Week 2 Written Assignment (paper) The Body Mass Index (BMI) is a guide to assist people in determining if they may have a longer life span than average, which may be possible if they are not overweight, on the other hand they are probably overweight, or are obese. The intervals for each are from 17 to 22, 23 to 24.999, 25 to 29.9, and over 30 respectively. Notice that it is between 17 and 22. That is not inclusive but rather a compound inequality statement which is 17 30 which will be written as (30, +8). Anyway, my BMI will be calculated, and I will explain how I arrived at the results. Sometimes, a person’s BMI can be misleading, so reasons will be provided about why. Finally, there is an evaluation of the regions outside of the “probably not overweight” range by using the set and interval notations along with a simple graph of the regions. BMI = (703W) / H2 Where W = one’s weight in pounds, and Where H = one’s height in inches. We are asked to calculate four intervals based on our own height. My height is 65.35 inches. The specified intervals include three compounds “between” inequalities, and one regular inequality. Everywhere “BMI” shows up in the inequalities I will substitute the formula and solve the inequality for W to specify the weight ranges which fit each category for my height. The first interval shows that might have a longer life span than average. The compound inequality for this is: 17

Provide complete solutions to problems 3.16, 3.18, 3.21, and 3.36 from the textbook (4th ed.) on pages 103 -108 C. Refer to the Union Airways case on Personnel Scheduling in section 3.3 on page 75 to build your strategy for dealing with the following case. A bus company must provide drivers for buses. The schedule varies from hour to hour because of customer demand as shown in the figure. Time 0 on the figure represents midnight, and times are shown with a 24-hour clock starting at midnight. This is only an example schedule. You are to write a model for a general problem with parameters describing the demand for the each four-hour period. Driver requirements over a 24-hour period. There are three classes of drivers: part time drivers who work four hour shifts, full time drivers who work a continuous eight hour shifts, and split shift drivers who work four hours, are off four hours, and then return for another four hours of work. (a) Develop an algebraic model for the above situation that could be used to determine the minimum number of drivers that should be used. Your model must include complete definitions/illustrations of (i) decision variables, (ii) objective function, and (iii) the constraints. (b) Set up a spreadsheet model for your algebraic model in (a) then use the SOLVER module on Ms-Excel to solve it. (c) Provide a summary report of your recommendations and observations based on your work in (b).

Elementary Algebra Name Institution Affiliation Elementary Algebra Question 2 x = 3/2y +2 (Equation 1) 2x -3y = 9 (Equation 2) Substituting x in equation 2; 2(3/2y +2) -3y = 9 3y +4-3y = 9 4 =9 Therefore, because the equation has no solution, then it can be said that: (e)no solution, inconsistent system. Question 3 1/x + 1/y = 5/6 (Equation 1) 1/x- 1/y = 1/6 (Equation 2) Solution Substituting a=1/x and b=1/y then the linear equation will be a + b = 5/6 a –b = 1/6 Multiplying every element with the denominator, which is 6, we will have and add the two linear equations, 6a + 6b = 5 6a- 6b = 1 12a = 6 12a/12 = 6 a = ½ Substituting a =1/2 using the first equation then 6(1/2) + 6b = 5 3 + 6b = 5 6b = 5-3 6b = 2 b = 1/3 Since a =1/x the value of x will be ½ = 1/x then multiplying both sides 2x as a common factor; ½(2x) = 1/x (2x) x = 2 Also since b= 1/y, 1/3 = 1/y, then multiplying both sides by 3y as a common factor then, 1/3 (3y) = 1/y (3y) Y = 3 The value of x and y are 2 and 3 respectively. Solution c. (2, 3) Question 5 4x + 2 y +3z = 6 (Equation 1) 2x – 3y – 4z = -4 (Equation 2) 8x + 4y + 6z = 12 (Equation 3) Making x the subject of the equation 1, then x= 6-2y/4 -3z/4 which becomes x = 3/2-1/2y- 3z/4. Substitution for x in equation 2 then 2(3/2-1y/2-3z/4) -3y -4z = -4 3-y -3z/2-3y -4z = -4 3-4y – 11z/2 = -4 Multiplying every side by 2 which is the common factor, then 8y +11z = 14 (Equation 3) Substitution for x in equation 3 then 8(3/2-1/2y- 3z/4) + 4y + 6z = 12 4y - 6z + 4y + 6z = 12 8y = 12 y = 12/8 y = 3/2 The answer is b: The system is inconsistent as there are infinite solutions Question 8 [(3a2b3z-5) / 2a-3b-2z5)]-3 Solution Inversing the indices changes the power of -3 to 3. = [(2a-3b-2z5)/ (3a2b3z-5)] 3 = (8a-9b-6z15)/ (27a6b9z15) (following the law of indices on division, the powers are subtracted. = 8z30/27a15b15...
