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? .

You randomly survey students at your school about what type of books they like to read. The two-way table shows your results. Find and interpret the marginal frequencies.

\(\begin{array}{|c|c|}\hline & \text{Fiction} \\ \hline & \text{Likes} & \text{Dislikes} \\ \hline \text{Non Fiction} \\ \hline \text{Likes} & 26 & 22 \\ \hline \text{Dislikes} & 20 & 2 \\ \hline \end{array}\)

Q.) A student has six textbooks, each 4.0 cm thick and 30 N inweight. What is the minimum work the student would have to do toplace the books in a vertical stack, starting with all the books onthe surface of the table?

a) There are classes of 234 students, find the mean and standart deviation for the number born on the 4th of July. Ignore leap years.The value of the mean is \(\displaystyle\mu\) = (Round to six decimal places as needed)

Yhe value of the standart deviation is \(\displaystyle\sigma\) = (Round to six decimal places as needed)

b) In a class of 234 students, would two be an unusually high number who were born on the 4th of July? Would 2 be an unussually high number of individuals who were born on the 4th of July?

A. This result is unlikely because 2 is within the range of usual values.

B. No, because 2 is within the range of usual values.

C. Yes, because 2 is greater than the maximum usual value.

D. Yes, because 2 is below the minimum usual value.
