STATISTICS REAL EXAM QUESTIONS
AND CORRECT ANSWERS.
rational number - ANSWER -A number that can be written as a ratio of integers, which means it can be
written as a fraction.
- QUESTION- product - ANSWER -The result of multiplying values.
- QUESTION- whole number - ANSWER -A number whose value is 0 or greater and can be represented
without a fractional or a decimal component.
- QUESTION- identity property - 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.
- QUESTION- associative property - 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.
- QUESTION- perfect square - 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,...
- QUESTION- set - ANSWER -In mathematics: a collection of numbers.
- QUESTION- order of operations - ANSWER -A set of rules that defines the order in which mathematical
operations should be performed
- QUESTION- multiplicative inverse - ANSWER -The number you must multiply x by to get 1. For
example, 5 and 1/5.
,- QUESTION- principal square root - ANSWER -The positive square root of a number.
- QUESTION- interval - ANSWER -A set of numbers between two specified values.
- QUESTION- operators - ANSWER -A word or symbol (such as + or -) that indicates an operation
between values.
- QUESTION- commutative - 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.
- QUESTION- radical sign - ANSWER -The symbol which indicates to take the square root of the number
that follows.
- QUESTION- additive inverse - ANSWER -Two numbers equidistant from 0 on a number line whose sum
is 0. For example, 3 and -3.
- QUESTION- greatest common factor (GCF) - ANSWER -The greatest number that is both a factor of a
and a factor of b.
- QUESTION- factor tree - ANSWER -A graphical method used to identify the prime factorization of an
integer.
- QUESTION- integer - ANSWER -A number, (positive, negative, or zero), that can be represented
without a fractional or a decimal component.
- QUESTION- discrete - ANSWER -A collection of numbers whose values are distinct, separate, and
unconnected.
- QUESTION- prime factorization - ANSWER -Determining the set of prime numbers whose product is
the original integer.
, - QUESTION- continuous - ANSWER -A collection of numbers whose values are not dividable into distinct
units.
- QUESTION- expressions - ANSWER -A string of terms that are connected by division, addition, and
subtraction operations.
- QUESTION- quotient - ANSWER -The result of a division expression.
- QUESTION- exponents - ANSWER -Sometimes called a power, it is a quantity that represents repeated
multiplication.
- QUESTION- factor - 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.
- QUESTION- composite number - ANSWER -A number with more factors than just one and itself. Not a
prime number.
- QUESTION- Fundamental Theorem of Arithmetic - 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.
- QUESTION- prime number - ANSWER -A number with only two factors: one and itself.
- QUESTION- percent proportion - ANSWER -Proportion that is equivalent to the given ratio but has a
denominator of 100.
- QUESTION- denominator - ANSWER -The number written after the slash, or below the fraction bar, in
a fraction.
- QUESTION- conditional proportion - ANSWER -A proportion where one part of a proportion is a
variable, or unknown quantity.
