the proper order of operations?
A. 34
B. 49
C. 65
D. 81 - ✔✔B. 49
✔✔Exponents - ✔✔Sometimes called a power, it is a quantity that represents repeated
multiplication.
✔✔Least Common Multiple (LCM) - ✔✔The smallest number in value that is a multiple
of two or more numbers.
✔✔Order of Operations - ✔✔A set of rules that defines the order in which Mathematical
operations should be performed.
✔✔Numerical Summary - ✔✔A number used to describe a specific characteristic about
a data set.
✔✔Joint Frequencies - ✔✔The frequency counts in each cell of the table.
✔✔Linear Extrapolation - ✔✔Estimation using the linear regression equation is made
outside known data points.
✔✔Fair - ✔✔An experiment in which all outcomes are equally likely.
✔✔What is the greatest common factor of 132 and the square root of 121 using prime
factorization?
A. 1
B. 2
C. 10
D. 11 - ✔✔D. 11
, ✔✔Continuous - ✔✔A collection of numbers whose values are not dividable into distinct
values.
✔✔Proper Fraction - ✔✔A fraction where the number in the numerator is less than the
number in the denominator.
✔✔Unlike Terms - ✔✔Terms that do not have the same variable(s) with the same
exponent(s). These terms can not be combined using addition or subtraction.
✔✔Valid Data - ✔✔Data that results from a test that accurately measures what it was
intended to measure.
✔✔Five-Number Summary - ✔✔The minimum, first quartile, median, third quartile, and
the maximum. A box plot represents the five numbers in a five-number summary.
✔✔Observational Study - ✔✔The researcher observes if there is an association
between variables. There is no treatment or control group.
✔✔Conditional Probability - ✔✔A probability that depends on the occurrence of an
earlier event.
✔✔What is the greatest common factor of 24 and 84 using prime factorization?
A. 2
B. 4
C. 8
D. 12 - ✔✔D. 12
✔✔Negative Number - ✔✔A number whose value is less than zero. On the number line,
negative numbers are to the left of zero.
✔✔Numerator - ✔✔The number that is written before the slash, or above the fraction
bar, in a fraction.
✔✔Slope - ✔✔The number that describes the direction and steepness of a line drawn
on the coordinate plane. It is measured by 'rise over run'. Rise/Run = (the change in y
value) / (the change in x value) = (y2-y1)/(x2-x1).
✔✔Statistics - ✔✔The science that deals with the interpretation of numerical facts or
data through theories of probability. Also, the numerical facts or data themselves.
✔✔Conditional Percentages - ✔✔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.
