defon

Answer:

0.5015 = 50.15% probability that it came from manufacturer A.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

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

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Defective

Event B: From manufacturer A.

Probability a unit is defective:

2% of 43%(from manufacturer A)

1.5% of 57%(from manufacturer B). So

$P(A) = 0.02*0.43 + 0.015*0.57 = 0.01715$

Probability a unit is defective and from manufacturer A:

2% of 43%. So

$P(A \cap B) = 0.02*0.43 = 0.0086$

What is the probability that it came from manufacturer A?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0086}{0.01715} = 0.5015$

0.5015 = 50.15% probability that it came from manufacturer A.

What is the value of y?

RUDIKE [14]

Answer:

C. 55

Step-by-step explanation:

Since all angles in a triangle add up to 180°, we have:

40 + y + y + 30 = 180

2y + 70 = 180

2y = 110

y = 55

4-(2x-3)=3 whats the answer

Oxana [17]

Hello there.

Explanation:

↓↓↓↓↓↓↓↓↓↓

$4-(2x-3)=3$

First, subtract by 4 from both sides.

$4-(2x-3)-4=3-4$

Second, simplify.

$-(2x-3)=-1$

Third, divide by -1 from both sides.

$\frac{-(2x-3)}{-1}=\frac{-1}{-1}$

Fourth, simplify.

$2x-3=1$

Next, add by 3 from both sides.

$2x-3+3=1+3$

Then simplify.

$2x=4$

Therefore, divide by 2 from both sides.

$\frac{2x}{2}=\frac{4}{2}$

Finally, simplify.

$x=2$

<u><em>Answer⇒⇒⇒⇒x=2</em></u>

Hope this helps!
