write a program that calculates the total grade for N classroom exerices as a perfentage. the user should input the value for N followed by each of the N scores and totals.
Answer:
earned = 0
total = 0
exercises = int(input("Enter the number of exercises: "))
for i in range(exercises):
score = int(input("Enter score" + str(i+1) + ": "))
total_score = int(input("Enter total score for exercise " + str(i+1) + ": "))
earned += score
total += total_score
print("The total is %" + str(earned/total * 100))
Explanation:
*The code is in Python.
Set the earned and total as 0
Ask the user to enter the number of exercises
Create a for loop that iterates number of exercises times. For each exercise;
Ask the user to enter the score earned and total score of that exercise
Add the score to the earned (cumulative sum)
Add the total_score to the total (cumulative sum)
When the loop is done, calculate the percentage, divide earned by the total and multiply the result by 100, and print it
The two statements belowchar dance1[ ] = {'F','o','x','t','r','o','t'};String dance2 = new String(dance1);will generate an error message:
a. because char variables and String variable do not mix.
b. will generate an error message because char variables and String variable do not mix.
c. show that a String variable, like dance2, is an array.
d. demonstrate that a character array can be used to construct a String object.
e. prove that character variables and String variables are identical.
Answer:
D. Demonstrate that a character array can be used to construct a String object.
Explanation:
Option D answers the question.
This is so because:
The first line of the code segment creates a char array element i.e. dance1
The second line of the code segment creates a String variable, dance2.
dance2 is then initialised by concatenating the elements in dance1.
i.e. The value of dance2 is
dance2 = "Foxtrot"
Hence, option D answers the question

Explanation:
In C language, the asterisks, ' * ', and the ampersand, ' & ', are used to create pointers and references to pointers respectively. The asterisks are used with unique identifiers to declare a pointer to a variable location in memory, while the ampersand is always placed before a variable name as an r_value to the pointer declared.

Click Create. A new blank document appears in the Word window.
Explanation:
(1) Prompt the user to enter a string of their choosing. Output the string.
Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself.
(2) Complete the GetNumOfCharacters() function, which returns the number of characters in the user's string. Use a for loop in this function for practice. (2 pts)
(3) In main(), call the GetNumOfCharacters() function and then output the returned result. (1 pt) (4) Implement the OutputWithoutWhitespace() function. OutputWithoutWhitespace() outputs the string's characters except for whitespace (spaces, tabs). Note: A tab is '\t'. Call the OutputWithoutWhitespace() function in main(). (2 pts)
Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself. Number of characters: 46 String with no whitespace: The only thing we have to fear is fear itself.
Answer:
The solution is given in the explanation section
See comments for detailed explanation of each step
Explanation:
import java.util.Scanner;
class Main {
public static void main(String[] args) {
//Prompting the User to enter a String
System.out.println("Enter a sentence or phrase: ");
//Receiving the string entered with the Scanner Object
Scanner in = new Scanner (System.in);
String user_word = in.nextLine();
//OutPuting User entered string
System.out.println("You entered: "+user_word);
//Calling the GetNumOfCharacters Method
System.out.println("Number of characters: "+ GetNumOfCharacters(user_word));
//Calling the OutputWithoutWhitespace Mehtod
System.out.println("String with no whitespace: "+OutputWithoutWhitespace(user_word));
}
//Creating the function GetNumOfCharacters()
//This function will return the number of characters
// in the string entered by the user_word
public static int GetNumOfCharacters (String word) {
int noOfCharacters = 0;
for(int i = 0; i< word.length(); i++){
noOfCharacters++;
}
return noOfCharacters;
}
//Creating the OutputWithoutWhitespace() method
//This method will remove all tabs and spaces from the original string
public static String OutputWithoutWhitespace(String word){
//Use the replaceAll all method of strings to replace all whitespaces with no space.
String new_string = word.replaceAll(" ","");
return new_string;

Create an interface called Runner. The interface has an abstract method called run() that displays a message describing the meaning of run to the class. Create classes called Machine, Athlete, and PoliticalCandidate that all implement Runner.
The run() should print the following in each class:
Machine - When a machine is running, it is operating.
Athlete - An athlete might run in a race, or in a game like soccer.
PoliticalCandidate - A political candidate runs for office.
----------------------------------------------------------------------------------------------------
public class Athlete implements Runner
{
public void run()
{
// write your code here
}
}

public class DemoRunners
{
public static void main(String[] args)
{
Machine runner1 = new Machine();
Athlete runner2 = new Athlete();
PoliticalCandidate runner3 = new PoliticalCandidate();
runner1.run();
runner2.run();
runner3.run();
}

public void run()
{
// write your code here
}
}
----------------------------------------------------------------------------------------------------
public interface Runner
{
// write your code here
}
----------------------------------------------------------------------------------------------------
Answer:
Here is the interface Runner:
public interface Runner { //interface Runner
public abstract void run(); } //abstract method run that displays a message describing the meaning of run to the class
/*Here Runner is the interface which is an abstract class. It is used to group related methods such as here is run method with empty body. An abstract method run() does not have a body. The body is provided by the sub classes Machine, Athlete, and PoliticalCandidate that all implement Runner. */
Explanation:
Here is the Athlete class:
public class Athlete implements Runner { //class that implements Runner interface
public void run() { //interface method accessed by Athlete to provide its body according to describe the meaning of run to the class
System.out.println("An athlete might run in a race, or in a game like soccer."); } } //prints this message
Here is the Machine class:
public class Machine implements Runner {
public void run() {
System.out.println("When a machine is running, it is operating."); }}
Here is the PoliticalCandidate class:
public class PoliticalCandidate implements Runner {
public void run() {
System.out.println("A political candidate runs for office."); } }
/*To access the interface Runner method run(), the Runner must be "implemented" by Machine, Athlete, and PoliticalCandidate classes with the implements keyword. The body of the interface method run() is provided by the "implement" class */
Here is the DemoRunners class:
public class DemoRunners { //class name
public static void main(String[] args) { //start of main method
Machine runner1 = new Machine(); //creates object of Machine class
Athlete runner2 = new Athlete(); //creates object of Athlete class
PoliticalCandidate runner3 = new PoliticalCandidate(); //creates object of PoliticalCandidate class
runner1.run(); //uses object of Machine class to call run method
runner2.run(); //uses object of Athlete class to call run method
runner3.run(); } } //uses object of PoliticalCandidate class to call run method
When runner1.run() is called it invokes the run() method of class Machine which displays the message:
When a machine is running, it is operating.
When runner2.run() is called it invokes the run() method of class Athlete which displays the message:
An athlete might run in a race, or in a game like soccer.
When runner3.run() is called it invokes the run() method of class PoliticalCandidate which displays the message:
A political candidate runs for office.

The government of a country wants to know how much inbound tourism (number of tourists visiting from other countries) is contributing to the country’s economic prosperity. The research firm hired to conduct this study surveys 10,000 residents on their favorite spots to visit in the country and how much money they spend on leisurely activities
a. How could the use of a sample like this threaten the value of the study’s outcomes?
b. How might the flawed sample affect the usefulness of the results?
Answer and Explanation:
A. The study by the research team may not reflect the purpose of the research which is to know how much inbound tourism is contributing to the economy. They are sampling the population on their favorite spots to visit( which may be too narrow here) and what their leisure activities are (which are not the only things tourists spend on). Also 10000 residents may be too small as a sample to reflect more accurate study outcome representative of the population.
2. A flawed sample which is a sampling error would not represent the population as the results from sample would contradict population results

Explanation:
umm that is a todler song that they sing to them when there crying
A country, called Simpleland, has a language with a small vocabulary of just “the”, “on”, “and”, “go”, “round”, “bus”, and “wheels”. As per the given scenario, the vector of counts will be 2111211. The correct option is C.
What are the ways to count items in a vector?C++ has a built-in function that counts the length of the vector. Size is the function's name ().
It returns the size or total number of elements of the vector that was utilized to create it. There is no need for debate.
The number of observations (rows) includes deleted observations as well. In an SAS data collection, there can be a maximum of 2 63-1 observations, or roughly 9.2 quintillion observations. For the majority of users, going above that limit is quite rare.
The vector of counts in the above scenario will be 2111211.
