a(1) (a). (p. 130)
mutually exclusive events (MYOO-choo-uhl-ee

numbers for one data set decrease as the
numbers for the other data set increase. (p. 228)
negative exponent(NEG-uh-tiv ek-SPOH-nuhnt)
Exponents that are used to express fractions or
decimals that have values between 0 and 1. For
any integer nand any number a, a 0,an.
(p. 88)
