Concept explainers
The Upper West View Yacht club sponsors sailboat races every weekend for its fleet of SuperGee sailboats, and wants to determine which boat is the winner out of every four races. The scoring system is simple: a boat finishing in first position (first place) receives 1 point; a boat in second place receives 2 points, and so on. At the end of four races, the boats are ranked in ascending order by number of points, so the boats with the lowest points win.
Your task is to write an application that lets the user input the finishing position for each of three boats for four races. The program will then display the total points for each boat. Here are some specific requirements:
- Validate all text boxes to make sure the user enters integer values.
- Use a StatusStrip with a label to display an error message. When the user corrects an error and clicks the Calculate button again, clear any existing error message.
- Set TabIndex properties so that the focus will move between input fields in a logical manner.
- Do not allow the user to maximize or resize the form.
Figure 3-62 shows a sample of the program as the user is entering all valid values. In any single race, no place value should appear twice, although you currently do not have the

This corresponds to the Select a Solving Method dropdown list in the Solver Parameters dialog box EngineDesc – optional -this is an alternate way of selecting the solving method – here you would type the strings “Simplex LP”, “GRG Nonlinear” or “Evolutionary”. This also corresponds to the Select a Solving Method dropdown list in the Solver Parameters dialog box What happens when the code demonstrates: Engine:=1, EngineDesc:="GRG Nonlinear" ?arrow_forwardYour soccer team is holding a silent auction dinner as a fundraiser to pay for the team uniforms. The list shows all the expenses for the silent auction. A tablet that costs $280 Soccer tickets that cost $100 A gift card that costs $20 The cost of the food is $400 The members of the soccer team will be selling tickets to the silent auction. A ticket to the silent auction includes chances to win prizes and dinner. The ticket cost is set so that 50 tickets will pay for the cost of the prizes and food. Build a function that can be used to find the total profit, f(x)f(x), the soccer team earns by selling xx tickets. Show your work to build this function. and Your soccer team needs to raise at least $500 more than the total cost of the expenses. What is the minimum number of tickets that must be sold in order for your team to reach their goal? Use mathematics to justify your answer.arrow_forwardInstallation of a Shopee Billboard Max. score: 100 You are installing a billboard and want it to be at the maximum height. The billboard will have two steel supports, one on each side. The height of each steel bracket must be equal. You have a number of rebar rods that can be welded together. For example, if the bars are of length 1, 2, and 3, they can be welded together to form a length of 6 brackets. Return the maximum possible installation height of the billboard. Return 0 if the billboard cannot be installed.arrow_forward

You have chosen the direction you'd like to travel and made a list of cities in that direction that have gas stations to stop at and fill up your tank. To make sure that this route is viable, you need to know the distances between the adjacent cities in order to be able to travel this distance on a single tank of gasoline, (No one likes running out of gas.) but you only know distances to each city from your starting point. Input: Your program should read lines from standard input. Each line contains the list of cities and distances to them, comma delimited, from the starting point of your trip. You start your trip at point 0. The cities with their distances are separated by semicolon. Output: Print out the distance from the starting point to the nearest city, and the distances between two nearest cities separated by comma, in order they appear on the route. Test 1…arrow_forward
