18. MODELING WITH MATHEMATICS The function y = 3.5x + 2.8 represents the cost y (in dollars)
of a taxi ride of x miles.
a. Identify the independent and dependent variables.
b. You have enough money to travel at most
20 miles in the taxi. Find the domain and
range
of the function.

Solve for x, y, and z. show all steps.

Just tell me how to set up the equation.

Using pert, adam munson was able to determine that the expected project completion time for the construction of a pleasure yacht is 21 months, and the project variance is 4. a) what is the probability that the project will be completed in 17 months? b) what is the probability that the project will be completed in 20 months? c) what is the probability that the project will be completed in 23 months? d) what is the probability that the project will be completed in 25 months? e) what is the due date that yields a 95% chance of completion?
