Discrete data - CORRECT ANSWERS✅✅Has distinct values, can be counted, had
unconnected points (think dots)
Continuous data - CORRECT ANSWERS✅✅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 ANSWERS✅✅Days of the week
Expressions - CORRECT ANSWERS✅✅A group of symbols such as numbers and
operators that has mathematical validity
Commutative - CORRECT ANSWERS✅✅The order in which the numbers appear in the
sum can be reversed
Identity property - CORRECT ANSWERS✅✅Adding 0 to any number does not change the
original number
Additive inverse - CORRECT ANSWERS✅✅Values that are equally far from 0 on the
number line.
Negative - CORRECT ANSWERS✅✅When multiplying a positive number by a negative
number the result is always
Positive - CORRECT ANSWERS✅✅Multiplying a negative number by a negative number
results in a positive
Factors - CORRECT ANSWERS✅✅Integers that evenly divide the initial integer
, Prime number - CORRECT ANSWERS✅✅Positive integer with exactly two positive
factors consisting of 1 and itself

one and itself
