Applied Probability and Statistics – C955 Flashcards
continuous
A collection of numbers whose values are not dividable into distinct units.
subtraction
Taking one or more values away from another.
associative property
The associative property holds that under certain operations in a multi-step expression, the computations may be done in any order. Commonly represented as (a + b) + c = a + (b + c). Addition and multiplication are associative.
composite number
A number with more factors than just one and itself.
principal square root
The positive square root of a number. For example, the principal square root of 36 is 6.
negative number
A number whose value is less than zero. On the number line, negative numbers are to the left of zero.
multi-step expression
An expression or equation with more than two values and two or more operators that requires multiple steps to be solved.
prime number
A number with only two factors: one and itself
multiplication
In mathematics, multiplication is the act of adding the same number multiple times. Multiplication is often denoted by the dot sign,
operation
In mathematics, an operation is a procedure which generates a new value from one or more operands, or mathematical values.
product
The result of multiplying values.
division
Splitting values into equal parts or groups
multiplicative inverse
The multiplicative inverse of a number x is the number you must multiply x by to get 1. For example, 5 and 1/5 are multiplicative inverses.
exponents
Sometimes called a power, it is a quantity that represents repeated multiplication
numbers
A word or symbol (such as ‘five’ or ‘16’) that represents a specific amount or quantity.
expressions
A string of terms that are connected by division, addition, and subtraction operations.
radicand
The number within the radical sign whose square root is to be taken.
data
A set of values of qualitative or quantitative variables; pieces of data are individual pieces of information.
base number
The number multiplied by itself when paired with an exponent. For example, in 8 to the third power, 8 would be the base number.
operators
A word or symbol (such as + or -) that indicates an operation between values.
whole number
A number whose value is 0 or greater (negative numbers are not considered whole numbers) and can be represented without a fractional or a decimal component.
addition
Finding the total of two or more values.
factor tree
A graphical method used to identify the prime factorization of an integer.
estimation
Approximating a value for a calculation
