Assuming the binomial distribution applies with a sample size of nequals20, find the values below. a. the probability of 5 or more successes if the probability of a success is 0.05 b. the probability of fewer than 4 successes if the probability of a success is 0.20 c. the expected value of the random variable if the probability of success is 0.80 d. the standard deviation of the random variable if the probability of success is 0.80

answer: ouch. thats difficult

step-by-step explanation:

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.  

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
