Answer:

The correct option is b) no solution.

Step-by-step explanation:

Consider the provided equation,

$x + 2 = x + 4$

We need to find the solution of the above equation.

Subtract x from both the sides as shown.

$x-x+2=x-x+4$

$2=4$

Which is false.

As 2 is not equal to 4.

Hence, the provided equation has no solution.

Thus, the correct option is b) no solution.

At a production process, the produced items are tested for defects. A defective unit is classified as such with probability 0.9,

Snezhnost [94]

Answer:

We use Baye's theorem: P(A)P(B|A) = P(B)P(A|B)

with (A) being defective and

(B) marked as defective

we have to find P(B) = P(A).P(B|A) + P(¬A)P(B|¬A). .......eq(2)

Since P(A) = 0.1 and P(B|A)=0.9,

P(¬A) = 1 - P(A) = 1 - 0.1 = 0.9

and

P(B|A¬) = 1 - P(¬B|¬A) = 1 - 0.85 = 0.15

put these values in eq(2)

P(B) = (0.1 × 0.9) + (0.9 × 0.15)

= 0.225 put this in eq(1) and solve for P(B)

P(B) = 0.4
