Use the arithmetic series 14 +6+(-2) + (-10) + (-18) + (-26) + (-34) to answer each question. What is the common difference d of the arithmetic
sequence on which the series is based?
d=
DONE
Intro
D=-8
Second question is d

Someone . me. compound probability

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

Complex numbers multiply √-4 * √-25 and show all intermediate steps. alternative notation is sqrt(-4) * sqrt(-25).
