Experimental probability
probability based on the repeated trials of an experiment
Rate of change
the relationship between two quantities that are changing, this is also slope
mean
an average of n numbers computed by adding some function of the numbers and dividing by some function of n
median
relating to or situated in or extending toward the middle
mode
the most frequent value of a random variable
range of data
The range is from the lowest value to the highest value. Eg. The range of ages in year 11 is from 15 to 17.
linear function
y=x or f(x)=x
slope
rise over run
parallel
lines in the same plane that do not intersect
perpendicular
intersecting at or forming right angles
x-intercept
x coordinate of a point where a graph crosses the x axis/ y coordinate of this point is zero
y-intercept
the y-coordinate of a point where a graph crosses the y-axis
standard form of linear equation
Ax+By=C, C over B gets you the y intercept, C over A gets the x intercept, and B over A gets the slope. rules=leading coeffecient (A) cannot be negative. Cannot be a fraction. MUST be in the exact form.
slope-intercept form of linear equation
y = mx + b, where "m" is the slope of the line and "b" is the y-intercept.
system of linear equations
set of two or more equations with two or more variables
equation
A mathematical sentence that uses an equal sign
Inequality
A mathematical sentence that contains less than, greater than, less than or equal to, greater than or equal to, or not equal
coefficient
A number multiplied by a variable in an algebraic expression.
term
The parts of an expression that are added or subtracted
function
A relation in which every input value has a unique output value.
domain
the set of values of the independent variable for which a function is defined
range (of a function)
the set of all the values of the dependent variable or the y-coordinate
transformation
(mathematics) a function that changes the position or direction of the axes of a coordinate system
translation
(mathematics) a transformation in which the origin of the coordinate system is moved to another position but the direction of each axis remains the same
reflection
(mathematics) a transformation in which the direction of one axis is reversed
dilation
a transformation that enlarges or reduces a figure
similar
Figures that have the same shape but not necessarily the same size
proportion
an equation stating that two ratios are equal
integer
The set of whole numbers and their opposites
theoretical probability
the ratio of the number of ways an event can occur to the number of possible outcomes
