A uniform distribution always takes on the same value, a unimodal distirbution has one peak, while the bimodal distribution has two peaks. A symmetric distribution has the most values in the middle, while a skewed distribution will have the most value to the left or the right. a) Uniform and Symmetric, because most will be the same age. b) Unimodal and skewed, because most will have 0,1 or 2 siblings, but some might have more. c) Unimodal and symmetric, because most of the pulse rates will take on about the same average value, some will have a lower pulse rate and some a higher pulse rate. d) Uniform and Symmetric, because the number of time each face shows should be about the same.

A city recreation department offers Saturday gymnastics classes for beginning and advanced students. Each beginner class enrolls 15 students, and each advanced class enrolls 10 students. Available teachers, space, and time lead to the following constraints. ∙∙ There can be at most 9 beginner classes and at most 6 advanced classes. ∙∙ The total number of classes can be at most 7. ∙∙ The number of beginner classes should be at most twice the number of advanced classes. a. What are the variables in this situation? b. Write algebraic inequalities giving the constraints on the variables. c. The director wants as many children as possible to participate. Write the objective function for this situation. d. Graph the constraints and outline the feasible region for the situation. e. Find the combination of beginner and advanced classes that will give the most children a chance to participate. f. Suppose the recreation department director sets new constraints for the schedule of gymnastics classes. ∙∙ The same limits exist for teachers, so there can be at most 9 beginner and 6 advanced classes. ∙∙ The program should serve at least 150 students with 15 in each beginner class and 10 in each advanced class. The new goal is to minimize the cost of the program. Each beginner class costs $500 to operate, and each advanced class costs $300. What combination of beginner and advanced classes should be offered to achieve the objective? .
