Questions with Answers .
additive inverse - CORRECT ANSWER✅✅Two numbers equidistant from 0 on a
number line whose sum is 0. For example, 3 and -3.
algebraic equation - CORRECT ANSWER✅✅Any equation that contains variables,
constants, or mathematical operations.
algebraic expression - CORRECT ANSWER✅✅A string of terms that are connected by
division, addition, and subtraction operations.
arithmetic expression - CORRECT ANSWER✅✅A string of numbers connected by
elementary operations.
association - CORRECT ANSWER✅✅A pattern or relationship between two variables.
associative property - CORRECT 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.
bar chart - CORRECT ANSWER✅✅A graph that displays data that is distributed over
groups or categories.
bimodal - CORRECT ANSWER✅✅A set of data having two modes.
box plot - CORRECT ANSWER✅✅A graphical rendering of the range and the first and
third quartiles of a data set with the data set's median in the center.
box plots - CORRECT ANSWER✅✅A graphical rendering of the range and the first
and third quartiles of a data set with the data set's median in the center.
butterfly method - CORRECT ANSWER✅✅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.
, categorical data - CORRECT ANSWER✅✅This type of data, also called qualitative
data, consists of data values that can be sorted into groups or categories.
causation - CORRECT ANSWER✅✅A relationship of cause and effect between two or
more variables.
center - CORRECT ANSWER✅✅One of three measures that describe what is "normal"
in a data set: mean, median, or mode.
cluster - CORRECT ANSWER✅✅Several points are grouped together away from the
majority of points in a data set.
coefficients - CORRECT ANSWER✅✅A number by which a variable is multiplied. This
number is written in front of the variable(s).
commutative - CORRECT 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.
complement - CORRECT ANSWER✅✅An event that is the opposite of another event.
composite number - CORRECT ANSWER✅✅A number with more factors than just one
and itself. Not a prime number.
conditional percentages - CORRECT ANSWER✅✅A way to approximate a percentage
by dividing the number of times an event occurred in an experiment by the total number
of respondents in that row or column. See relative frequency.
conditional proportion - CORRECT ANSWER✅✅A proportion where one part of a
proportion is a variable, or unknown quantity.
condtional probability - CORRECT ANSWER✅✅A probability that depends on the
occurrence of an earlier event.
constant - CORRECT ANSWER✅✅A value that is known and unchanging.
contingency table or two-way frequency table - CORRECT ANSWER✅✅A table that
contains frequency counts for two categorical variables.
continuous - CORRECT ANSWER✅✅A collection of numbers whose values are not
dividable into distinct units.
coordinate plane - CORRECT ANSWER✅✅A tool for graphing consisting of a
horizontal x-axis and a vertical y-axis.
