Discrete data - correct-answer -Has distinct values, can be counted, had
unconnected points (think dots)
Continuous data - correct-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 - correct-answer -Days of the week
Expressions - correct-answer -A group of symbols such as numbers and operators
that has mathematical validity
Commutative - correct-answer -The order in which the numbers appear in the
sum can be reversed
, 2
Identity property - correct-answer -Adding 0 to any number does not change the
original number
Additive inverse - correct-answer -Values that are equally far from 0 on the
number line.
Negative - correct-answer -When multiplying a positive number by a negative
number the result is always
Positive - correct-answer -Multiplying a negative number by a negative number
results in a positive
Factors - correct-answer -Integers that evenly divide the initial integer
Prime number - correct-answer -Positive integer with exactly two positive factors
consisting of 1 and itself
Composite number - correct-answer -Has at least one positive factor other than
one and itself
Factorization - correct-answer -Process of breaking up a composite number into
its prime factors
, 3
fundamental theorem of arithmetic - correct-answer -Any integer greater than
one is either Prime or the product of Prime numbers
Principal square root - correct-answer -Positive square root of a number
Radican - correct-answer -Number under radical sign √16=4
Open Circle - correct-answer -Represents less than or greatest than on the
number line
Perfect square - correct-answer -Product of any integer with itself yields a perfect
square.
Whole numbers - correct-answer -positive numbers with a whole value
Integers - correct-answer -Numbers with no fractions or decimal value but can be
positive or negative
Rational numbers - correct-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.
