ProbabilityA number from 0 to 1 that tells how likely an event is to happen.
i.e. What is the probability that I will get "heads" when I flip a coin?
1 out of 2, 50%, 0.5, 1:2, 1⁄2ProportionAn equation that states that two ratios are equivalent.
i.e. 5 = 25
12 60RangeThe difference between the greatest data value and the least data value in a data set. i.e. Find the range of the following data: 12, 45, 32, 15, 40, 25, 29, 49, 22, 27, 31, 33, 31
The largest data item is 49. The smallest data item is 12. Subtract the two: 49 - 12 = 37. Therefore the range is 37 for this data set.Rational NumberAny number that can be expressed as a ratio of two integers.
i.e. 6 can be expressed as 6, and 0.5 as 1.
12Scientific NotationA number that is written as the product of a decimal greater than or equal to 1 and less than ten and a power of 10.
i.e. Write 6,224,000,000,000 in scientific notation. 6.224 • 1012Zero Product PropertyThe product of any number and zero equals zero.
i.e. 3•0=0Compatible numbersNumbers that can be divided evenly; useful in estimating quotients
Ex. 27.2÷4.14 ≈ 28÷4=7...28and4arecompatible#s.ReciprocalA number that can be multiplied by another number to make 1 (numerator and denominator
are switched)
Ex. is the reciprocal of because
× = 1PercentA ratio that compares a number to 100
Ex. 25% is a percent that represents ( ).SequenceA set of numbers that follow a pattern Ex. 4, 6, 8, 10, 12...is a sequence of numbers.arithmetic sequenceA sequence where each term is found by adding or subtracting the exact same
number to the previous term
Ex. 4, 6, 8, 10, 12...is an arithmetic sequence (add 2)Geometric sequence -A sequence where each term is found by multiplying or dividing by the exact
same number to the previous term
Ex. 2, 6, 18, 54, 162...is a geometric sequence (multiply 3)Grouping SymbolsEx. (parenthesis), [brackets], {braces}, long division barOrder of OperationsThe procedure to follow when simplifying a numerical expression
1 - Grouping symbols
2 - Exponents
3 - Multiplication and Division (from left to right) 4 - Addition and Subtraction (from left to right)Numerical ExpressionA mathematical phrase that contains numbers and operation symbols
Ex. 14+8÷4-21Variable ExpressionA mathematical phrase that contains variables, numbers, and operation
Ex. 45-(x+3y)EvaluateTo replace variables with numbers and then simplify an expression
Ex. To evaluate 4x + 10 when x = 3, replace "x" with 3 and simplify: 4(3)+10=12+10=22Absolute ValueThe distance a number is from zero on the number line
Ex. |-3| = 3; "The absolute value of -3 is 3."OppositesPairs of numbers that have the same absolute value Ex. 4 and -4 are opposites because they are 4 units from 0X-axisThe horizontal number line that, together with the y-axis, establishes the coordinate planeY-axisThe vertical number line that, together with the x-axis, establishes the coordinate planeCoordinate PlaneA plane formed by two number lines (the horizontal x-axis and the vertical y-axis)
intersecting at their zero pointsQuadrantOne of four sections on the coordinate plane formed by the intersection of the x-axis and the y-axisOrdered PairA pair of numbers that gives the location of a point in the coordinate plane. Also referred to
as the "coordinates" of a point
Ex. The ordered pair (3, 2) describes the location that is found by moving 3 units to the right of zero on the x-axis and then 2 units up from the x-axis.OriginThe intersection of the x-axis and the y-axis on the coordinate plane
Ex. The origin is described by the ordered pair (0,0).X-COORDINATEThe number that indicates the position of a point to the left or right of the y-axis
Ex. The 4 in (4,3) is the x-coordinate, and tells you to move 4 places to the right of the y-axisY-CoordinateThe number that indicates the position of a point above or below the x-axis
Ex. The 3 in (4,3) is the y-coordinate, and tells you to move 3 places above the x-axisEquationA mathematical sentence that uses an equals (=) sign to indicate that the side to the left of the equals sign has the same value as the side to the right of the equals sign
Ex. Theequationx+4=10hasasolutionofx=6Inverse OperationsOperations that undo each other
Ex. Addition and subtraction are inverse operations. Multiplication and division are also inverse operations.INEQUALITYA mathematical sentence that uses a symbol (<, >, ≤, ≥, ≠) to indicate that the left and right
sides of the sentence hold values that are different Ex. The inequality x > 8 has an infinite number of solutions.PerimeterThe distance around the outside of a figure
Ex. The perimeter of a rectangle whose length is 18 feet and width is 5 feet is: 18+5+18+5 = 46 feet.CircumferenceThe distance around a circle
Ex. The circumference of a circle whose radius is 4 inches is: 2π(4) = 8π inches or approximately 25.12 inches.AREAThe number of square units inside a 2-dimensional figure
Ex. The area of a rectangle whose length is 18 feet and width is 5 feet is: 18×5 = 90 square feet.RadiusA line segment that runs from the center of the circle to somewhere on the circle
Ex. OA is a radiusRATIOA comparison of two quantities by division
Ex. The ratio of students to faculty members at a given university is 16:1 (also 16 to 1...or 16/1).Unit rateA rate that has a denominator of 1
Ex. The unit rate describing his speed was 14 meters per second.PROPORTIONA statement (equation) showing two ratios to be equal
Ex. = is a proportion.TERMA number, a variable, or product of a number and a variable(s)
Ex. There are 3 terms in the expression: 4x + y + 2ConstantA term with no variable part (i.e. a number)LIKE TERMSTerms with the same variable part (including exponent)...like terms can be combined using
the distributive property in reverse Ex. 4x+6x=(4+6)x=10xDISCOUNTThe amount by which a price is decreased
Ex. If shoes marked at $56 have a discount of $10, the new price is now $46.MarkupThe amount by which a price is increased
Ex. If the jacket was purchased at $25 from the manufacturer, and a $50 markup is applied, the new price is $75.DIAMETERA chord that passes through the center of the circle R
Ex. RS is a diameterCHORDA line segment that runs from somewhere on the circle to another place on the circle
OA
Ex. AB is a chordCentral Tendency -An attempt to find the "average" or "central value" of a given set of data.
Ex. In statistics, there are three main measures of central tendency: MEAN, MEDIAN, MODERADIUSA line segment that runs from the center of the circle to somewhere on the circle
Ex. OA is a radiusDIFFERENCEThe result of subtraction.Expanded NotationPointing out the place value of a digit by writing a number as the digit × its place value. For example, 342 = (3 × 102 ) + (4 × 101) + (2 × 10).Factor (noun)A number or symbol that divides evenly into a larger number. For example, 6 is a factor of 24.Greatest Common Factor (GCF)The largest factor common to two or more numbers.Least Common Multiple (LCM)The smallest multiple that is common to two or more numbers.Lowest Common Denominator (LCD)The smallest number that can be divided evenly by all denominators in the problem.Multiplicative InverseThe reciprocal of a number. Any number multiplied by its multiplicative inverse equals 1.POWERA product of equal factors. 4 × 4 × 4 = 43, reads "four to the third power" or "the third power of four." Power and exponent are some× used interchangeably.Prime NumberA number that can be divided by only itself and one.QuotientThe result of division.CoefficientA number that multiples a variableDeductive ReasoningReasoning logically from given facts to a conclusion
