(Instant Download) Question: Discrete data Has distinct values, can be counted, had unconnected points (think dots) Question:Continuous data Has values within a range, measured not counted, does not have gaps between data points (data is connected lines or curves). Question:Example of discrete data Days of the week Question:Expressions A group of symbols such as numbers and operators that has mathematical validity Question:Commutative The order in which the numbers appear in the sum can be reversed Question:Identity property Adding 0 to any number does not change the original number Page | 2 Question:Additive inverse Values that are equally far from 0 on the number line. Question:Negative When multiplying a positive number by a negative number the result is always Question:Positive Multiplying a negative number by a negative number results in a positive Question: Factors Integers that evenly divide the initial integer Question: Prime number Positive integer with exactly two positive factors consisting of 1 and itself Question: Composite number Has at least one positive factor other than one and itself Question: Factorization Process of breaking up a composite number into its prime factors Question: fundamental theorem of arithmetic Page | 3 Any integer greater than one is either Prime or the product of Prime numbers Question:Principal square root Positive square root of a number Question:Radican Number under radical sign √16=4 Question:Open Circle Represents less than or greatest than on the number line Question:Perfect square Product of any integer with itself yields a perfect square. Question:Whole numbers positive numbers with a whole value Question:Integers Numbers with no fractions or decimal value but can be positive or negative Question:Rational numbers Numbers that can be expressed as a fraction or decimal values that have that end or repeat forever. Includes all integers since all integers can be expressed as fractions. Page | 4 Question:Real numbers Everything that can be included in a number line including pi. Question:Fractions Express numbers which are part of a whole Question:Numerator Number written before the slash or above the fraction bar Question:Proper fraction Numerator is less than denominator and the value of the fraction is less than one Question:Improper fraction Numerator is greater than denominator and therefore is greater than one except with negative fractions Question:Mixed numbers A whole number and proper fraction. A negative sign in front applies to both parts of the mixed number. Question:Multiples Integers created by multiplying one number times another number Question:Fractions Express numbers which are part of a whole Page | 5 Question:Numerator Number written before the slash or above the fraction bar Question:Proper fraction Numerator is less than denominator and the value of the fraction is less than one Question:Improper fraction Numerator is greater than denominator and therefore is greater than one except with negative fractions Question:Mixed numbers A whole number and proper fraction. A negative sign in front applies to both parts of the mixed number. Question:Multiples Integers created by multiplying one number times another number Question:Reciprocal The number which of multiplied by divisor gives you one (like the fraction flipped over) Question:Terminal decimal Has digits that end Question:Ratio Comparison of two numbers Page | 6 Question:Rate A ratio that compares two quantities having different units of measure Question:Proportion True statement in which two ratios are equal to each other. Two days are proportional of they are equivalent. Question:Conditional proportion One part of a proportion is a variable or unknown quantity Question:Celsius to Fahrenheit Celsius x 9/5 + 32 Question:Fahrenheit to Celsius (Fahrenheit - 32) x 5/9 Question:Constant Number with a fixed value. All real numbers are constants Question:Elementary operations Addition, subtraction, multiplication, division Question:Base The number an exponent is written next to Page | 7 Question:Variable Symbol that represents our holds the place of a numerical value Question:Coefficient A number by which a variable is being multiplied. Coefficients are written in front of variables. 16x, 16 is coefficient. If there is no number you assume an invisible1. Question:Term Can be a single constant, a single, or a number of constants and variables multiplied together. Question:Algebraic expression String of terms connected by division, addition, and subtraction. Question:How to write an algebraic expression Constants at end. Write terms with the largest exponents first. Always write in descending order of exponent value with constants at the end. Question:Inverse operation Operations that undo each other. Subtraction is inverse of addition. Division is inverse of multiplication. Question:Like terms Have the same variable with the same exponent Question:Degree of an expression Page | 8 Refers to largest exponent in an expression Question:Linear Has degree of 1 Question:Quadratic Has degree of 2 Question:Cubic Has degree of 3 Question:Constant Has degree of 0 Question:Distributive property Principle used to multiply a single term by multiple terms. If there are parenthesis around multiple terms which are in turn multiplied by a single term, we can use this property. Question:Histogram A graphical representation -- bars, measuring the frequency within each interval Question:Skewed right Not a symmetric distribution, the tail is on the right Question:Measures of center Page | 9
