URGENT San Luis Obispo High School is planning a cake sale. Supplies for the cake sale are going to cost the school $190, and they can bake at most 350 cakes. Write a linear function where the profit, P, from the fundraiser is a linear function of the number of cakes, N, sold. Find the domain and range of the function when the price of each cake is $15.

F(x)= 1/x-4, g(x)=4x+1/x a. use composition to prove whether or not the functions are inverses of each other. b. express the domain of the compositions using interval notation.

In the diagram below, tan θ = sqrt 3. what is the value of m?

Jeffery conducted a survey in his school and found that 30 of the 50 eighth grade students' favorite subject is mathematics. based on the results, jeffery concluded that out of the 200 students in his school, 120 students' favorite subject is mathematics. select the statement that is true about jeffery's conclusion. a. jeffery's conclusion is not valid because the sample was biased since only 200 students were surveyed. b. jeffery's conclusion is valid because the sample was random since all of the students were eighth grade students. c. jeffery's conclusion is valid because the sample was random. d. jeffery's conclusion is not valid because the sample was biased since all of the students were eighth grade students.
