Terms in this set (96)
complement of an event
the probability of a non-occurrence of a desired outcome
compound event
a set of outcomes from a combination of activities where the outcomes can be subdivided (ex:flipping a coin and rolling a number cube, drawing tiles out of a bag or spinning a spinner)
dependent event
outcome of an action may be affecting the probability of the outcome of any following activity
data
information that is collected about people, events, or objects
event
a probable situation or condition
Experimental probability
the likelihood of an event occurring from the outcomes of an experiment
fundamental counting principle
multiplying the outcomes of events to get the total outcomes possible for both events
independent events
outcome from one action or activity that does NOT affect the outcome of any following activity
inference
a conclusion or prediction based on data
mutually exclusive events
events that cannot happen at the same time
law of large numbers
as the number of trials in an experiment increases, the experimental probability of an event approaches the theoretical probability of the same event, meaning the difference between the experimental and theoretical probability will be closer to zero
outcome
the result of an action or eventpopulation
population
total collection of persons, objects, or items of interest
probability
a ratio between the number of desired outcomes (what you are looking for) to the total possible outcomes
qualitative
a broad subjection description (types of likelihood)
quantitative
a narrowed objective description associated with numbers or a quantity
random sample
a subset of the population selected without bias in order to make inferences about the entire population
sample
a subset of the population selected in order to make inferences about the entire population
sample space
a set of all possible outcomes of one or more events
simple event
a set or subset of outcomes from a single action or activity where the outcomes cannot be subdivided
simulation
an experiment or model used to test the outcomes of an event
theoretical probability
the likelihood of an event occurring without conducting an experiment (prediction)
area
the measurement attribute that describes the number of square units a figure or region covers
circle
a two-dimensional figure formed by a closed curve with all points equal distance from the center
circumference
a linear measurement of the distance around a circle
composite figures
a figure that is composed of two or more two-dimensional shapes
diameter
a line segment whose endpoints are on the circle and passes through the center of the circle
Pi
the ratio of the circumference of a circle (equivalent to 3.14 or 22/7)
Polygon
a closed figure with at least 3 sides, where all sides are straight (no curves)
quarter circle
one-fourth of a circle
radius
a line segment drawn from the center of a circle to any point on the circle and is half the length of the diameter
radii
more than one radius
semicircle
half of a circle
two-dimensional figure
a figure with two basic units of measure, usually length and width
counting (natural) numbers
positive whole numbers starting at 1
whole numbers
positive whole numbers including 0
integers
positive and negative whole numbers, including 0
rational numbers
positive and negative whole numbers, fractions, percents, and decimals; any number that can be divided evenly; including 0
irrational numbers
numbers that cannot be divided evenly; includes non-ending decimals, square roots, and pi
sales tax
a percentage of money collected by a store (retailer), in addition to a good or service that was purchased, for the local government as required by law
income tax
a percentage of money paid on earned wages of an individual or business for the federal and/or state governments as required by law
net worth
the total assets of an individual after the liabilities have been settled or paid
strategy to multiply decimals
do not line up decimals, solve normally, count decimal place values in problem and move from the end of the product the same number of times to the left
strategy to divide fractions
Leave the first fraction alone, change the operation, and multiply by the inverse (reciprocal)
coefficient
a number that is multiplied by a variable
basic needs
minimum necessities
financial liability
an unpaid or outstanding debt
incentives
to entice consumers to purchase at a retailer or a specific item
coupon
an amount deducted from the total cost of an item
sale
a reduced amount or price of an item
strategy of subtracting integers
all signs behind the subtraction sign are switched, two negatives will make a positive number
rebate
an amount returned or refunded for purchasing an item or items
earned wages
the amount an individual earns over a given period of time
budget
a monthly or yearly spending and savings plan for an individual, family, business, or organization
simple interest
interest paid on the original principal in an account, disregarding any previously earned interest
compound interest
interest that is calculated on the latest balance, including any previously earned interest that has been added to the original principal
inequality

solution set
a set of all values of the variable(s) that satisfy the equation or inequality
straight angle
an angle with rays extending in opposite directions and whose degree measures 180 degrees
variable
a letter or symbol that represents a number
equation
a mathematical statement composed of algebraic and/or numeric expressions set equal to each other
expression
a mathematical statement composed of algebraic and/or numeric expressions; has no inequality sign
constant rate of change
a ratio when the dependent, y-value, changes at a constant rate for each independent, x-value
constant rate of proportionality
a constant ratio between two proportional quantities, y/x, denoted by the symbol k
principal
the original amount invested or borrowed
rate
a multiplicative comparison of two different quantities where the measuring unit is different for each quantity
ratio
a multiplicative comparison of two quantities
unit rate
a ratio between two different units where one of them is 1
expense
payment for goods and services
income
money earned or received
vertical angles
a pair of non-adjacent, non-overlapping angles formed by two intersecting lines creating angles that are opposite and congruent to each other
complementary angles
two angles whose degree measures have a sum of 90 degrees
supplementary angles
two angles whose degre measures have a sum of 180 degrees
congruent angles
angles whose angle measurements are equal
adjacent angles
two non-overlapping angles that share a common vertex and exactly one ray
subset of numbers
a set of which all the elements are contained in another set
percent
a part of a whole expressed in hundredths
constant
a fixed value that does not appear with a variable
linear relationship
a relationship with a constant rate of change represented by a graph that forms a straight line; passes through the origin; represented by y=kx
non-linear relationship
linear but does not pass through the origin; represented by y=mx+b
