Let T be the statement: The sum of any two rational numbers is rational. Then T is true, but the following "proof is incorrect. Find the mistake. "Proof by contradiction: Suppose not. That is, suppose that the sum of any two rational numbers is not rational. This means that no matter what two rational numbers are chosen their sum is not rational. Now both 1 and 3 are 1/1 and 3 3/1, and so both are ratios of integers with rational because 1 a nonzero denominator. Hence, by a supposition, the sum of 1 and 3, which is 4, is not rational. But 4 is rational because 4 4/1 , which is a ratio of integers with a nonzero denominator. Hence 4 is both rational and not rational, which is a contradiction. This contradiction shows that the supposition is false and hence statement T is true.
Answer:
the mistake is in the first statement.
Explanation:
Now lets us put the statement into consideration:
"The sum of any two rational numbers is irrational"
The negation is: " there exists a pair of rational numbers whose sum is irrational". (Existence of at least one of such a pair).
The negation is not "the sum of any two rational numbers is irrational"
Therefore the mistake is in the first statement and it is due to incorrect negation of the proof.

Explanation: Edge 2023
Consider the GBN protocol with a sender window size of 4 and a sequence number range of 1,024. Suppose that at time t, the next in-order packet that the receiver is expecting has a sequence number of k. Assume that the medium does not reorder messages. Answer the following questions: What are the possible sets of sequence numbers inside the sender’s window at time t? Justify your answer. What are all possible values of the ACK field in all possible messages currently propagating back to the sender at time t? Justify your answer.
Answer:
Follows are the solution to this question:
Explanation:
In point a:
N = Size of window = 4
Sequence Number Set = 1,024
Case No. 1:
Presume the receiver is k, and all k-1 packets were known. A window for the sender would be within the range of [k, k+N-1] Numbers in order
Case No. 2:
If the sender's window occurs within the set of sequence numbers [k-N, k-1]. The sender's window would be in the context of the sequence numbers [k-N, k-1]. Consequently, its potential sets of sequence numbers within the transmitter window are in the range [k-N: k] at time t.
In point b:
In the area for an acknowledgment (ACK) would be [k-N, k-1], in which the sender sent less ACK to all k-N packets than the n-N-1 ACK. Therefore, in all communications, both possible values of the ACK field currently vary between k-N-1 and k-1.
What is a special type of variable used in subroutines that refers to a piece of data?
Answer: A parameter or a formal argument is used
Write a function index(elem, seq) that takes as inputs an element elem and a sequence seq and returns the index of the first occurrence of elem in seq. The sequence seq can be either a list or a string. If seq is a string, elem will be a single-character string; if seq is a list, elem can be any value. If elem is not an element of seq, the function should return the length of the sequence. Dont forget that the index of the first element in a sequence is 0. Here are some examples: >>> index(5, [4, 10, 5, 3, 7, 5]) solution
Answer:
def index(elem, seq):
for i in range(len(seq)):
if elem == seq[i]:
return i
return len(seq)
print(index(5, [4, 10, 8, 5, 3, 5]))
Explanation:
Create a function named index that takes elem and seq as parameters
Create a for loop that iterates through the seq. If elem is equal to the item in the seq, return the i, index of the item.
If the elem is not found in the seq, this means nothing will be returned in the loop, just return the length of the seq, len(seq)
Call the function with given parameters and print the result
Note: Since 5 is in the list in the example, the index of the 5 which is 3 will be returned
In this exercise we have to use the knowledge of computational language in Python, so we have that code is:
It can be found in the attached image.
What is an index in Python?An index, in your example, refers to a position within an ordered list. Python strings can be thought of as lists of characters; each character is given an index from zero to the length minus one.
So, to make it easier, the code in Python can be found below:
def index(elem, seq):
for i in range(len(seq)):
if elem == seq[i]:
return i
return len(seq)
print(index(5, [4, 10, 8, 5, 3, 5]))

Write a program that prompts the user to enter: The cost of renting one room The number of rooms booked The number of days the rooms are booked The sales tax (as a percent). The program outputs: The cost of renting one room The discount on each room as a percent The number of rooms booked The number of days the rooms are booked The total cost of the rooms The sales tax The total billing amount. Your program must use appropriate named constants to store special values such as various discounts.
Answer:
Written in Python
cost = float(input("Cost of one room: "))
numrooms = int(input("Number of rooms: "))
days = int(input("Number of days: "))
salestax = float(input("Sales tax (%): "))
print("Cost of one room: "+str(cost))
print("Discount: 0%")
print("Number of rooms: "+str(numrooms))
print("Number of days: "+str(days))
totalcost = numrooms * cost
print("Total cost: "+str(totalcost))
salestax = salestax * totalcost/100
print("Sales tax: "+str(salestax))
print("Total Billing: "+str(salestax + totalcost))
Explanation:
The next four lines prompts user for inputs as stated in the question
cost = float(input("Cost of one room: "))
numrooms = int(input("Number of rooms: "))
days = int(input("Number of days: "))
salestax = float(input("Sales tax (%): "))
The following line prints cost of a room
print("Cost of one room: "+str(cost))
The following line prints the discount on each room (No information about discount; So, we assume it is 0%)
print("Discount: 0%")
The following line prints number of rooms
print("Number of rooms: "+str(numrooms))
The following line prints number of days
print("Number of days: "+str(days))
The following line calculates total cost of rooms
totalcost = numrooms * cost
The following line prints total cost
print("Total cost: "+str(totalcost))
The following line calculates sales tax
salestax = salestax * totalcost/100
The following line prints sales tax
print("Sales tax: "+str(salestax))
The following line calculates and prints total billings
print("Total Billing: "+str(salestax + totalcost))

Write a Java program that generates a random number between 0 and 50. Then, the program prompts for guesses until the user is correct, or has made 10 wrong guesses. After each guess, the program indicates whether the guess was too high, too low, or correct. Once the round has ended, either by a correct guess or by using up the 10 guesses, the program displays the current status. Enter an integer number ( 0 to exit): 3241 3241 has 4 digits. Sum of digits of 3241 is 10. Enter an integer number ( 0 to exit): 264 264 has 3 digits. Sum of digits of 264 is 12. Enter an integer number ( 0 to exit): -12 -12 has 2 digits. Sum of digits of -12 is -3. Enter an integer number ( 0 to exit): 0 End. Enter a positive integer between 0 and 9: -3 Invalid input number. Enter a positive integer between 0 and 9: 15 Invalid input number. Enter a positive integer between 0 and 9: 5 0 !
Answer:
Here is the JAVA program:
import java.util.Scanner; //to accept input from user
public class Main { //class name
public static void GuessTheNumber() { //method to guess the number
Scanner input = new Scanner(System.in); //creates Scanner object to accept input from user
int number = (int)(50 * Math.random()) ; //generates random number from 0 to 50
int trials = 10; //allows 10 trials to user to guess the number
int i, userGuess; //stores user guess
System.out.println("Guess a number between 0 to 50"); //prompts user to guess a number between 0 to 50
for (i = 0; i <trials; i++) { //allows user to keep guessing in 10 trials
System.out.println("Enter your guess: "); //prompts user to enter a number as a guess
userGuess = input.nextInt(); //reads users entered number(guess)
if (number == userGuess) { //if users guess is correct
System.out.println("Congratulations! The guess is correct!"); //displays congratulatory message
break; } //the loop breaks after correct guess is made
else if (number>userGuess) { //if user guess is less than correct number
System.out.println("Too low"); }
else if (number<userGuess) { //if user guess is greater than correct number
System.out.println("Too high"); } }
if (i == trials) { //if user has made 10 wrong guesses
System.out.println("You exceeded 10 trials!");
System.out.println("The correct number was " + number); } } //displays the correct number if user made 10 wrong guesses
public static void main(String arg[]) { //start of main method
GuessTheNumber(); } } //calls method to start the guessing game
Explanation:
The program prompts the user to enter a guess and it uses random() method to generate randoms numbers from 0 to 50. The loop keeps iterating and prompting the user to enter a guess until the limit of number of trials exceeds. The trials are set to 10 so the user can guess a number in 10 tries. If the user guesses a number that is higher than the correct guess then the program indicates that the guess is too high by displaying a message "too high" and if user guesses a number that is lower than the correct guess then the program indicates that the guess is too low by displaying a message "too low". If user makes 10 wrong guess then the program displays the correct guess and ends. The screenshot of the output is attached.

Answer:
how does the daily path of the sun across the sky change with the seasons?
The path is curved due to Earth's tilted axis. During the days with longer periods of daylight, more light and heat from the Sun strike that hemisphere. So, when the Sun is higher in the sky, its energy is more concentrated on Earth's surface.
