any number less than zero, they are written with a negative sign (example: -2, -1)

Front 16

Odds

Back 16

the probability (chance) that some event will occur. (example: when rolling a die, the odds of rolling a 2 are 1 out of 6 or 1/6)

Front 18

Pi

Back 18

the ratio of the circumference of a circle to its diameter. (about 3.14)

Front 19

Poll

Back 19

a sampling or collection of opinions on a subject, taken from either a selected or a random group of persons, as for the purpose of analysis.

Front 20

Power (of a number)

Back 20

the number of times a number is used as a factor. Represented by an exponent. (example: 23 = 2 x 2 x 2 = 8 or 2 to the third power)

Front 21

Prime Factorization

Back 21

a composite number written as the product of its prime factors. (example: 3 x 3 x 2 = 18)

Front 22

Protractor

Back 22

a tool used to measure angles

Front 23

Pyramid

Back 23

a three dimensional figure that has any polygon for its base and triangles for all other faces

Front 24

Qualitative Graph

Back 24

representations that focus on the important general features of a situation, a graph of data that can be observed but not measured such as colors, scents, smells.

Front 25

Random

Back 25

an event that happens by chance (example: whether a tossed coin lands on heads or tails)

Front 26

Rate

Back 26

a ratio that compares two quantities with different kinds of units (example: 3 pens for $1.19 where the items (pens) are one kind of unit and money ($1.19) is a different kind of unit.

Front 27

Ratio

Back 27

the comparison of two quantities using a fraction or division (example: Two people are riding on an elephant. The ratio of people to elephants is 2:1). Ratios can be written two ways: a/b or a:b.

Front 28

Repeating Decimal

Back 28

a decimal number with a digit or a group of digits that repeat on and on, without end. When writing a repeating decimal, a bar is placed over the repeating portion. (example: 1/3 expressed as a decimal is 0.3333333…….. or 0.

Front 29

Sample Bias

Back 29

created when a person who does a study that omits evidence that contradicts one particular outcome, by accidental design, as opposed to by choice. (When the data is omitted deliberately, that is known as selection bias)

Front 30

Sample Space

Back 30

Consists of all of the possible outcomes of a probability experiment (example: when a coin is tossed, there are two possible outcomes: heads and tails. The sample space is then {heads, tails})

Front 31

Scalene

Back 31

a triangle in which all three sides are a different length

Front 32

Similarity

Back 32

the condition of being similar (having the same shape, but different sizes)

Front 33

Simple events

Back 33

a single event in a probability problem (example: the tossing of one coin)

Front 34

Simulation

Back 34

a model of an experiment

Front 35

Theoretical Probability

Back 35

the likeliness of an event happening based on all the possible outcomes

Front 36

Triangle

Back 36

a plane shape that has three sides and three angles.
