a that have the same value as val; however, this method does not work correctly.public void removeValue(ArrayList a, int val) {int i;for (i = 0; i < a.size(); i++) {if (a.get(i) == val) {a.remove(i);}}}If the a contains 2 3 4 3 3 4 4 5 4 3 2 1 and val is equal to 4, then a should contain 2 3 3 3 5 3 2 1 after removeValue is invoked. What does a actually contain after removeValue is invoked? (2 points)1) 2 3 3 4 4 5 4 3 2 12) 2 3 3 3 4 5 3 2 13) 2 4 3 4 5 4 2 14) 2 3 3 3 5 3 2 15) 2 4 3 4 4 5 3 2 1
Answer:
ArrayList a contains [2, 3, 3, 3, 4, 5, 3, 2, 1]
Explanation:
Given
The removeValue method
Required
The content of ArrayList a, after the method is called
From the question, we understand that arraylist a is:
[tex]a= [2, 3, 4, 3, 3, 4, 4, 5, 4, 3, 2, 1][/tex]
[tex]val =4[/tex]
The function fails when the value to be removed appear consecutively in the list.
4 appears in index 5 and 6 of the list. Only one of the 4's will be removed
So, the updated list will be: [2, 3, 3, 3, 4, 5, 3, 2, 1]
Insert XXX to output the student's ID. public class Student { private double myGPA; private int myID; public getID) { return myID; public static void main(String [] args) { Student s = new Studento; XXX System.out.println("Student ID: "); System.out.println("Student ID:" + getID()); System.out.println("Student ID:" + s.getId()); System.out.println("Student ID:" + student.getID()); A static main() _ has direct access to class instance members can declare and create objects can call instance methods without an object O can not be included within a programmer-defined class What is stored in score1, score2, and grade? Integer scorel = 72; int score2 = 85; Character grade = 'C'; obj reference, 85, obj reference 72,85, obj reference, obj reference, obj reference obj reference, obj reference, Which is true? Instances of programmer-defined objects are immutable Contents of a Double instance can be modified after initialization An instance of String stores data rather than an object reference Reference variables store memory locations
Answer:
Explanation:
The question above is missing many details and are actually various questions in one. I will answer each one seperately below...
A. The piece of code to get the ID in this code snippet that needs to replace XXX would be the following ... System.out.println("Student ID: " + s.getID());
B. A static main() can declare and create objects. Once these objects are created their instance methods can then be called.
C. Integer score1 = 72;
int score2 = 85;
Character grade = 'C';
In the above code snippet, the information stored in score1, score2, and grade are the following... obj reference, 85, obj reference. This is becasue both Integer and Character are classes and the values being passed to their variables are referencing that object class, while score2 is a primitive type of int and is therefore simply a number.
D. The statement that is true is ... Contents of a Double instance can be modified after initialization. Objects can be modified by calling its setter methods after initializing it.

public class Example {
private int x;
// Constructor not shown.
}
Which of the following is a correct header for a method of the Example class that would return the value of the private instance variable x so that it can be used in a class other than Example ?
private int getX()
private void getX()
public int getX()
public void getX()
public void getX(int x)
Answer:
public int getX()
Explanation:
From the question, we understand that the value is to be accessed in other classes.
This implies that we make use of the public access modifier. Using the public modifier will let the instance variable be accessed from other classes.
Also, we understand the return type must be the variable type of x. x is defined as integer. So, the constructor becomes public x
Lastly, we include the constructor name; i.e. getX().
Hence, the constructor is: public int getX()

My father helps me more than helping my sister in Maths because I need more help to understand. This situation shows equality. Hence, option A is correct.
What is equality?Ensuring that each person has an equal chance to maximize their potential is what equality is all about. It is also the idea that no one should have worse life opportunities due to their birth circumstances, place of origin, religious beliefs, or physical or mental limitations.
Different thinkers and ideologies have emphasized the three primary components of equality, namely political, social, and economic, while highlighting the numerous types of inequalities that exist in society.
"The state or quality of being equal; correspondence in number, degree, value, rank, or skill" is how the term equality is defined. Page 3 3 The concept of equality is typically straightforward: three buckets that each contain five apples are considered to be equal.
Thus, option A is correct.

Answer: 999999
Explanation: Last summer, my family and I took a trip to Jamaica. My favorite part of the trip was when we went to a place called the Luminous Lagoon. We ate dinner and waited for the sun to go down. Then we boarded a boat and went out into the lagoon. That’s when the magic started.
At first we could not see very much in the darkness except for the stars in the sky. After a few minutes, however, I noticed some fish swimming in the water. They didn’t look like ordinary fish. These fish were glowing! Our guide explained that the glow came from tiny creatures in the water called dinoflagellates. These little animals are not visible to us, but their bodies produce light using something called bioluminescence, just like fireflies. There are so many of these creatures in Luminous Lagoon that the water around them seems to glow.
After our guide explained these facts to us, he told us to put our hands in the water. I was not sure if it would work, but I tried it. When I did, my hand looked like it belonged to a superhero! It was glowing bright blue. I hope someday I get to return to the Luminous Lagoon. The lights in the water were much more entertaining than the ones in the sky.

The Uniform Electronic Transmission Act (UETA) a. declares that e-signatures are invalid. b. has only been adopted in a handful of states. c. creates a safe cyberspace environment in which business communications cannot be intercepted or fraudulently altered. d. declares that a contract or signature may not be denied enforceability just because it is in electronic form.
Answer:
d. declares that a contract or signature may not be denied enforceability just because it is in electronic form.
Explanation:
The Uniform Electronic Transmission Act (UETA) is one of the Uniform Acts and key laws of the United States of America. This Act was proposed by the National Conference of Commissioners on Uniform State Laws (NCCUSL) and has since been adopted by forty eight (48) states including the U.S Virgin Islands and the District of Colombia.
However, New York and Illinois have not adopted UETA but they have similar state legislations and laws that recognizes electronic signatures.
The main purpose of UETA is to give legal validity to electronic signatures, electronic contracts and the harmonization of laws regarding the retention of paper records such as checks across the United States of America.
Hence, the function of UETA is to create unison or harmony between the laws regarding records in paper format and the authenticity of electronic signatures.
An electronic signature can be defined as an electronic data such as symbols, signs or sound which are attached to purchase order, contracts or any other contractual agreements adopted by an individual as an agreement to the deal.
According to the Uniform Electronic Transmission Act (UETA), an electronic contract or signature may not be denied enforceability just because it is in electronic form.
In conclusion, both the electronic version of a contract and signature are valid, legal and enforceable across states where they are recognized in the United States of America.

Write a program that does the following: - Ask user to input lengths of three sides. - Classify it into one of the following: o Equilateral triangle o Isosceles right triangle o Isosceles triangle that is not a right triangle o A triangle that is not an isosceles and not an equilateral For example, an execution could look like
Answer:
You did not specify which programming language you use, but you can use if statements to check each using the sides.
- A triangle is equilateral when all the 3 sides are equal. (a = b = c)
- A triangle is isoscles when two of the sides are equal (a = b or b = c or c = a)
- A triangle is right when square of side C is equal to the sum of the squares of the other two sides. (c^2 = a^2 + b^2)
- For the last classification you can use "else"
If you noticed, the condition to have an isosceles triangle is repeated for two of the tasks so we can use the same if statement to check if the triangle is isosceles right or just isoscles with two built-in if statements (if and else)- if it's right then it's isosceles right else it's just isosceles.
And else statement for the last task.
Example code structure:
If triangle is Equilateral then
- Equilateral Triangle
end
If triangle is Isoscles then
if triangle is right then
- Isoscles Right Triangle
end
else (the triangle is not right)
- Isoscles Triangle
end
end
else (the triangle is not Equilateral nor Isoscles)
- Triangle that is not isoscles nor equilateral.
end
Explanation:
Here is a code example with java, I hope it helps, although it might not be the programming language you use:
import java.util.Scanner;
public class Triangle {
public static void main(String[] args) {
Scanner input = new
Scanner(System.in);

A capacitor of capacitance 102/π µF is connected across a 220 V, 50 Hz A.C. mains. Calculate the capacitive reactance, RMS value of current and write down the equations of voltage and current.
Answer:
The capacitive reactance will be "100Ω" and RMS value of current is "2.2 A". A further explanation is provided below.
Explanation:
Given:
[tex]C =\frac{10^2}{\pi}\times 10^{-6} \ F[/tex]
[tex]V_{RMS}=220 \ V[/tex]
[tex]f = 50 \ Hz[/tex]
Now,
The capacitive reactance will be:
⇒ [tex]X_c=\frac{1}{\omega C} =\frac{1}{2 \pi f C}[/tex]
[tex]=\frac{1}{2\times \pi\times 50\times \frac{10^{-4}}{\pi} }[/tex]
[tex]=100 \ \Omega[/tex]
RMS value of current will be:
⇒ [tex]I_{RMS}=\frac{V_{RMS}}{X_c}[/tex]
[tex]=\frac{220}{100}[/tex]
[tex]=2.2 \ A[/tex]
So that,
⇒ [tex]V_m=220\times \sqrt{2}[/tex]
[tex]=311 \ V[/tex]
⇒ [tex]I_m=2.2\times \sqrt{2}[/tex]
[tex]=3.1 \ A[/tex]
hence,
The equation will be:
⇒ [tex]\nu=311 sin31 \ 4t[/tex]
and,
⇒ [tex]i=3.1 sin(314t+\frac{\pi}{2} )[/tex]

Suppose your training examples are sentences (sequences of words). Which of the following refers to the j^th word in the i^th training example?
We index into the ith row first to get ith the training example (represented by parentheses), then the column to get jth the word (represented by the brackets).
a. x^(j)
b. x^(j)
c. x^(i)
Answer:
a. x^<i>(j)
Explanation:
The solution has been explained in the question; however, I will provide further explanation.
The sequence to access a word is:
Training example --> Word
In other words, you first access the training example, before you gain access to the word being searched for.
Rewrite the following:
Training example --> Word
as:
ith training example --> jth word
Hence, the representation is:
[tex]x^{(i)<j>[/tex]
Writing of a program to take two integer and print sum and product of them.

Take two double input for length and breadth of a rectangle and print area type casted to integer.
Take side of a square from user and print area and perimeter of it.
Answer:
1.)
def two(a, b) :
print(a+b)
print(a*b)
2.)
a = int(input('enter an integer values '))
b = int(input('Enter another integer value' ))
print(a+b)
print(a*b)
3.)
Take side of a square from user and print area and perimeter of it.
def square(a):
area = a**2
perimeter = 4*a
print(area, perimeter)
Explanation:
Code written in python :
The first function named two, takes to arguments a and b ;
The sum of integers a and b is taken and displayed using ; print(a+b)
The product of integers a and b is taken and displayed using ; print(a*b)
2.)
User can enter an input and converted to an integer value using the command ;
int(input()) ; the sum and product of these values are displayed using :
print(a*b) and print(a+b)
The Area and perimeter of a square requires the side length, which is taken as the argument a in the square function defined.
Area of square = a² = a**2
Perimeter = 4 * a
Create a method called randomValues that uses a while loop to generate a random number between 1-25 until the value 10 is generated. Therefore, 10 will be the value that stops your loop from generating a random number.
Answer:
The method in Java is as follows:
public static void randomValues(){
Random r = new Random();
int sentinel = 10;
int randNum = r.nextInt(24) + 1;
while(randNum!=sentinel){
System.out.print(randNum+" ");
randNum = r.nextInt(24) + 1;
}
System.out.print(sentinel);
}
Explanation:
This defines the method
public static void randomValues(){
This creates a random object, r
Random r = new Random();
This sets the sentinel value to 0
int sentinel = 10;
This generates a random number
int randNum = r.nextInt(24) + 1;
This loop is repeated until the the random number is 10
while(randNum!=sentinel){
Print the generated number
System.out.print(randNum+" ");
Generated another random number
randNum = r.nextInt(24) + 1; }
Print the sentinel (i.e. 10)
System.out.print(sentinel);
}

Computer is an example of electronic device.
You are working on a graphical app, which includes multiple different shapes. The given code declares a base Shape class with an abstract area() method and a width attribute. You need to create two Shape subclasses, Square and Circle, which initialize the width attribute using their constructor, and define their area() methods. The area() for the Square class should output the area of the square (the square of the width), while for the Circle, it should output the area of the given circle (PI*width*width). The code in main creates two objects with the given user input and calls the area() methods.
Sample Input:
5
2
Sample Output:
25
12.566370614359172
The area of the square is 5*5=25, while the area of the circle is PI*2*2=12.566370614359172
A class can have multiple subclasses, where each of the subclasses function independently. The extend keyword will be used to pass attributes from the Shape class to the Square and Circle subclasses
To answer this question, I will make the following assumptions
The Shape class is already definedThe area() method of the Shape class is also definedLines that begin with // are comments, and these lines will be used to explain the code segment
//This creates the Square class
class Square extends Shape {
//The creates a constructor for width variable
Square(int length) { this.width = length; }
//This defines the area() method from the Square class
void area() {
//This calculates and prints the area of the square
System.out.print(Math.pow(width,2)); } }
//This creates the Circle class
class Circle extends Shape {
//The creates a constructor for width variable
Circle(int radius){ this.width = radius; }
//This defines the area() method from the Square class
void area(){
//This calculates and prints the area of the circle
System.out.println(Math.PI*Math.pow(width,2));
} }

The device which superimposes information onto a high frequency signal for transmission is called: a modulator a demodulator the carrier the intelligence
Answer:
a modulator
Explanation:
Modulation can be defined as the conversion of digital signals into an analogue signal while transmitting it over a line. Similarly, demodulation is the conversion of analogue signal into a digital signal.
AM is an acronym for Amplitude Modulation and it's refers to a process that is typically used for coding sounds such as voices and music for transmission from one point to another.
On the other hand, FM is an acronym for frequency modulation used for the propagation and transmission of sound waves.
Basically, these two forms of modulation are used for broadcasting in radio transmission.
In Radio transmission, a modulator is an electronic device that is designed to superimpose a low frequency information onto a high frequency signal for transmission. Also, the high frequency is typically the carrier in the radio transmission process.
