Suppose that the average and standard deviation of the shelf life in years for certain kinds of batteries are 14.79 and 2.67, respectively. Calculate an interval that is symmetric around the mean such that it contains approximately 68% of battery shelf lives. Assume that the life has a normal distribution.1) (17.46, 12.12)2) (20.13, 9.45)3) (12.12, 17.46)4) (14.79, 2.67)5) (9.45, 20.13)

y = x + 95

y = 42 + 95

y=137 mm hg

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
