Three instructors, Ms. Busby, Mr. Butler, and Mrs. Hutchison, assign projects in their precalculus classes. Some students use graphing calculators with their project, and some do not. The
following table summarizes the number of students in each type of project:

- Refer to the diagram showingarrow_forwardb. Number of boys and girls in each block: Let's say you want to graph the number of boys and girls in each grade level in a school. You have five grade levels: kindergarten, first grade, second grade, third grade, and fourth grade. In kindergarten, there are 15 boys and 10 girls. In first grade, there are 20 boys and 18 girls. In second grade, there are 12 boys and 14 girls. In third grade, there are 16 boys and 20 girls. In fourth grade, there are 18 boys and 16 girls.Make an appropriate graph for this situation in EXCELShow the steps on how you made itarrow_forwardMap the nodesarrow_forward
- Assume that you are an employee in a Pizza Bakery and are given a list of ingredients that can be used in a pizza along with a list of their costs and sell prices. The index of an ingredient in the ingredient list is the same as its cost index in the costs list and its price index in the price list. The inputs look like this:Ingredients = {Cheese, Tomato, Basil, Green Pepper, Salami, Ham, Bacon, Olive}Costs = {2 , 1 , 1 , 1.5 , 3 , 4 , 8, 1}Price = {3 , 2 , 0, 0.5 , 1 , 7 , 7 , 1.5}We can say that Cheese costs $2 and if a pizza contains cheese we charge an additional 3$. Unfortunately, your manager is kind of an annoying person and puts a rule which as follows: If a customer asks for ingredient index x and ingredient index y where x < y, the customer must add the other ingredients between index x and y.For example, if a customer asks for Basil and Ham, the customer must also buy Green Pepper and Salami.The manager tells you to write a program that finds the sequence of ingredients…arrow_forwardGraph A, B, C, D, and Earrow_forwardWhat program did you use to type in your code to create the graph?arrow_forward
