- experimental probability
- the ratio of the number of times an event happens to the number of times the experiment is done
- percent of Change
- the ratio (amt.of change/original amt.) expressed as a percent.
- means of the proportion
- in the proportion a/b = c/d, b and c
- dependent events
- events that influence each other
- outcome
- the result of a single trial, like a roll of a number cube.
- sample space
- all possible outcomes
- unit rate
- a rate with a denominator of 1 (40 mi/1 hr)
- ratio
- a comparison of 2 numbers by division (a:b or a/b)
- extremes of the proportion
- In the proportion a/b=c/d, a and d
- scale
- the ratio of the distance in the drawing to the corresponding actual distance.
- compliment of an event
- all of the outcomes NOT in an event

- one half of the measuring unit for any measurement
- unit analysis
- converting from one unit to another
- percent of decrease
- when a value decreases from its original amount
- probability
- how likely it is that something will occur
- percent error
- the ratio of the greatest possible error and the measurement
- theoretical probability
- the ratio of the number of favorable outcomes to the number of possible outcomes if all outcomes have the same chance of happening.
- cross products
- In the proportion a/b = c/d, ad and bc
- rate
- a ratio of a to b where a and b represent quantities measured in different unit.
- percent of increase
- when a value increases from its original amount
- proportion
- an equation that states two ratios are equal
- event
- any outcome or group of outcome
- similar fiqures
- two figures that have the same shape but not necessarily the same size
- scale drawing
- an enlarged or reduced drawing that is similar to an actual object or place.
