If np≥5 and nq≥5, estimate p(fewer than 4) with n=14 and p=0.5 by using the normal distribution as an approximation to the binomial distribution; if np< 5 or nq< 5, then state that the normal approximation is not suitable.

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

regards,  

mrb
