Create an application that predicts the approximate size of a population of organisms. The application should use textboxes to allow the user to enter the starting number of organisms, the average daily population increase (as a percentage), and the number of days the organisms will be left to multiply.

Java Programming Joyce Farrell 9th edition Chapter 15-8 Write a JavaFX application that allows the user to choose insurance options. Use a ToggleGroup to allow the user to select only one of two insurance types—HMO (health maintenance organization) or PPO (preferred provider organization). Use CheckBoxes for dental insurance and vision insurance options; the user can select one option, both options, or neither option. As the user selects each option, display its name and price in a TextField; the HMO costs $200 per month, the PPO costs $600 per month, the dental coverage adds $75 per month, and the vision care adds $20 per month.
Create an application that calculates a car’s gas mileage. The formula for calculating the miles that a car can travel per gallon of gas is: MPG=milesgallonsIn the formula MPG is miles-per-gallon, miles is the number of miles that can be driven on a full tank of gas, and gallons is the number of gallons that the tank holds. The application’s form should have TextBox controls that let the user enter the number of gallons of gas the tank holds and the number of miles the car can be driven on a full tank. When the Calculate MPG button is clicked, the application should display the number of miles that the car can be driven per gallon of gas. The form should also have a Clear button that clears the input and results, and an Exit button that ends the application. If the user fails to enter numeric values, display an appropriate error message and do not attempt to perform calculations.
Given the formulas in Figure 11, write a program with the following functions to perform the calculations of area of trapezium and volume of cone. The program should include relevant validation processes. Area of Trapezium = ; xh x (a + b) %3D Volume of cone = Figure 11 main() This function will display a simple menu to repeatedly prompt user for calculation options. If the user chosen the option to calculate the area of a trapezium, the program will call the areaofTrapezium() to perform the calculation process. If the user chosen the option to calculate the volume of a cone, then the program will call the volumeOfCone() to perform the calculation. The main() should display the answer of the calculation return from the functions. Sample menu: [A] Area of Trapezium [B] Volume of Cone [Q] Quit Enter your option: areaoffrapezium()
This code needs to be written in C#: If the user guesses the number in 3rd try you will assign:Points = (10 – 3)^2/100 = 7 ^ 2 = 49 points.When the user presses the ‘Start Game’ button, the game will start. User will enter a number in the largetextbox and press Submit. If number is correct display the Messagebox, else continue with game. Also tellthe user if the number entered was higher or lower than actual number.The problem flow will be as follows:1. Player enters name and number of chances2. Player presses Start game3. Computer generates a secret random number4. Player enters choice5. Program checks if number matches guesses number. If number matches jump to step #106. Program updates message whether the guessed number is more or less than actual7. Program reduces available chances by 1 and display messages on changes8. If chances become 0 stop game and tell use Game has ended, and she will have to press ‘Start Game’again. Same message should be spoken by the program using text to…
Design and implement an application that presents three buttons and a label to the user. The buttons should be labeled Increment, Decrement, and Randomize. Display a numeric value (initially 50) using the label. Each time the Increment button is pushed, increment the value displayed. Likewise, each time the Decrement button is pushed, decrement the value displayed. When the Randomize button is pushed, the number displayed should be randomized between 1 and 100, inclusive.
A Costume shop requests a Computer application that advertizes Costume rentals. This week's Costume rental specials are as follows : Table Costume Price per week Renaissance Fair $40 Stormtrooper $49 Batman / Batgirl $36 Pirate $29 Write an application that allows the user to select any of the five costume rental specials. When the user selects a costume, the corresponding cost and a picture of the costume should be displayed. Clear each prior price and picture when the user selects a different costume.

design pattern question :- Using the state pattern, you have to implement an application that help track the item ordered from online shop. The client orders an item from online shop, then item can go to post office, then it will be delivered to the user home. Or the item after being ordered it goes to the post office, then the user will pick it up from the post office. In both cases; either take the item from the post office or has it delivered to the client's home represents the end of the process. Q1)Draw the state diagram that shows all possible states and transitions? Q2) Write code of the Ordered state? Q3) Write the implementation of the ShopOrder class; most important things are the states declaration, the constructor, a function to return robot state

There are three seating categories at a high school athletic stadium. For a baseball game, Class A seats cost $15 each, Class B seats cost $12 each, and Class C seats cost $9 each. Create an application that allows the user to enter the number of tickets sold for each class. The application should be able to display the amount of income generated from each class of ticket sales and the total revenue generated. If the user fails to enter numeric values, display an appropriate error message and do not attempt to perform calculations Use the following test data to determine if the application is calculating properly:Ticket Sales RevenueClass A: 320 Class A: $4800.00Class B: 570 Class B: $6840.00Class C: 890 Class C: $8010.00Total Revenue: $19650.00Class A: 500 Class A: $7500.00Class B: 750 Class B: $9000.00Class C: 1200 Class C: $10800.00Total Revenue: $27300.00Class A: 100 Class A: $1500.00Class B: 300 Class B: $3600.00Class C: 500 Class C: $4500.00Total Revenue: $9600.00
