The probability that an individual without a college education earns more than $50,000 is 0.2, whereas the probability that a person with a B. S. or higher degree earns more than $50,000 is 0.8. The probability that a person chosen at random has a B. S. degree is 0.2. What is the probability that a person has at least a B. S. degree if it is known that he or she earns more than $50,000?

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

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
