WGU C784 Applied Healthcare Statistics Exam Review (Latest 2024 / 2025 Update) | Questions and Verified Answers | 100% Correct | Grade A Q: In math, you may be asked to "evaluate an expression."--what does that mean? Answer: solve the problem Q: When multiplying a positive number by a negative number, the product will always be Answer: NEGATIVE Q: Multiplying a negative number by a negative number results in a Answer: Positive product (The product of two negatives will always equal a positive.) Q: The result of the division of two negative numbers is always Answer: POSITIVE Q: Zero in multiplication = Answer: The product* of multiplication with zero will always equal zero; whether multiplying by a positive or a negative, any integer multiplied by zero will result in zero as the product. Q: 8(superscript 0) Answer: Any non-zero number with an exponent of 0 (or zero power) equals 1. Q: sampling Answer: The process of selecting research participants from a population Q: exponent Answer: sometimes call a power, it is a number that shows how the baseline number is multiplied by itself Q: probability Answer: the likelihood, or chance, that a certain event will occur Q: Order of operations Answer: A set of rules that tells the order in which to compute. Q: PEMDAS -- order of operations (Please excuse my dear aunt sally) Answer: Parentheses, Exponents & roots, Multiplica- tion, Division, Addition, Subtraction Q: If a problem only contains multiplication and division they are considered equal and you work from left to right (same when the problem only contains addition and subtraction -- work it left to right) Answer: So: 64 divided 2 * 3 = Work it Left to right 64 divided by 2 = 32 x 3 = 96 Q: A ??? is a positive integer with exactly two positive factors*, 11 and itself; it cannot be divided evenly by any other two integers. For example, the only positive numbers that divide 33 are 11 and 33.Therefore, 33 is a prime number. Prime numbers play an important role in factoring, which we will explore later in this module. Answer: prime number Q: prime numbers, only 1 and itself like 29 Answer: It is a prime number. Prime numbers are always odd Q: Composite number Answer: 15--can divide by 1, 3, 5 so it is composite Q: 2, 3, 5, 7 are all what type of numbers Answer: Prime Q: Prime factorization Answer: Breaking down a composite number until all of the
