Name the four areas in which standards of ethical conduct exist for management accountants in the United States. What organization sets forth these standards?

A teacher records the scores on a project and wants to group the data in intervals of 5 points. Should the teacher use a stem-and-leaf plot or a histogram? Explain.

How does a balance arise in the Purchase Discounts Lost account? Why does management pay careful attention to the balance (if any) in this account?

Use the graphical method to solve each linear programming problem.

$$\begin{array}{lr} \text { Maximize } & z=2 x+4 y \\ \text { subject to: } & 3 x+2 y \leq 12 \\ & 5 x+y \geq 5 \\ & x \geq 0 \\ &y \geq 0 \end{array}$$

If you want your microscope or telescope to project a real image onto a screen, how would you change the placement of the eyepiece relative to the objective?

The hexadecimal numeration system, used in computer programming, is a base sixteen system that uses the symbols $0,1,2,3,4,5,6,7,8,9$, $A, B, C, D, E,$ and $F.$ Change each of the following hexadecimal numerals to base ten numerals.

b. $1 \mathrm{C} 2 \mathrm{~B}_{\text {sixteen }}$

Jaclyn bought some decorative letters for a scrapbook project. If she selected a permutation of the letters shown, what is the probability that they would form the word "photography"?

For each sentence below, underline the word or words in parentheses that correctly complete the sentence.

Will you follow Dwayne's (advice, advise) about your project?

One constraint to a linear programming problem is $8 x_{1}+5 x_{2}+s_{2}=59$ This constraint determines a boundary line to the feasible region. (a) Is the point (3, 7) on the boundary line? (b) Can (2, 4) be in the feasible region?

Solve the linear programming problem. Assume $x \geq 0$ and $y \geq 0$.

Maximize $C=2 x+6 y$ with the constraints

$$\left\{\begin{array}{r} x+y \leq 12 \\ 3 x+4 y \leq 40 \\ x+2 y \leq 18 \end{array}\right.$$

Elizabeth Jablonski is the director of Research and Development for Galaxy Electronics. Last week, she submitted the following funding request as part of the annual budget process.

The aircraft guidance system is a project the company has publicly announced and is marketing strongly to manufacturers. The miniature DVD project has received little support in the company but is one of Elizabeth’s favorites. The chief fi nancial offi cer requests all groups to revise their budgets because of lower than expected sales for the company. Department heads have been asked to submit new budgets that are 10 percent below their original submissions.

Learning the company’s commitment to the aircraft guidance system, Elizabeth submits the following revision noting that it is 10 percent lower as requested.

Required
What do you think Elizabeth is trying to accomplish with the revised request? Is this ethical?

In Programming Challenge 9 of Chapter 4 you wrote a population class that predicts the size of a population of organisms after a number of days. Modify the class so it uses a recursive method instead of a loop to calculate the number of organism.

Use the constraints below to solve each linear programming problem.

$$\left\{\begin{array}{rcl} x & +2y & \leq 40\\ 2 x & +y & \leq 40\\ x&+y & \geq 10 \\ & x & \geq 0 \\ & y & \geq 0 \end{array}\right.$$

Minimize $z=5x+2y$.

the linear programming problem has an unusual characteristic. Sketch a graph of the solution region for the problem and describe the unusual characteristic. Find the minimum and maximum values of the objective function (if possible) and where they occur. Objective function: z = x + y, Constraints: x ≥ 0, y ≥ 0, -x + y ≤ 0, -3x + y ≥ 3
