WGU C784 Applied Healthcare Statistics (2026/2027) EXAM QUESTIONS AND ALL CORRECT ANSWERS 100% SOLVED AND GUARANTEED SUCCESS!! rational number A number that can be written as a ratio of integers, which means it can be written as a fraction. product The result of multiplying values. whole number A number whose value is 0 or greater and can be represented without a fractional or a decimal component. identity property 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 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 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 In mathematics: a collection of numbers. order of operations A set of rules that defines the order in which mathematical operations should be performed multiplicative inverse The number you must multiply x by to get 1. For example, 5 and 1/5. principal square root The positive square root of a number. interval A set of numbers between two specified values. operators A word or symbol (such as + or -) that indicates an operation between values. commutative 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 The symbol which indicates to take the square root of the number that follows.
