This exercise allows a user to enter the values of two, 3x3 matrices and then select from options including, addition, subtraction, matrix multiplication, and element by element multiplication. You should use numpy.matmul() for matrix multiplication (e.g. np.matmul(a, b) ). The program should computer the appropriate results and return the results, the transpose of the results, the mean of the rows for the results, and the mean of the columns for the results. When entering data you should check that each value is numeric for the matrices. The user interface should continue to run until the user indicates they are ready to exit.

If an inappropriate entry is detected, the program should prompt for a correct value and continue to do so until a correct value is entered. Hints: 1. Use numpy and associated functionality 2. Create and use functions as often as possible 3. Use comments to document your code 4. Both integers and float values are acceptable

Write a program named CheckMonth2 that prompts a user to enter a birth month and day.

Display an error message that says Invalid date if the month is invalid (not 1 through 12) or the day is invalid for the month (for example, not between 1 and 31 for January or between 1 and 29 for February).

If the month and day are valid, display them with a message. For example, if the month entered is 2, and the day entered is 17, the output should be 2/17 is a valid birthday.

This is the code i start with. (Answer is C# Please.)

using System;
using static System.Console;
class CheckMonth2
{
static void Main()
{
// Write your main here
}
}

Write functions:

i) One that prompts a user for 2 numbers.

ii) Adds the two numbers if they are even

iii) Multiplies the two numbers if they are odd

iv) Displays the appropriate output to the user

You are writing 4 functions and calling them to test functionality.

6)Describe referential integrity problem in general. In the specific case of deleting a record in a table on the “one side” of a one-to-many relationship, how would referential integrity occur?

Which of the following statements is false?

. Create a Python function that asks the user for a number (integer). The function should then tell the user how many hundreds can go into the number, and how much is left over.

Hint: the % operator calculates the remainder of a division. For example, 10 % 3 gives a result 1.

Hint2: Deal with the positive and negative values in separate parts of an if-else structure. Get the calculation work for positive values first. For negative values, make them positive (num = -num) and then use the same method as for positive values, adapting as

this is a python program so i need your help to complete this task. as i have to submit it by tomorrow.

thanks

Exercise #1:

Create an abstract class called GameTester. The GameTester class includes a name for the game tester and a boolean value representing the status (full-time, part-time).

Include an abstract method to determine the salary, with full-time game testers getting a base salary of $3000 and part-time game testers getting $20 per hour.

Create two subclasses called FullTimeGameTester, PartTimeGameTester. Create a console application that demonstrates how to create objects of both subclasses. Allow the user to choose game tester type and enter the number of hours for the part-time testers.

Exercise #2:

CityToronto bank provides mortgages for individuals and businesses up to $300,000. Write a Java application that keeps track of mortgages and computes the total amount owed at any time (mortgage amount + interest).

Design the following classes to implement your application:

Mortgage – an abstract class that implements the MortgageConstants interface. A Mortgage includes a mortgage number, customer name, amount of mortgage, interest rate, and term.

Don’t allow mortgage amounts over $300,000. Force any mortgage term that is not defined in the MortgageConstants interface to a short-term, one year loan. Create a getMortgageInfo method to display all the mortgage data.

MortgageConstants – includes constant values for short-term (one year), medium-term (three years) and long-term (5 years) mortgages. It also contains constants for bank name and the maximum mortgage amount.

BusinessMortgage – extends Mortgage. Its constructor sets the interest rate to 1% over the current prime rate.

PersonalMortgage - extends Mortgage. Its constructor sets the interest rate to 2% over the current prime rate.

ProcessMortgage – a main class that create an array of 3 mortgages. Prompt the user for the current interest rate. Then in a loop prompts the user for a mortgage type and all relevant information for that mortgage. Store the created Mortgage objects in the array. When data entry is complete, display all mortgages.

Draw a single graph in Python showing the performance of both a linear and binary search algorithm against the number of elements (100,000). Consider the worst case scenario. In the graph we want to see: labeling of the axes, a legend, a title and the graphs for both linear and binary search, again correctly labeled. Explain what you see. Hint: Use Plot Functions (Plot Chart, series from functions) from the H!de Editor.

Program 2 People eating at a restaurant get to eat for free if they are younger than 10, pay full price if they are under 65, get a $3 discount if they are 65 or over. Write a program asking the user for an age of the next customer and the price of the food they ordered. Calculate how much to charge based on the price (set to 0, full price, or with a discount) along with a 15% tip. Then have the program show this amount to the user. Examples: What age is the person 5 What price is the meal 10 The charge for this person is 0 (a second program run) What age is the person 70 What price is the meal 10 The charge for this person is 8.05

(1) T(n)=9⋅T(n3)+n2⋅(log⁡(n))2

(2) T(n) = 10 * T(n/3) + n^2

One of these can be solved using the Master Theorem; the other cannot.

1. Which one can be solved using the Master Theorem? Compute the solution to this recurrence relation.
2. Which one cannot be solved using the Master Theorem? Carefully explain why not.
   (NOTE: A complete solution will use the definition of big-O.)
3. Use another method to solve this recurrence relation. To make this a bit easier, you may assume that n = 3^k for some integer k (so that k = log₃(n)).
   {NOTE: If you use a recursion tree, you clearly cannot sketch it here. You can (and should) indicate the number of nodes -- for recursive calls -- at each level, the time complexity of each node, and the total time complexity for each level.)

1. A pizza restaurant requires 200 grams of flour, 10 ml of olive oil, 100 ml of tomato sauce and 200 grams of cheese to make one of their basic pizzas. The restaurant’s supplier sells bags of flour weighing 5 kg each, drums of olive oil containing 5 litres, cans of tomato sauce containing 2 litres and bags of grated cheese weighing 1 kg. Write a python program to ask the user how many pizzas they expect to make in the following week and work out what supplies would need to bought from the supplier in order to meed the predicted demand. The program should also let the user know what quantities of each ingredient will be left over at the end of the week. include comments

Thanks in advance.
In Java.
I'm having an issue with one of my methods.
Ex:

The array being pass in is a character array with element: w, ' ', K, Q, k, q, ' ', -, ' ', 0, ' ', 1

public class Find
{
public void enPassant(char[] array)
{
  for(int i = 0; i < array.length; ++i)
{
if(array[i] == 'e')
{
count = i;
}
else
{
count += 0;
}
}
  
if(count > 0)
{
System.out.println("En passant: " + array[count] + array[count + 1]);
}
  
if(count == 0)
{
System.out.println("En passant: none");
}
}

public class Main
{
public static void main(String[] args)
{
Find testDetail = new Find();
testDetail.enPassant(detailArray);

}

}

Output: Enpassant: kq

My intended output is: Enpassant: none

Why am i getting kq, and what can i do to correct my mistake?

In C++ Design and implement a program (name it ProcessGrades) that reads from the user four integer values between 0 and 100, representing grades. The program then, on separate lines, prints out the entered grades followed by the highest grade, lowest grade, and averages of all four grades. Format the outputs following the sample runs below.

Use menu based functionality and validation loops to create a new customer bonus fruit package application for the Dirt to Dish discount produce company.

The program you create will prompt the user to enter a number to select one of three bonus pack options:

1 for Apple pack
2 for Orange pack
3 for Banana pack

**Use input validation to ensure a valid option has been selected before proceeding.

Use variables to keep track of how many of each fruit a customer will have depending on which bonus pack has been chosen. The amount of fruit per bonus pack is given as follows:

Banana pack: 5 bananas, 2 apples, 2 oranges
Orange pack: 5 oranges, 2 apples, 2 bananas
Apple pack: 5 apples, 2 bananas, 2 oranges

Use menu based functionality and input validation and prompt the user to choose from one of the following recipes:

1. Fruit medley (2 of each fruit)
2. Mixed Apple Pie (3 apples, 1 orange, 1 banana)
3. Banana tower (4 bananas, 2 oranges)
The amount of fruit required for each recipe is shown in parenthesis.

After a valid recipe choice has been made, subtract the amount of fruit needed for the recipe if the customer has enough fruit. If the customer does not have enough fruit then show a message telling the customer to buy more fruits.

Finally display the amount of fruit remaining from the bonus pack after the recipe selection has been made.

First example run:

This is Dirt to Dish's new customer bonus service!
Please select your free fruit package:
1. Apple pack
2. Orange pack
3. Banana pack
Please enter 1, 2, or 3: 2
You have chosen: Orange pack

You have a total of:
2 apples 5 oranges 2 bananas
Which dish would you like to make first?
1. Fruit medley (2 of each fruit)
2. Mixed Apple Pie (3apples, 1 orange, 1 banana
3. Banana tower (4 bananas, 2 oranges
Please enter 1, 2, or 3: 2
Mixed Apple Pie chosen
Sorry, you need more fruits!
The fruit you have left is:
2 apples
5 oranges
2 bananas

Thank you!

Create a 32-bit Linux-based assembler language program (nasm) which:

1. Defines these variables:

A: A single byte

B: A word

C: A double word

D: A double word

2. Using the eax register (and its sub-registers), process the following equations (ONLY using the mov, add and sub assembly keywords):

I. A + (B + C) = D

II. (A + C) - B = D

3. Using the linux function library, print a string describing each equation, then values in each variable, and then the answer in the resulting variable

4.Use the following values in your equation:

I. 10h

II. 2000h

III. 30000

Sample Output: The Result of A + (B + C) = D is: 32010

When printing out a string in NASM, use the linux function library call PrintString. Make sure your string is 00h terminated. • When printing out a Hexadecimal value in NASM, use the linux function library call Print32bitNumHex
