What dose this = to? triangles = to 180 buts all i know

7. Straight lines are also = to 180°

If you look at the diagram, when you add the two angles together, they form a straight line.

Since the angles add up to 180°, you can do:

(x + 25)° + (4x + 5)° = 180°

x + 25 + 4x + 5 = 180 Combine like terms

5x + 30 = 180 Subtract 30 on both sides

5x = 150 Divide 5 on both sides

x = 30

Half of a set of the parts are manufactured by machine A and half by machine B. Ten percent of all the parts are defective. Six

baherus [9]

Answer:

The probability that a part was manufactured on machine A is 0.3

Step-by-step explanation:

Consider the provided information.

It is given that Half of a set of parts are manufactured by machine A and half by machine B.

P(A)=0.5

Let d represents the probability that part is defective.

Ten percent of all the parts are defective.

P(d) = 0.10

Six percent of the parts manufactured on machine A are defective.

P(d|A)=0.06

Now we need to find the probability that a part was manufactured on machine A, and given that the part is defective :

$P(A|d) =\frac{P(A \cap d)}{P(d)}$

$P(A|d) =\frac{P(d|A)\times P(A)}{P(d)}\\P(A|d)= \frac{0.06\times 0.5}{0.10}$

$P(A|d)= 0.3$

Hence, the probability that a part was manufactured on machine A is 0.3
