A calculator requires a keystroke assembly and a logic circuit. Assume that 83% of the keystroke
assemblies and 88% of the logic circuits are satisfactory.
Assuming that defects in keystroke assemblies are independent of defects in logic circuits,
find the probability that a finished calculator will be satisfactory.

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
