The incorrect statement about phrase structure grammars is option (C) - In derivations by right linear grammars, only one nonterminal can appear in sentential forms.

Phrase Structure Grammars (PSGs), also known as Context-Free Grammars, are formal systems used to describe the syntax or structure of languages. Let's analyze each statement:

(A) PSG is a 4-tuple that contains nonterminals, alphabets, production rules, and a starting nonterminal.

This statement is correct. A PSG is indeed represented as a 4-tuple, consisting of nonterminals (variables representing syntactic categories), alphabets (terminals representing actual words or tokens), production rules (defining how nonterminals can be rewritten), and a starting nonterminal (the initial symbol from which derivations start).

(B) We apply production rules to rewrite a sentential form into another until we reach a string of terminal symbols.

This statement is correct. In PSGs, production rules are used to rewrite sentential forms by replacing nonterminals with sequences of terminals and/or nonterminals. This process continues until a sentential form is formed entirely of terminal symbols, representing a valid string in the language.

(C) In derivations by right linear grammars, only one nonterminal can appear in sentential forms.

This statement is incorrect. In right linear grammars, also known as right regular grammars, multiple nonterminals can appear in sentential forms. Right linear grammars have production rules where the right-hand side consists of a single terminal or a terminal followed by a nonterminal.

(D) Production rules are a relation from the cartesian product of nonterminals and terminals to the vocabulary of the grammar.

This statement is incorrect. Production rules define the rewriting rules in a PSG. They are a relation from nonterminals to sequences of terminals and/or nonterminals. They specify how to replace a nonterminal with a particular sequence of symbols.

Therefore, the correct answer is option (C) - In derivations by right linear grammars, only one nonterminal can appear in sentential forms.

within the head section insert a script element connecting the page to the clock9-1.js file. Add the defer attribute to the script element to defer the loading of the script until after the page contents load.

insert the runClock() function. Within the function do the following:

Declare the thisDay variable containing the current date using the new Date() command.
Create the thisDate variable containing the text string of the current date by applying the toLocaleDateString() method to the thisDay variable.
Create the thisDayNum variable to store the number of the current weekday by applying the getDay() method to the thisDay variable.
Create the thisWeekday variable by storing the value returned by the getWeekday() function using thisDayNum as the function value.
Create the thisTime variable containing the text string of the current date by applying the toLocaleTimeString() method to the thisDay variable.
Using the textContent property, change the text stored in the document element with the ID date to the value of the thisDate variable, the text stored in the document with element with wday ID to the value of the thisWeekday variable, and the text stored in the document element with the ID time to the value of the thisTime variable.

Directly before the runClock() function insert a statement to run the runClock() function and then another statement that uses the setInterval() method to run the runClock() function every second.

Adjust the code you wrote for the last problem to allow for sponsored Olympic events. Add an amount of prize money for Olympians who won an event as a sponsored athlete.

The

Get_Winnings(m, s)
function should take two parameters — a string for the number of gold medals and an integer for the sponsored dollar amount. It will return either an integer for the money won or a string Invalid, if the amount is invalid. Olympians can win more than one medal per day.

Here's my answer for question 1 please adjust it thanks!

def Get_Winnings(m):

if m == "1": return 75000

elif m == "2":

return 150000

elif m == "3":

return 225000

elif m == "4":

return 300000

elif m == "5":

return 375000

else:

return "Invalid"

In 2008, Francine purchased a cottage in the country for $110,000. During the entire period she has
owned the property, Francine has spent three weeks at the cottage during the summer and
approximately one weekend each month the rest of the year.
Following her marriage a few years ago, Francine, who is 67 years old, felt it was an opportune time to downsize her main home. Accordingly, she sold the house she owned in the city and moved into the apartment rented by her new husband. She claimed her house as her principal residence from 2011 to 2016 (inclusive).
Unfortunately, in 2020, Francine had a marital breakdown and she was forced to sell her cottage receiving proceeds of $595,000.
How much of her capital gain on the cottage can she exempt from taxation?
O a) $0
O b) $242,500
O c) $298,462
d) $485,000

For this exercise, you will complete the TicTacToe Board that we started in the 2D Arrays Lesson.

We will add a couple of methods to the TicTacToe class.

To track whose turn it is, we will use a counter turn. This is already declared as a private instance variable.

Create a getTurn method that returns the value of turn.

Other methods to implement:

printBoard()- This method should print the TicTacToe array onto the console. The board should include numbers that can help the user figure out which row and which column they are viewing at any given time. Sample output for this would be:

0 1 2
0 - - -
1 - - -
2 - - -
pickLocation(int row, int col)- This method returns a boolean value that determines if the spot a user picks to put their piece is valid. A valid space is one where the row and column are within the size of the board, and there are no X or O values currently present.
takeTurn(int row, int col)- This method adds an X or O to the array at position row,col depending on whose turn it is. If it’s an even turn, X should be added to the array, if it’s odd, O should be added. It also adds one to the value of turn.
checkWin()- This method returns a boolean that determines if a user has won the game. This method uses three methods to make that check:

checkCol- This checks if a player has three X or O values in a single column, and returns true if that’s the case.
checkRow - This checks if a player has three X or O values in a single row.
checkDiag - This checks if a player has three X or O values diagonally.
checkWin() only returns true if one of these three checks is true.

public class TicTacToeTester
{
public static void main(String[] args)
{
//This is to help you test your methods. Feel free to add code at the end to check
//to see if your checkWin method works!
TicTacToe game = new TicTacToe();
System.out.println("Initial Game Board:");
game.printBoard();

//Prints the first row of turns taken
for(int row = 0; row < 3; row++)
{
if(game.pickLocation(0, row))
{
game.takeTurn(0, row);
}
}
System.out.println("\nAfter three turns:");
game.printBoard();



}
}

public class TicTacToe
{

private int turn;
private String[][] board = new String[3][3];

public TicTacToe()
{
for(int i = 0; i < 3; i++)
{
for(int j = 0; j < 3; j++)
{
board[i][j] = "-";
}
}
}

//this method returns the current turn
public int getTurn()
{
return turn;
}

/*This method prints out the board array on to the console
*/
public void printBoard()
{

}

//This method returns true if space row, col is a valid space
public boolean pickLocation(int row, int col)
{
return true;
}

//This method places an X or O at location row,col based on the int turn
public void takeTurn(int row, int col)
{

}

//This method returns a boolean that returns true if a row has three X or O's in a row
public boolean checkRow()
{
return true;
}

//This method returns a boolean that returns true if a col has three X or O's
public boolean checkCol()
{
return true;
}

//This method returns a boolean that returns true if either diagonal has three X or O's
public boolean checkDiag()
{
return true;
}

//This method returns a boolean that checks if someone has won the game
public boolean checkWin()
{
return true;
}

}
