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 |
