Question | Answer |
---|---|

experiment | an activity whose results can be observed and recorded |

outcome | the result of an experiment |

probability | a number from 0 to 1 that tells you how likely something is to happen |

experimental probability | the ratio of the number of times the outcome happened to the number of times the experiment was repeated |

equally likely | outcomes are equally likely if they have the same chance of occurring |

event | a set of outcomes for a particular experiment |

theoretical probability | the ratio of the number of outcomes in the event to the total number of possible outcomes |

impossible event | an event that cannot happen. It has a probability of 0 |

certain event | an event that must happen. It has a probability of 1 |

divisible | when a number can be evenly divided by another number, it is divisible by that number |

factors | when a whole number is divisible by a second whole number, the second number is a factor of the first |

greatest common factor (GCF) | the greatest number that is a factor of each of two or more numbers |

prime number | a whole number greater than 1 that has exactly two two factors, 1 and the number itself |

composite | a whole number greater than 1 that has more than two factors |

prime factorization | a number written as the product of prime factors. A factor tree helps to find the prime factorization |

factor tree | (prime factorization) a number written as a product of prime factors. The structure drawn to help organize prime factorization |

power | (exponential form) a way o and a base is writing a number using exponents. A number that can be written using an exponent and a base is a power of the base |

exponent | a raised number that tells how many times a base is used as a factor |

base | a number that is the basis of each place value column in a number system |

standard form | a number written without using exponents |

exponential form | a way of writing a number using exponents |

ordered pair | the numbers that give the location of a point on a coordinate grid. The first number gives the horizontal position and the second number gives the vertical position |

coordinated grid | a grid formed using two number lines as axes. The axes intersect at the point (0,0) called the origin |

axes | real or imaginary reference lines (singular = axis). Graphs have horizontal and vertical axes |

origin | the point of intersection of the x and y axis on a coordinate or Cartesian plane. The coordinates of the origin are (0,0) |

variable | a letter or symbol that represents a quantity that is unknown or that can change |

evaluate an expression | to substitute a number for each variable, then carry out any operation in the expression |

equation | a mathematical sentence that uses the symbol “=” between two expressions to show that they have the same value |

multiple | a multiple of a whole number is the product of that number and any nonzero whole number |

least common multiple (LCM) | for two or more numbers, the least number in the list of their common multiples |
