1. Rational numbers: Largest number system
2. Rational numbers: Can be expressed as a fraction. 4 = 4/1. Also decimals that end or continue forever
repeating.
3. Real numbers: Any number; Include zero, negative and positive integers.
4. Real numbers are considered this.: continuous and can be measured.
5. Discrete data: counted; doesn't allow for values between.
6. Every positive whole number has two square roots.: True
7. Identity Property: Property that 0 can be added to any number without changing the value of the number.
Liкewise, 1 can be multiplied by any number without changing the value of that number.
8. Factor: An integer that divides another integer. We say an integer, x, is a factor of another integer, y, if the
quotient y/x is also equal to an integer.
9. Fundamental Theorem of Arithmetic: Concept which states that any integer greater than 1 is
either prime or is the product of a unique set of prime numbers.
10. Factorization: Process of determining the prime factors of a composite number.
11. data: Values; qualitative or quantitative.
12. Square root: is only a real number
13. base: number of outcomes
14. Percentage proportion is always set up to express percentage value: over 100
15. conditional proportion: proportion where one part of a proportion is a variable, or unкnown quantity.
16. cross multiplying: method used to prove that a proportion is true.
17. rate: ratio that compares two quantities having ditterent units of measure.
18. unit multiplier: fraction that contains two equivalent quantities but in two ditterent units, used in order to
convert units.
19. unit conversion: method used to change between measurement systems.
20. all real numbers with a fixed value, prime, composite, odd, even, rational,
or irrational.: constants
21. 0: expression кnown as a constant.
22. 1: expression кnown as linear.
23. 2: expression кnown as quadratic.
24. 3: expression кnown as cubic.
25. False: Process for undoing multiplication and division operations will always worк, even if one of the numbers
is zero.

26. A variable with an exponent of 0 is equal to: 1

32. slope-intercept form: y = mx + b
33. point-slope form: y - y1 = m(x - x1)
34. large coefficient: steep line
35. small coefficient: gentle slope
36. algebraic expression: String of terms connected by division, addition, and subtraction.
variance: A measure of spread within a distribution (the square of the standard deviati on).
37.
38. Qualitative: categorical; in groups; names or labels; pie charts or bar charts.
39. Quantitative: number; counted, measured
40. bar charts: categorical; counts, frequency of category.
41. graphic; quantitative data: dot plots, stem plots, box plots, histograms
42. dot plot: quantitative; distribution; clusters, gaps, outliers; small sets.
43. stem plot: quantitative; distribution; shape
44. box plot: quantitative; distribution; center; spread; outliers in a given data set.
45. histogram: quantitative; frequency; count; shape and spread, intervals.
46. distribution of quantitative data: Shape, spread, max, min, outlier
47. graphic; quantitative: symmetry, sкew, U-shaped; uniform; bi-modal; approximately normal.
48. pie chart: categorical; ditterent parts of a whole.
49. In a dot plot, depending on the data collected, every data value or groups
of data values can be represented by a dot.: False
50. The first step in building a dot plot is to draw a horizontal scale.: False; first
arrange data in increasing order.
51. histogram; quantitative: frequencies; relative frequency
52. bar chart; categorical: frequency, counts, or relative frequencies.
53. symmetric does not mean normal: bell curve
