experimental probability(ek-sper-uh-MEN-tuhl

will happen based on how often the event occurs
after collecting data from an experiment. (p. 336)
exponent (ek-SPOH-nuhnt) A numeral that tells
you how many times a number, called the base, is
used as a factor. (p. 18)
exponential form(ek-spoh-NEN-shuhl FORM) A
notation used to write an expression in simplified
form using exponents and bases. In 10^3 , 10 is the
base and 3 is the exponent. (p. 18)
exterior angle(ek-STEER-ee-ur ANG-guhl) 1. An
angle formed outside the parallel lines that are
intersected by a transversal. (p. 246) 2. An angle
that is formed outside a polygon and that is
adjacent and supplementary to one of the
polygon’s interior angles. (p. 252)
exterior points(ek-STEER-ee-ur POYNTS) All
points in a plane not part of an angle or its
interior. (p. 242)

product of all positive integers less than or equal
to that integer. (p. 333)
factors(FAK-turz) Numbers that are multiplied to
find a product. The factors of 8 are 1, 2, 4, and 8.
(p. 108)
factor tree(FAK-tur TREE) A visual method for
determining the prime factors of a composite
number. (p. 108)
fair(FAIR) An experiment in which the number of
favorable outcomes is equal to the number of
unfavorable outcomes. (p. 339)
favorable outcomes (FAY-vur-uh-buhl OWT-
kuhms) The outcomes that you are looking for in
an event. (p. 334)
formula(FOR-myuh-luh) An equation, or rule, that
shows a mathematical relationship between two
or more quantities. (p. 46)
frequency (FREE-kwuhn-see) A record of the
number of responses in a survey. (p. 209)
frequency table(FREE-kwuhn-see TAY-buhl) A
method that can be used to organize the data
gathered from surveys in order to show the number
of times each type of answer occurs. (p. 209)

function (FUHNGK-shuhn) A one-to-one relation
in which for each input value, there is only one
output value. (p. 358)
function rule (FUHNGK-shuhn ROOL) A rule
that relates an input (x) value to the
corresponding output (y) value. (p. 359)
function table (FUHNGK-shuhn TAY-buhl) A
table that helps to organize and display thexand
yvalues of a function. (p. 360)
Fundamental Counting Principle(fuhn-duh-
MEN-tuhl KOWNT-ing PRIN-suh-puhl) If an
event can occur inm ways and a second event
can occur in n ways, then the total number of
possible ways that the events can occur together
equalsm •n. (p. 332)
G
geometric constructions (((jee-uh-MET-rik
kuhn-STRUHK-shuhnz) Drawings made with a
compass and a straightedge. (p. 258)
geometric sequence(((jee-uh-MET-rik SEE-
kwuhnss) A sequence of numbers in which each
term is found by multiplying the preceding term
by a fixed number. (p. 353)
greatest common factor (GCF)(GRAYT-ist
KOM-uhn FAK-tur) The greatest number that is
a factor of two or more numbers. (p. 110)
greatest possible error (GPE)(GRAYT-ist
POSS-uh-buhl ER-ur) A term that refers to
one-half of the smallest unit that the measuring
instrument can measure. (p. 272)
H
height of a parallelogram(HITE UHV UH pa-
ruh-LEL-uh-gram) The length of a perpendicular
line segment from the base to the opposite side.
(p. 282)
height of a triangle(HITE UHV UH
TRYE-ang-guhl) The length of a perpendicular line
segment from a base to the opposite vertex. (p. 284)
hemisphere (HEM-iss--feer) Half of a sphere. (p. 303)
histogram(HISS-tuh-gram) A graph that shows
frequencies of data within equal intervals. (p. 218)
hypotenuse (hye-POT-uhn-ooss) The side opposite
the right angle in a right triangle. (p. 280)
I
Identity Property of Addition(eye-DEN-ti-tee
PROP-ur-tee UHV uh-DISH-uhn) Adding 0 and
any number does not change the value of the
number.
a 0 aor 0aa. (p. 14)
