WGU C784 APPLIED HEALTHCARE STATISTICS EXAM QUESTIONS WITH CORRECT ANSWERS LATEST UPDATE A number that can be written as a ratio of integers, which means it can be written as a fraction. - Answers rational number The result of multiplying values. - Answers product A number whose value is 0 or greater and can be represented without a fractional or a decimal component. - Answers 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. - Answers 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. - Answers 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,... - Answers perfect square In mathematics: a collection of numbers. - Answers set A set of rules that defines the order in which mathematical operations should be performed - Answers order of operations The number you must multiply x by to get 1. For example, 5 and 1/5. - Answers multiplicative inverse The positive square root of a number. - Answers principal square root A set of numbers between two specified values. - Answers interval A word or symbol (such as + or -) that indicates an operation between values. - Answers 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. - Answers commutative The symbol which indicates to take the square root of the number that follows. - Answers radical sign Two numbers equidistant from 0 on a number line whose sum is 0. For example, 3 and -3. - Answers additive inverse The greatest number that is both a factor of a and a factor of b. - Answers greatest common factor (GCF) A graphical method used to identify the prime factorization of an integer. - Answers factor tree A number, (positive, negative, or zero), that can be represented without a fractional or a decimal component. - Answers integer A collection of numbers whose values are distinct, separate, and unconnected. - Answers discrete Determining the set of prime numbers whose product is the original integer. - Answers prime factorization A collection of numbers whose values are not dividable into distinct units. - Answers continuous A string of terms that are connected by division, addition, and subtraction operations. - Answers expressions The result of a division expression. - Answers quotient Sometimes called a power, it is a quantity that represents repeated multiplication. - Answers exponents 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. - Answers factor A number with more factors than just one and itself. Not a prime number. - Answers composite number A concept which states that any integer greater than 1 is either prime or is the product of a unique set of prime numbers. - Answers Fundamental Theorem of Arithmetic A number with only two factors: one and itself. - Answers prime number Proportion that is equivalent to the given ratio but has a denominator of 100. - Answers percent proportion The number written after the slash, or below the fraction bar, in a fraction. - Answers denominator A proportion where one part of a proportion is a variable, or unknown quantity. - Answers conditional proportion The number that is written before the slash, or above the fraction bar, in a fraction. - Answers numerator A fraction where the number in the numerator is less than the number in the denominator. - Answers proper fraction Sequence of zeros after the last non-zero digit in a decimal number. - Answers trailing zeros A true statement in which two ratios are equal to each other. - Answers proportion Cross-multiplication method used to determine whether two fractions are equal. The numerator of one fraction is multiplied by the denominator of the opposite fraction on both sides. - Answers butterfly method A method used to change between measurement systems. - Answers unit conversion A decimal number that has a finite number of digits. - Answers terminal decimal The smallest number in value that is a multiple of two or more numbers. - Answers least common multiple (LCM) A method of estimating in order to make working with a number easier. - Answers rounding A reciprocal of a number is that number which, when multiplied by the original number, equals 1. It is the same as the multiplicative inverse. - Answers reciprocal
