Assume there are three machines I, 11, and Ill in a semiconductor manufacturing facility that make chips. They manufacture, respectively, 20, 30, and 50 percent of the total semiconductor chips there. Of their outputs, respectively, 5, 4, and 2 percent of the chips are defective A chip is drawn randomly from the combined output of the three machines
(1) What is the probability that this chip is defective?
(2) Given that this chip is found defective, what is the probability that it was manufactured by machine !? by machine Il? by machine II!?

so what is the question

step-by-step explanation:

what "following statement"?

step-by-step explanation:

it is x equals 3   plese mark me really need it

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
