WGU C784 APPLIED HEALTHCARE STATISTICS STUDYGUIDE 2024 LATEST UPDATE
rational number - (correct answer) A number that can be written as a ratio of
integers, which means it can be written as a fraction.
product - (correct answer) The result of multiplying values.
whole number - (correct answer) A number whose value is 0 or greater and can be
represented without a fractional or a decimal component.
identity property - (correct answer) The property that 0 can be added to any number
without changing the value of the number. Likewise, 1 can be multiplied by any number
without changing the value of that number.
associative property - (correct answer) The property 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 both have this
property, but subtraction and division do not.
perfect square - (correct answer) The product of any integer with itself yields this.
So, a number is this if it can be written as the square of an integer. For example, 9 is
this because 3 * 3 = 9. Other examples are 16, 25, 36, 49,...
set - (correct answer) In mathematics: a collection of numbers.
order of operations - (correct answer) A set of rules that defines the order in which
mathematical operations should be performed
multiplicative inverse - (correct answer) The number you must multiply x by to get 1.
For example, 5 and 1/5.
principal square root - (correct answer) The positive square root of a number.
interval - (correct answer) A set of numbers between two specified values.
operators - (correct answer) A word or symbol (such as + or -) that indicates an
operation between values.
commutative - (correct answer) The property that the order of the numbers under
the operation does not change the result. Addition and multiplication have this property:
a + b = b + a and ab = ba.
radical sign - (correct answer) The symbol which indicates to take the square root of
the number that follows.
, additive inverse - (correct answer) Two numbers equidistant from 0 on a number
line whose sum is 0. For example, 3 and -3.
greatest common factor (GCF) - (correct answer) The greatest number that is both a
factor of a and a factor of b.
factor tree - (correct answer) A graphical method used to identify the prime
factorization of an integer.
integer - (correct answer) A number, (positive, negative, or zero), that can be
represented without a fractional or a decimal component.
discrete - (correct answer) A collection of numbers whose values are distinct,
separate, and unconnected.
prime factorization - (correct answer) Determining the set of prime numbers whose
product is the original integer.
continuous - (correct answer) A collection of numbers whose values are not
dividable into distinct units.
expressions - (correct answer) A string of terms that are connected by division,
addition, and subtraction operations.
quotient - (correct answer) The result of a division expression.
exponents - (correct answer) Sometimes called a power, it is a quantity that
represents repeated multiplication.
factor - (correct answer) An integer that divides another integer. We say an integer,
x, is a factor of another integer, y, if the quotient y/x is also equal to an integer.
composite number - (correct answer) A number with more factors than just one and
itself. Not a prime number.
Fundamental Theorem of Arithmetic - (correct answer) A concept which states that
any integer greater than 1 is either prime or is the product of a unique set of prime
numbers.
prime number - (correct answer) A number with only two factors: one and itself.
percent proportion - (correct answer) Proportion that is equivalent to the given ratio
but has a denominator of 100.
