The Language of Algebra. The language of Algebra uses numbers and variables. A variable is a symbol that can be replaced by any menber of a set of numbers or other objects. When numbers and variables are combibed using the operations of arithmetic, the result is called an algebraic expression, or simply an expression. The expression π r ^ 2 uses the variable r and the numbers π and 2.
Week 5 - Assignment Week Five Written Assignment Following completion of your readings, answer the following two questions from “Chapter 12 Supplement” of Mathematics in Our World. Select one even problem from exercises 1 through 10 on page 810. Select one even problem from exercises 11 through 22 on pages 811-812. As you answer the questions above, identify what types of misrepresentation or misuse have been demonstrated by referring to the bold blue headings in the “Chapter 12 Supplement” (e.g., Suspect Samples, Asking Biased Questions, Misleading Graphs, etc.). The assignment must include (a) all math work required to answer the problems as well as (b) introduction and conclusion paragraphs.

Pythagoras left the city of Croton when conflicts came about. He left to Metapontion, where he later died around 480 B.C. Pythagoras's name will always be around when we talk about math. His theorem will be taught in most all present and future math classes. His brotherhood and school will still be secret in a way because not much is known about it.
Assignment #2 1) Improve the result from problem 4 of the previous assignment by showing that for every e> 0, no matter how small, given n real numbers x1,...,xn where each xi is a real number in the interval [0, 1], there exists an algorithm that runs in linear time and that will output a permutation of the numbers, say y1, ...., yn, such that ∑ ni=2 |yi - yi-1| < 1 + e. (Hint: use buckets of size smaller than 1/n; you might also need the solution to problem 3 from the first assignment!) 2) To evaluate FFT(a0,a1,a2,a3,a4,a5,a6,a7) we apply recursively FFT and obtain FFT( a0,a2,a4,a6) and FFT(a1,a3,a5,a7). Proceeding further with recursion, we obtain FFT(a0,a4) and FFT(a2,a6) as well as FFT(a1,a5) and FFT(a3,a7). Thus, from bottom up, FFT(a0,a1,a2,a3,a4,a5,a6,a7)
Cooper's side B, no less complex, exudes a totally different different energy. Whereas Hodgkinson understands composition, Cooper clearly feels composition in a way that no amount of learning or study can approach. Every choice in her pieces exudes class; dissonance and atonality make their

INEQUALITIES 1 BMI Brandon Picone MAT 221: Introduction to Algebra Instructor: Gregory Dlabach Dec 2, 2013 INEQUALITIES 2 BMI and You For this assignment I will be demonstrating how you can find out how to use Inequalities to find whether or not you are overweight. You can use my equations and the examples of my work to find out exactly what category you might fall in. In this equation we are asked to use our own height to find out exactly if I might have a longer life span than the usual person. Before we get started, remember that W=my weight, and H=my height. W=176 and then H=65” In this first compound inequality, I had to take the equivalent inequality and replace it with
What is the value for the new sample New Sample Mean = 7 Explanation of work: When the data value is 19:mean = sum of values / # of value 9 = sum/7 sum = 7 x 9 = 63 When that data value is 5 the sum is 63-14 = 49 New mean = 49/7 = 7 7. Using Excel create a histogram and a line graph using the scores in the following table: Note: When you wish to plot one series (the column f in this problem) select only that column. Once you select the column, then you insert the column and line graph. Insert your histogram and line graph here: X 1 2 3 4 5 6 7 8 f 2 1 6 7 4 4 1 1 Line graph 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 f Histogram 8 6 4 2 0 f 1 2 3 4 5 6 7 8
Mathematics is a tool used to quantify something around us, and this quantification has been going on for years so which also says that mathematics isn't invented but it is discovered. The humans did not invent math, they just related it with our existing nature, they gave the mathematical concept for everything relating with numbers, angles, Multiplication, division, addition as well as subtraction. We can imply the 2-3 ways of knowing in such area, The predominant numbers that are represented by symbols is an invention, that is the language used in mathematics as a device to convey and utilize complex mathematical concept round the globe. Is Math discovered or invented? I personally feel that the correlation between a mathematical concept
