190.5 / 62 = x / 100

19050 / 62 = 307 if you round

. A factory manufactures widgets using three machines, A, B, and C. Of the total output, machine A is responsible for 30%, machi

Sedaia [141]

Answer:

0.545 = 54.5% probability that it came from machine A

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

$P(B|A) = \frac{P(B)*P(A|B)}{P(A)}$

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Defective.

Event B: Coming from machine A.

Machine A is responsible for 30%

This means that $P(B) = 0.3$

10% of the output from machine A is defective

This means that $P(B|A) = 0.1$

Probability of being defective:

Machine A is responsible for 30%. Of those, 10% are defective.

Machine B is responsible for 20%. Of those, 5% are defective.

Machine C is responsible for 100 - (30+20) = 50%. Of those, 3% are defective. Then

$P(A) = 0.3*0.1 + 0.2*0.05 + 0.5*0.03 = 0.055$

Finally:

$P(B|A) = \frac{P(B)*P(A|B)}{P(A)} = \frac{0.3*0.1}{0.055} = 0.545$

0.545 = 54.5% probability that it came from machine A

Please help, will mark!!

Temka [501]

Answer:

c = 5

Step-by-step explanation:

The Pythagorean theorem states that in every right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the respective lengths of the legs. It is the best-known proposition among those that have their own name in mathematics.

Pythagoras theorem

In every right triangle the square of the hypotenuse is equal to the sum of the squares of the legs.

If in a right triangle there are legs of length a and b the measure of the hypotenuse is c then the following relation is fulfilled:

$a^{2} +b^{2} =c^{2}$

With a = 3 and b = 4

$c=\sqrt{3^{2} +4^{2}} =\sqrt{9+16} =\sqrt{25} \\c=5$
