The complete square will be $(x-3)^{2}$ = 3

Step-by-step explanation:

Given,

$2x^{2} -12x+12=0$

or, $x^{2} -6x+6=0$ [ by eliminating 2 from both the sides]

To make it square

$x^{2} -6x+6=0$

or, $x^{2} -2xX3+9-9+6=0$ [ $(a+b)^{2}=a^{2} +2ab+b^{2}$

or, $(x-3)^{2}$ = 9-6

or, $(x-3)^{2}$ = 3

Hence the correct option is B

Answer:

Step-by-step explanation:

Given that a machine produces defective parts with three different probabilities depending on its state of repair.

condition Good order Wearing down Needs main Total

Prob 0.8 0.1 0.1 1

Defective 0.02 0.1 0.3

Joint prob 0.016 0.01 0.03 0.056

a) 0.016

b) total = 0.056

c) If not defective from needs maintenance

Prob for not defective = $0.8*0.98+0.1*0.9+0.1*0.7\\=0.784+0.09+0.07\\=0.944$

From machine that needs maintenance = 0.07

So reqd prob = $\frac{0.07}{0.944} \\=0.0741$
