a) The buffer is needed to ensure smooth playback of streamed media by storing a certain amount of data in advance. This is done to prevent interruptions due to network congestion or variations in the streaming rate.
How to calculate the datab) i) The amount of data streamed in 2 seconds is (1.5Mbps * 2s) = 3MB. The amount of data played back in 2 seconds is (600kbps * 2s) = 150KB. Therefore, the amount of data stored in the buffer after 2 seconds is (3MB - 150KB - 200KiB) = 2.6MB.
ii) To determine how long it will take before the buffer reaches its higher limit of 1.8MiB, we can use the following formula:
Time to reach limit = (higher limit - lower limit - current buffer size) / streaming rate
= (1.8MiB - 200KiB - 2MiB) / 1.5Mbps
= 8 seconds
Therefore, it will take 8 seconds for the buffer to reach its higher limit.
c) To overcome the problem of frequent pausing of playback, a larger buffer can be used. This will allow more data to be stored in advance, reducing the impact of network congestion or variations in the streaming rate.'
Additionally, adaptive bitrate streaming can be used, where the streaming rate is dynamically adjusted based on the available network bandwidth, to ensure a more consistent streaming experience. Finally, a content delivery network (CDN) can be used to deliver the media from servers located closer to the viewer, reducing the impact of network latency and improving overall streaming performance.

The shop has been open for a week now and you need to work on the first payroll for your two employees, Sean and Justine. Sean’s hourly pay is $8.25. He worked 10 hours this week and is taxed at a 5% rate. Justine’s hourly pay is $9.00. She worked 30 hours this week and is taxed at a 6% rate.
a) Create a spreadsheet for your payroll. Make sure you use a formula to automatically calculate Total Pay.
Here's a sample spreadsheet for your payroll:
The SpreadsheetEmployee Name Hourly Rate Hours Worked Total Pay Tax Rate Taxes Withheld Net Pay
Sean $8.25 10 =B2*C2 5% =D2*E2 =D2-F2
Justine $9.00 30 =B3*C3 6% =D3*E3 =D3-F3
In this spreadsheet, we have columns for the employee name, hourly rate, hours worked, total pay, tax rate, taxes withheld, and net pay.
For each employee, we use a formula to calculate their total pay based on their hourly rate and hours worked. The formula used in the Total Pay column is "=hourly rate * hours worked".
We also have a column for tax rate, where we input the percentage at which the employee is taxed. Using this tax rate, we calculate the taxes withheld from the employee's pay in the Taxes Withheld column. The formula used in the Taxes Withheld column is "=total pay * (tax rate/100)".
Finally, we calculate the net pay for each employee by subtracting the taxes withheld from their total pay in the Net Pay column. The formula used in the Net Pay column is "=total pay - taxes withheld".

Explain the Hough transform for edge linking with suitable example
Answer:
The Hough transform is a feature extraction technique used in image analysis, computer vision, and digital image processing. It is used to detect simple shapes such as lines, circles, and ellipses in images. The Hough transform algorithm works by mapping points in an image space to lines in a parameter space. The algorithm then searches for peaks in the parameter space to detect lines in the image space.
Edge linking is often applied as a second step after applying the Hough transform. In edge linking, each peak represents a line across the image. You can visit the pixels along that line, find the ones that are set (assuming a binary input image) .
For example, let’s say you have an image of a circuit board with lines on it. You can use edge detection algorithms to detect edges of the lines in the image. Then you can apply the Hough transform algorithm to detect straight lines in the image. Finally, you can apply edge linking to connect these straight lines into longer lines .

Program 2: CustomCanvases.py
A company sells custom rectangular canvases. They will create the canvases for you. You only need to tell them the dimensions of the canvases. They charge $4.99 per square foot and require a minimum order of 20 square feet. You will write a program that asks the user to enter the number of canvases, and the dimensions of each canvas.
Program 2 Requirements:
The program must prompt the user for the number of canvases and set the price per square foot to 4.99.
The program will use a counting loop to loop for the number of canvases.
The loop body will:
Prompt the user for the length and width of each canvas
Multiply the length and width to get the canvas size in square feet.
Accumulate total square footage for all the canvases
Once the loop is complete, ensure that at least 20 square feet are being purchased otherwise display an error.
Final price for valid orders will be calculated by multiplying the total square footage by the price per square foot.
Display the price per square foot, total square footage, and final price.
Displayed values that represent dollar amounts must be formatted as currency, including a dollar sign and 2
decimal places
Below is the code for Program 2:
python
# Program to calculate the price of custom canvases
# Constants
PRICE_PER_SQ_FT = 4.99
MIN_ORDER = 20
# Prompt the user for the number of canvases
num_canvases = int(input("Enter the number of canvases: "))
# Initialize variables
total_sq_ft = 0
final_price = 0
# Loop through the canvases
for i in range(num_canvases):
# Prompt the user for the dimensions of the canvas
length = float(input("Enter the length of canvas {}: ".format(i+1)))
width = float(input("Enter the width of canvas {}: ".format(i+1)))
# Calculate the square footage and accumulate the total
sq_ft = length * width
total_sq_ft += sq_ft
# Check if the minimum order is met
if total_sq_ft < MIN_ORDER:
print("Error: Minimum order not met")
else:
# Calculate the final price
final_price = total_sq_ft * PRICE_PER_SQ_FT
# Display the results
print("Price per square foot: ${:.2f}".format(PRICE_PER_SQ_FT))
print("Total square footage: {:.2f} sq. ft.".format(total_sq_ft))
print("Final price: ${:.2f}".format(final_price))
What is the Program about?Here's an example output for this program:
yaml
Enter the number of canvases: 3
Enter the length of canvas 1: 5
Enter the width of canvas 1: 4
Enter the length of canvas 2: 3
Enter the width of canvas 2: 3
Enter the length of canvas 3: 6
Enter the width of canvas 3: 2
Price per square foot: $4.99
Total square footage: 43.00 sq. ft.
Final price: $214.57
If the user entered canvases with a total square footage less than 20, they would receive the following error message:
yaml
Enter the number of canvases: 2
Enter the length of canvas 1: 2
Enter the width of canvas 1: 3
Enter the length of canvas 2: 2
Enter the width of canvas 2: 2

The program initializes a variable i to 2, which is the first prime number.
The program uses a while loop to loop through all the numbers from 2 to n.
For each number i, the program uses a nested while loop to check if it is prime. The nested while loop checks if i is divisible by any number from 2 to i-1. If it is divisible by any of these numbers, is_prime is set to False, and the nested while loop breaks.
If is_prime is still True after the nested while loop, i is a prime number and the program prints it using the print() function.
The program increments i and resets is_prime to True before looping back to step 4.
Once all the numbers from 2 to n have been checked, the program terminates.

7. Complete the following problem below in java
The program will first display a menu that enables the users to choose whether they
want to view all students 'records or view only the records of a specific student by the
student's id. See sample below.
MENU
1, View all students' records
2. View a student's records by ID
Please enter your choice 1
If the user types in for Choice 1, it displays this:
StudentID | Quiz1 | Quiz2 | Mid-Term | Final |
1232

If the user types in for Choice 2, it will ask the user to enter in an ID. If the user enters in
an invalid ID, the user has to keep entering one in until a correct one is entered. Once a
valid ID is entered, will display the students ID, Quiz1, Quiz2, Mid-Term, and Final
grade.

Explanation:
This program first initializes a 2D array called records with the student records data. It then displays a menu with two choices: 1) view all student records, or 2) view a specific student's record by ID.
The program uses a do-while loop to keep displaying the menu and accepting input until the user chooses either option 1 or option 2. Inside the switch statement, the program either loops through the entire records array to print all student records or prompts the user to enter a student ID and searches the records array for a matching ID to print the corresponding record.
The printf method is used to format the output into columns with fixed widths. If an invalid choice or ID is entered, an error message is displayed and the menu is displayed again. Once the user chooses either option 1 or option 2, the program exits.

Based on the provided pseudocode, if the age equals 10, the output for the ticketPrice would be: 9 (Option A)
What is the explanation for the above response?The provided pseudocode checks the age of a person to determine the ticket price for an event. If the age is less than or equal to 12 or greater than or equal to 60, the ticket price is set to 9.
However, if the age is not within that range, the ticket price is set to 17. In this case, since the age is 10 which satisfies the first condition, the ticket price is set to 9. Therefore, the output is ticketPrice <- 9.

Question 22 of 25
What should the timing of transition slides be per minute
Maintain the flow of the presentation to -*BLANK*- slides per minute.
Answer:
The Answer would be 1 Slide/15 secs
Explanation:
A presentation slide is supposed to be on for 15 seconds and stop to ask if anyone has any questions, if you are explaining something or reading alond with the slide it could be as long as you want it to be.
A 3-character string, passCode, is read from input. Replace the second and third characters in passCode with '$' only if both are digit characters. Otherwise, passCode is not changed.
Ex: If the input is 435, then the output is:
4$$
Ex: If the input is 68p, then the output is:
68p
in c++
Here's the C++ code that implements the given functionality:
#include <iostream>
#include <string>
using namespace std;
int main() {
string passCode;
cin >> passCode;
if (passCode.length() >= 3 && isdigit(passCode[1]) && isdigit(passCode[2])) {
passCode[1] = '$';
passCode[2] = '$';
}
cout << passCode << endl;
return 0;
}
How to explain the programThe program reads a string input passCode from the user and checks if it has at least 3 characters and if the second and third characters are digits. If both conditions are met, it replaces the second and third characters with the '$' character. Finally, it prints the updated passCode string to the console.
Note that the isdigit function from the <cctype> library is used to check if a character is a digit. The string class from the <string> library is used to represent the passCode string.
