A singer has 20 pairs of earrings, plus another 5 individual earrings which don’t have a match. One morning she reaches into her drawer without looking and pulls out a random earning. What is the probability that the earring she pulls out is part of a pair of earnings (and thus has a match)? Assume each earring has an equal chance of being pulled out of the drawer. Your answer should be a fraction in lowest terms.

40/45 8/9

Step-by-step explanation:

20 pairs= 40 individual

5 individual= 40+4=45 individual

45 individual and 45 in total=

40 over 45

simplify to make 8/9

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!
