WGU C784 APPLIED HEALTHCARE STATISTICS QUESTIONS AND
ANSWERS A+ GRADED
A number that can be written as a ratio of integers, which means it can be written
as a fraction.
rational number
The result of multiplying values.
product
A number whose value is 0 or greater and can be represented without a fractional
or a decimal component.
whole number
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.
identity property
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.
associative property
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,...
perfect square
In mathematics: a collection of numbers.
set
A set of rules that defines the order in which mathematical operations should be
performed
order of operations
The number you must multiply x by to get 1. For example, 5 and 1/5.
multiplicative inverse
The positive square root of a number.
principal square root
A set of numbers between two specified values.
interval
A word or symbol (such as + or -) that indicates an operation between values.
operators
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.
commutative
The symbol which indicates to take the square root of the number that follows.
radical sign
