Ozark Furniture Company Patricia Diggs MAT 221 Introduction to Algebra Instructor Bridget Simmons April 29, 2013 The Ozark Furniture Company can only obtain at the most 3000 board feet of maple lumber. A classic Maple Rocker requires 15 board feet of maple lumber, while a Classic Maple Rocker requires 12 board feet of lumber. Write an inequality that limits the number of possible rockers of each type that can be made. First I will list the variables that I will use in the inequality: Let f= the number of classic rockers Let c=the number of modern rockers Seeing as a classic rocking chair uses 15 board feet of lumber, I will use 15f and because a modern rocking chair uses 12 board feet of lumber, I will use 12c. The amount of lumber which can be used is 3000 board feet because that is all the lumber the company can obtain.
If they want to cut this by a factor of three to get it down to $4000, they need to multiply the sample size by 3^2=9, and get a sample size of 25×9= 225. Here is how we can calculate it more directly. We want ME = 4000, and we know ME = 2×SE. Therefore, SE = ME/2 =2000, and also, SE = SD/Square root of sample size. So, 2000 = 30000/Square root of sample size.
p.286. no 10.- Two hundred draws will be made at random with replacement from the box -3, -2, -1, 0, 1, 2, 3 (a) If the sum of the 200 numbers drawn is 30, what is their average? (b) If the sum of the 200 numbers drawn is –20, what is their average? (c) In general, how can you figure the average of the 200 draws, if you are told their sum? (d) There are two alternatives: (i) Winning $1 if the sum of the 200 numbers drawn is between –5 and +5 6 Winning $1 if the average of the 200 numbers drawn is between –0.025 and +0.025.

Problem #35 • This sequence is arithmetic • The cost to build the tower is $1800. STEPS/CALCULTATIONS YOU PERFORMED TO REACH THE ANSWER: The common difference in this sequence is $25, thus making it an arithmetic sequence. The formula for finding the final term is an = a1 + (n-1)d. In this problem, n=9 for the 9 sections of 10 foot sections, a1=100 since that is the first term of the sequence, and d=25 for the common difference. An = a1 + (n-1)d A9 = 100 + (9-1)25 A9 = 100 + (8)25 A9 = 100 + 200 A9 = 300 So the final term of the sequence is 300. Now that we know this, we can find the sum of the terms to calculate the final cost.

The only way they will ever know how to make a decision is to weigh the pros and cons of any choice on paper. The Stampede Electric RC Monster Truck vs. The Nitro RC Monster Truck. The Traxxas Electric Stampede #3605 Electric driven Monster Truck costs $219.99 +tax for a total of $235.39.
The first thing I did was multiplied all the terms by H^ in order to remove the denominator. I then divided all the terms by 703 to isolate the W. My height was then added in order to find out the second weight interval (4096). Multiplication and division were then performed. Those of people whom may weigh between 134lbs and 145.6lbs are most likely not over

Body Mass Index Jacob Shearer MAT221 Introduction to Algebra Instructor Pamela Clarke November 17, 2013 I am going to solve the following 4 formulas involving Body Mass Index starting with the first one. 17<703WH^2<22 This is the equivalent inequality where I substituted BMI with the formula. Then I replace the H^2 with my height in inches. 17<703W73^2<22 After factoring in my height to the second power I get 17<703W5329<22 Now I multiply all 3 terms by the denominator 17(5329) < 703W(5329)5329 <22(5329) and then get 90593 < W < 117238. Then finally I divide all 3 by 703 in order to isolate W. 128.8 < W < 166.7 So people with the height of 73 inches could have a longer than average life span if they weigh between 129 and 167 pounds.
