Terms in this set (88)
absolute Value
The distance a number is from zero on the number line
Acute Angle
An angle that is less than 90 degrees
Additive Identity
..., A number + 0 = that number
Additive inverses
..., An integer and its opposite (for example, -4 and 4); -a + a = 0
algebraic equation
..., a number sentence that contains an equal sign and algebraic expressions - ex. y + 2 = 5
algebraic expression
..., A mathematical sentence that includes at least one operation and a variable. Simplify not solved
algebraic rule
..., a mathematical expression that contains variables and describes a pattern or relationship
angle
..., A figure formed by two rays with a common endpoint
area
..., A measure of how much surface an object has
associative property
..., Changing the grouping of numbers will NOT change the value. For example: (7 + 4) + 8 = 7 + (4 + 8) also works with multiplication
axes
..., The two perpendicular number lines on a coordinate graph
base (geometric)
..., the line segment or face of a geometric figure that is perpindicular to the height
Bivariate data
..., Data with two variables
box plot
..., A graph that displays the highest and lowest quarters of data as whiskers, the middle two quarters of the data as a box, and the median
circumference
..., The distance around a circle
commutative property
..., The order of two numbers may be switched around and the answer is the same. ex 2+3= 3+2
complementary angles
..., Two angles whose sum is 90 degrees
congruent
..., Equal
coordinate grid
..., a grid formed by a horizontal line called the x-axis and the vertical line called y-axis
coordinate
..., An ordered pair of numbers that identifies a point on a coordinate place, written as (x,y)
Dilation
..., A transformation that stretches or shrinks a figure to create a similar figure.
Diameter
..., A straight line passing from side to side through the center of a circle or sphere.
difference
..., Answer to a subtraction problem
distributive property
..., A(B+C) = AB + AC so A is the coke man to multiply by B and C
empirical probability
..., involves conducting an experiment to observe the frequency with which an event occurs
equilateral triangle
..., A triangle with three congruent sides
equation
..., A mathematical sentence that contains an equals sign.
equivalent expressions
..., expressions that have the same value
expression
A mathematical phrase that contains operations, numbers, and/or variables.
face
a side of a 3-d object
first quartile
the median of the lower half of the data set
function
A relation between sets of input and output where each input is related to one and only one output. The lobster model of mathematics.
function table
a table organizing the input, rule, and output of a function
hypotenuse
the longest side of a right triangle
inequality
A mathematical sentence that contains less than, greater than, less than or equal to, greater than or equal to, or not equal
integer
All whole numbers (both positive and negative) and zero.
intercept
The point where the graph of a function crosses the x-axis or y-axis.
interquartile range
The difference between the upper and lower quartiles.
inverse operation
Operations that undo each other
mean
A measure of center in a set of numerical data, computed by adding the values in a list and then dividing by the number of values in the list.
median
Middle Number
multiples
numbers you say when you skip count. Multiples of 2 are: 2,4,6,8,...
multiplicative identity

origin
the point (0,0) where the x-axis and the y-axis intersect in a coordinate plane
parallel lines
lines in the same plane that never intersect
perpendicular
Intersecting at or forming right angles
perimeter
The distance around a figure
pi
3.14 rounded.
polygon
A closed figure formed by three or more line segments
product
The answer to a multiplication problem
proportion
An equation stating that two ratios are equal.
Pythagorean theorem
a² + b² = c² to find missing side of right triangle
quadrant
one of four sections into which the coordinate plane is divided
quotient
the answer to a division problem
radius
A straight line from the center to the circumference of a circle or sphere.
range
Distance between highest and lowest scores in a set of data.
rate
A ratio that compares two quantities measured in different units
ratio
a comparison of two or more quantities
rational number
A number that can be written as a fraction
ray
