Experimental probability

The ratio of the number of times the outcome happened to the number of times the experiment was reported.


An Event

is a set of outcomes for a particular experiment.


Certain Event

is when an event must happen is has a probability of 1


Impossible Event

is an event that can never happen it has a probability of zero


A Tree Diagram

is a diagram that organizes the possible outcome for an expirement.


Frequency

is a number of times something occuurs in a set of data


The Mean or Average

is found by taking the sum of the data divided by the number of data


The Mode

is the most occuring piece of data


The median

is the middle piece of data in a set of data in numerical order


The Range

of data is the difference between the greatest value and the smallest value in the data set


A Graph

is a visual display of informmation


The Xaxis

is the horizontal line on the graph


The Yaxis

is the vertical line on the graph


An ordered pair

is a pair of numbers used to indicate a position in a corrdinate grid

Algebra

is a branch of mathematics that uses variables to generalize the rulesof numbers and operations


A Variable

is a symbol or letter that represents a number that changes or is unknown


To evaluate an expression

is to substitute values for variables and perform the operations


An exponent

tells the number of times the base is multiplied


A general rule

is a rule that tellsyou how to find any term in a sequence


A sequence

is an ordered list of numbers or objects


The associative Property

says that regrouping numbers when you multiply or add then does not change the result


The Distributive Property

for multiplication over addition says that to multiply a sum you can multiply each addened and add the products (9x(4+3)=9x49x3 The distributive property of multiplication over subtraction says that to multiply a difference you can multiply each number and take the difference of the products (9x(43)=9x49x3.
