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".

how do i solve this. step by step
The table of values of the kids name and the ages, hat and animal when completed is shown below
Completing the table of valuesBased on the given information, we can make the following deductions:
Only the 10.year old kid has the same initial in his/her name and in his/her beloved animal
So, we have
Gorilla - Gabriel or
Lion - Lucas
Gabriel either has a green hat or loves the gorilla
So, we have
Gabriel -- Green or Gorilla
Lion - Lucas
The crocodile is either Zaira's favorite, or the kid with the white hat's favorite.
This means that
Zaira --- Crocodile or White hat --- Crocodile
Neither Gabriel nor Lucas are 12
Gabriel -- 11 or 13
Gabriel is 1 year older than the kid with the red hat and Neither of them love the zebra
This means that
Red hat --- 12
Gabriel -- Green or Gorilla -- 13
So, we have the following:
Kid's Age Kid's Name Hat Color Favorite Animal
13 Gabriel Green Lion
10 Zaira White Crocodile
12 Lucas Red Lion

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 .

It involves breaking down a larger table into smaller, more focused tables that have a single topic or theme.
Therefore, the goal of normalization is to eliminate data redundancy and improve data integrity by avoiding common issues such as update anomalies, insertion anomalies, and deletion anomalies. By reducing the number of duplicate entries, normalization ensures that data is consistent and easier to maintain.

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.
Programmers sat the statements that are contained in a module have been______
In order to build a coherent and reusable unit of code, programmers "modularize" or "encapsulate" the statements that make up a module.
What in computer terms is a module?A module in computer software is an addition to a main programme that is devoted to carrying out a particular task. A module in computing is a chunk of code that is inserted all at once or is made to be easily reused.
What does programming use sentences for?A group of expressions and/or statements that you create to carry out a task or an activity constitute a statement. Statements are binary; they either carry out duties or do not. Any statement that has the ability to produce a value qualifies by default for use as an expression.

in java code All permutations of names Write a program that lists all ways people can line up for a photo (all permutations of a list of Strings). The program will read a list of one word names (until -1), and use a recursive method to create and output all possible orderings of those names separated by a comma, one ordering per line. When the input is: Julia Lucas Mia -1 then the output is (must match the below ordering): Julia, Lucas, Mia Julia, Mia, Lucas Lucas, Julia, Mia Lucas, Mia, Julia Mia, Julia, Lucas Mia, Lucas, Julia
Answer:
Here's an example Java code that can print all permutations of names given as input:
Explanation:
import java.util.Scanner;
public class Permutations {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String[] names = new String[10];
int n = 0;
// read the names from input and store them in an array
while (input.hasNext()) {
String name = input.next();
if (name.equals("-1")) {
break;
}
names[n++] = name;
}
// call the method to print all permutations of names
printPermutations(names, 0, n-1);
}
// recursive method to print all permutations of names
public static void printPermutations(String[] names, int left, int right) {
if (left == right) {
// base case: if left and right are equal, it means we have reached the end of the name list
for (int i = 0; i <= right; i++) {
if (i == right) {
System.out.print(names[i]); // print the last name without a comma
} else {
System.out.print(names[i] + ", "); // print the name with a comma after it
}
}
System.out.println(); // print a new line after printing the names
} else {
// recursive case: perform permutations of names at different positions
for (int i = left; i <= right; i++) {
// swap the name at position i with the name at position left
String temp = names[left];
names[left] = names[i];
names[i] = temp;
// perform permutations at position left+1
printPermutations(names, left+1, right);
// swap the name at position i back to its original position
names[i] = names[left];
names[left] = temp;
}
}
}
}
explain asymptonic notation?
explain limit rule?
A mathematical notation known as asymptotic notation is used to explain how a function behaves when the input size approaches infinity. Analyzing the effectiveness of algorithms and data structures is a common use for it.
Explain what asymptotic notations are.As the input of an algorithm tends towards a specific value or a limiting value, asymptotic notations are used to mathematically define the program's running duration. For instance: The bubble sort algorithm runs in linear time, which is the best case scenario, when the input array has already been sorted.
Which rule governs limit notation?Limit notation is a more nuanced means of expressing a concept than just saying or. Any number or infinity can serve as the letter.
