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.
Write a program that will: 1. Call a function to input temperatures for consecutive days in an array. The temperatures are to be integer numbers. 2. The user will input the number of temperatures. There will be no more than 10 temperatures. 3. Call a function to sort the array by ascending order. You can use any sorting algorithm you wish as long as you can explain it. 4. Call a function that will return the average of the temperatures. The average should be displayed to two decimal places.
Answer:
Following are the program to the given question:
#include<iostream>//defining header file
using namespace std;
float temperatures()//defining a method temperatures
{
int a[10],i,j,n,min,max,sum=0,temp;//defining integer variable
float avg;//defining floating point variable
cout<<"Please input the number of temperatures to be read: ";//print message
cin>>n;//input integer value
if(i>10)//use if to check array length greater than 10
return -1;//return integer value -1
for(j=0;j<n;j++)//defining loop to input value
{
cout<<"Input temperature: "<<endl;//print message
cin>>a[j];//holding value in loop
}
for(i=0;i<n-1;i++)//defining loop to compare array value
{
for(j=i+1;j<n-1;j++)//defining loop to compare array value
{
if(a[i]>a[j])//use if to compare array values
{
//swapping
temp=a[j];//holding array value in temp
a[j]=a[i];//holding value in first index of array
a[i]=temp;//holding temp value
}
}
}
max=min=a[0];//holding max value
for (i = 0; i < n; i++)//defining loop to compare array value
{
if (a[i] > max)//use if to compare max array value
{
max = a[i];//holding max array value
}
else if (a[i] < min)//use else if to compare min array value
{
min = a[i];//holding min array value
}
}
for(i=0;i<n;i++)//use loop to add array value
sum=sum+a[i];//adding array value
avg=(float) sum/n;//calculating avg of the array
std::cout.setf(std::ios::fixed);//using namespace
std::cout.precision(2);//using precision method
cout<<"The average temperature is: "<<avg<<endl;//print avg value with message
cout<<"The highest temperature is: "<<max<<endl;//print max value with message
cout<<"The lowest temperature is: "<<min<<endl;//print min value with message
return avg;//return avg value
}
int main()//defining main method
{
float k;//defining float variable
k=temperatures();//calling method
}
Output:
Please find the attached file.
Explanation:
In this code, a method "temperatures" is declared that defines the integer and float variable in which "n, array" is used to store the array value and inside the method min and max variable is declared that use the conditional statement to store its value.
Outside the main method, a floating-point variable "k" is declared that calls the method and stores its value.

arrowBaseWidth = scnr.nextInt();
while (arrowHeadWidth >= arrowBaseWidth)
{
System.out.println("Enter arrow head width:");
arrowHeadWidth = scnr.nextInt();
}
// Draw arrow base (height = 3, width = 2)
for(int i=0; i < arrowBaseHeight; ++i)
{
for(int j=0; j < arrowBaseWidth; ++j)
{
System.out.print("*");
}
System.out.println();
}
// Draw arrow head (width = 4)
for(int i=0; i < arrowHeadWidth; ++i)
{
for(int j=0; j < arrowHeadWidth-i; ++j)
{
System.out.print("*");
}
System.out.println();
}
return;
}
}
Answer:
The modified program in Java is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int arrowHeadWidth, arrowBaseWidth, arrowBaseHeight;
System.out.print("Head Width: "); arrowHeadWidth = input.nextInt();
System.out.print("Base Width: "); arrowBaseWidth = input.nextInt();
System.out.print("Base Height: "); arrowBaseHeight = input.nextInt();
while (arrowHeadWidth <= arrowBaseWidth) {
System.out.print("Head Width: "); arrowHeadWidth = input.nextInt();
System.out.print("Base Width: "); arrowBaseWidth = input.nextInt(); }
for(int i = 0; i<arrowBaseHeight; i++){
for(int j = 0; j<arrowBaseWidth;j++){
System.out.print("*"); }
System.out.println(); }
for(int i = arrowHeadWidth; i>0;i--){
for(int j = 0; j<i;j++){
System.out.print("*"); }
System.out.println(); }
}
}
Explanation:
This declares the arrow dimensions
int arrowHeadWidth, arrowBaseWidth, arrowBaseHeight;
This get input for the head width
System.out.print("Head Width: "); arrowHeadWidth = input.nextInt();
This get input for the base width
System.out.print("Base Width: "); arrowBaseWidth = input.nextInt();
This get input for the base height
System.out.print("Base Height: "); arrowBaseHeight = input.nextInt();
This loop is repeated until the head width is greater than the base width
while (arrowHeadWidth <= arrowBaseWidth) {
System.out.print("Head Width: "); arrowHeadWidth = input.nextInt();
System.out.print("Base Width: "); arrowBaseWidth = input.nextInt(); }
This iterates through the base height
for(int i = 0; i<arrowBaseHeight; i++){
This iterates through the base width
for(int j = 0; j<arrowBaseWidth;j++){
This fills the base
System.out.print("*"); }
This prints a new line
System.out.println(); }
These iterate through the arrow head
for(int i = arrowHeadWidth; i>0;i--){
for(int j = 0; j<i;j++){
This fills the arrow head
System.out.print("*"); }
This prints a new line
System.out.println(); }

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);
System.out.print("side a = ");
int a = input.nextInt();
System.out.print("side b = ");
int b = input.nextInt();
System.out.print("side c = ");
int c = input.nextInt();
if (a == b && b == c)
{
System.out.println("Equilateral Triangle);
}
else if (a == b || b == c || a == c) {
if ( (int) math.pow(c, 2) == (int) (math.pow(a, 2) + math.pow(b, 2)))
{
System.out.println("Isoscles Right Triangle");
}
else {
System.out.println("Isoscles triangle that is not a right triangle");
}
}
else {
System.out.println("Triangle that is not Isoscles nor Equilateral");
}
}
}

The manager of the Super Supermarket would like to be able to compare the unit price for products sold there. To do this, the program should input the name and price of an item per pound and its weights in pounds and ounces. Then it should determine and display the unit price (the price per ounce) of that item and the total cost of the amount purchased. You will need the following variables:
ItemName PoundPrice Pounds
TotalPrice Ounces UnitPrice
You will need the following formulas:
UnitPrice = PoundPrice/16
TotalPrice = PoundPrice * (Pounds + Ounces/16)
Answer:
ItemName=input("Enter the name of the item purchased: ")
PoundPrice=input("Enter the price of an item per pound: ")
Pound=input("Enter the weight in pound: ")
Ounce=input("Enter the weight in ounce: ")
UnitPrice=int(PoundPrice)/16
TotalPrice=int(PoundPrice)*(int(Pound)+int(Ounce)/16)
print("The unit price is: "+UnitPrice)
print("The total price is: "+TotalPrice)

Katie and her mom had an argument. Katie was at the mall when her mom called on her cell phone. What type of noise came up in their
communication?
Answer:
Noise pollution.
Explanation:
Noise pollution is too loud noise that is harmful to health or that significantly reduces the comfort of the environment or significantly impairs work. Noise pollution arises, for example, from traffic and work machines, as well as from noisy events such as open-air concerts. Noise pollution can also arise from industrial plants (such as wind turbines, rock crushers), work machines (such as cargo handling equipment in ports and other sites), individual machines and equipment (such as leaf blowers, clearing and chainsaws, air conditioners), water pumps) and other noise sources. The noise of the work machines also causes inconvenience to the user of the device if the source of the noise is close to the hearing system of the machine operator.

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);
}
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:

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));
} }

Which operation would occur in the equation =C3+D5*C6-B2 in excel.
Answer:
The operation that will occur first is D5*C6 (multiplication).
Explanation:
Excel’s default order of operator precedence mandates that Excel perform multiplication before addition and substraction. If you want the addition or substraction to be performed before multiplication or division, they must be in parentheses.
The order of operations in exel is:
1. Evaluate items in parentheses.
2. Evaluate ranges (:).
3. Evaluate intersections (spaces).
4. Evaluate unions (,).
5. Perform negation (-).
6. Convert percentages (%).
7. Perform exponentiation (^).

10. Evaluate text operators (&).
11. Perform comparisons (=, <>, <=, >=).
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.

Martha works as a systems administrator in a multinational corporation. One of her colleagues is going on a sabbatical for six months. Martha must ensure that no one uses the colleague's user account until he returns. Which of the following actions can she take to ensure this?
a. Lock out the account
b. Disable the account
c. Change the account's password
d. Delete the account
Answer: Change the account's password
Explanation:
Since Martha wants to ensure that no one uses the colleague's user account until he returns, the best thing for her to do is to change the account's password.
If she changes the accounts password, then she can be the one that will have access to the account and then ensure its safety. It should be noted that the colleague's account can contain vital data and information, therefore it's vital to keep it safe.
