Discrete data - Answer-Has distinct values, can be counted, had unconnected points
(think dots)
/.Continuous data - Answer-Has values within a range, measured not counted, does not
have gaps between data points (data is connected lines or curves).
/.Example of discrete data - Answer-Days of the week
/.Expressions - Answer-A group of symbols such as numbers and operators that has
mathematical validity
/.Commutative - Answer-The order in which the numbers appear in the sum can be
reversed
/.Identity property - Answer-Adding 0 to any number does not change the original
number
/.Additive inverse - Answer-Values that are equally far from 0 on the number line.
/.Negative - Answer-When multiplying a positive number by a negative number the
result is always
/.Positive - Answer-Multiplying a negative number by a negative number results in a
positive
/.Factors - Answer-Integers that evenly divide the initial integer
/.Prime number - Answer-Positive integer with exactly two positive factors consisting of
1 and itself
/.Composite number - Answer-Has at least one positive factor other than one and itself
/.Factorization - Answer-Process of breaking up a composite number into its prime
factors
, /.fundamental theorem of arithmetic - Answer-Any integer greater than one is either
Prime or the product of Prime numbers
/.Principal square root - Answer-Positive square root of a number
/.Radican - Answer-Number under radical sign √16=4
/.Open Circle - Answer-Represents less than or greatest than on the number line
/.Perfect square - Answer-Product of any integer with itself yields a perfect square.
/.Whole numbers - Answer-positive numbers with a whole value
/.Integers - Answer-Numbers with no fractions or decimal value but can be positive or
negative
/.Rational numbers - Answer-Numbers that can be expressed as a fraction or decimal
values that have that end or repeat forever. Includes all integers since all integers can
be expressed as fractions.
/.Real numbers - Answer-Everything that can be included in a number line including pi.
/.Fractions - Answer-Express numbers which are part of a whole
/.Numerator - Answer-Number written before the slash or above the fraction bar
/.Proper fraction - Answer-Numerator is less than denominator and the value of the
fraction is less than one
/.Improper fraction - Answer-Numerator is greater than denominator and therefore is
greater than one except with negative fractions
/.Mixed numbers - Answer-A whole number and proper fraction. A negative sign in front
applies to both parts of the mixed number.
/.Multiples - Answer-Integers created by multiplying one number times another number
/.Fractions - Answer-Express numbers which are part of a whole
/.Numerator - Answer-Number written before the slash or above the fraction bar
/.Proper fraction - Answer-Numerator is less than denominator and the value of the
fraction is less than one
