Product

The result of a multiplication expression

Quotient

The result of a division expression

Discrete Data

Countable, distinct values (number of letters in a word, sales figures)

Continuous Data

A range of values, an infinite number along a spectrum (temperature, height)

A __ is a positive integer with exactly two positive factors, 1 and itself.

Prime number

A __ has at least one positive factor other than 1 and itself.

Composite number

__ is the process of breaking up a composite number into its prime factors.

Factorization

Fundamental Theorem of Arithmetic

A concept that states any integer greater than 1 is either prime or the product of a unique set of prime numbers.

The fact that the sum of a number and 0 will always equal the number is called __.

The identity property

An infinite, repeating decimal is considered a ___ number.

Rational

A __ number is any number on the number line, including zero, negative and positive integers, fractions and decimals.

Real

A decimal whose expansion terminates or repeats is a __ number.

Rational

Which set of numbers is continuous?

Real

A ratio that compares two quantities having different units of measure is a __.

Rate

A __ is a true statement in which two ratios are equal to each other.

Proportion

To convert to Fahrenheit

1.8 x [or x 9/5] Temp in C + 32 = Fahrenheit

To convert to Celcius

(Fahrenheit-32) / 1.8 [or x 9/5] = Celcius temp

Quantitative

The standard deviation rule:

Approx 68% are within 1 SD of mean

Approx 95% are within 2 SD of mean

Approx 99.7% are within 3 SD of mean

What numbers make up the five number summary?

__ is the dataset that appears most in a collection

Mode

The __ is the average of the numbers.

Mean

The __ is the middle number, when arranged in numerical order.

Median

What term is associated with an intersection of events, meaning both must be true

And

The general multiplication rule

P(A and B) = P(A) x P(B|A)

Multiplication rule for independent events

P(A and B) = P(A) x P(B)
