VBA - EXCEL Engine – optional – this indicates the solving method that needs to be used to get to a solution. 1 for the Simplex LP method, 2 for the GRG Nonlinear method, or 3 for the Evolutionary method. 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" ?

Pendant Publishing edits multi-volume manuscripts for many authors. For each volume, they want a label that contains the author’s name, the title of the work, and a volume number in the form Volume 9 of 9. For example, a set of three volumes requires three labels: Volume 1 of 3, Volume 2 of 3, and Volume 3 of 3. Design an application that reads records that contain an author’s name, the title of the work, and the number of volumes. The application must read the records until eof is encountered and produce enough labels for each work. The flowchart must include a call symbol, at the beginning, to redirect the input to the external data file. create a solution algorithm using pseudocode create a flowchart using RAPTOR

Computer Science Javascript populateSelectMenu function The function populateSelectMenu should exist. The function populateSelectMenu should return undefined if it does not receive users data. The function populateSelectMenu selects and returns the select menu. The function populateSelectMenu receives the option elements from createSelectOptions and appends them to the select element.

Additional Notes: USING C# You cannot add two flights with the same flight number When you select “View Flights”, a list containing the Flight number, origin and destination for each flight must be shown. When you select “View a particular flight”, a list of all flights should be displayed and the user must be allowed to enter a particular flight number. All the information on that selected flight must be displayed. All the customers who are booked on that flight must SPECIAL NOTE: A customer can only be deleted if there are no bookings for that customer. A flight can only be deleted if there are no customers booked on the flight. You must extend the core design and add the functionality to add customers and booking features to the system. The information that must be recorded on a customer is as follows: A customer ID must be assigned to each customer by the system. (NOT entered by the user) The customer’s first name The customer’s last name. The customer’s phone (a string type…
You are working for a company that developed a new drug which increases HDL cholesterol (the good cholesterol). A variety of dosages were given to participants during a trial, and the increases of HDL cholesterol were measured. This information is summarized in the following plot: Dosage vs Increase 80 70 60 50 40 30 20 10 15 x - dosage in mg 10 20 25 30 Each point (x, y) in the above plot represents a participant who was given a dosage of æ mg and had an HDL increase of y mg/dL. This information is stored in the 2d numpy array trial_data. The r-values are stored in the first row of trial_data (i.e. trial_data[@]) and the y-values are stored in the second row of trial_data (i.e. trial_data[1]). You are now working with a physician to determine the right dosage for one of her patients. 1) In order to help your client, first find a vector B = [B1] such that y(x) = B1 + Bza is the least squares line [B2] for the above data. Store the vector B as a 1D-numpy array in beta. 2) The physician…
In this exercise, you modify the Grade Calculator application from this chapter’s Apply lesson. Use Windows to make a copy of the Grade Solution folder. Rename the copy Grade Solution-Intermediate. Open the Grade Solution.sln file contained in the Grade Solution-Intermediate folder. Open the CourseGrade.vb file. The DetermineGrade method should accept an integer that represents the total number of points that can be earned in the course. (Currently, the total number of points is 200: 100 points per test.) For an A grade, the student must earn at least 90% of the total points. For a B, C, and D grade, the student must earn at least 80%, 70%, and 60%, respectively. If the student earns less than 60% of the total points, the grade is F. Make the appropriate modifications to the DetermineGrade method and then save the solution. Unlock the controls on the form. Add a label control and a text box to the form. Change the label control’s Text property to “&Maximum points:” (without the quotation marks). Change the text box’s name to txtMax. Lock the controls and then reset the tab order. Open the form’s Code Editor window. The txtMax control should accept only numbers and the Backspace key. Code the appropriate procedure. The grade should be cleared when the user makes a change to the contents of the txtMax control. Code the appropriate procedure. Modify the frmMain_Load procedure so that each list box displays numbers from 0 through 200. Locate the btnDisplay_Click procedure. If the txtMax control does not contain a value, display an appropriate message. The maximum number allowed in the txtMax control should be 400; if the control contains a number that is more than 400, display an appropriate message. The statement that calculates the grade should pass the maximum number of points to the studentGrade object’s DetermineGrade method. Make the necessary modifications to the procedure. Save the solution and then start and test the application.
Celsius to Fahrenheit TableAssuming that C is a Celsius temperature, the following formula converts the temperatureto a Fahrenheit temperature (F):F =9/5C + 32Create an application that displays a table of the Celsius temperatures 0–20 andtheir Fahrenheit equivalents. The application should use a loop to display the temperaturesin a list box.
