Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the land has oil.

Answer:

0.36 = 36% probability that the land has oil and the test predicts it

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.

45% chance that the land has oil.

This means that $P(A) = 0.45$

He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil.

This means that $P(B|A) = 0.8$

What is the probability that the land has oil and the test predicts it?

This is $P(A \cap B)$ . So

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

$P(B \cap A) = P(B|A)*P(A) = 0.8*0.45 = 0.36$

0.36 = 36% probability that the land has oil and the test predicts it

Anyone know where I can get these answers? <br> (There’s also a back but I can’t send it)

Nutka1998 [239]

Answer:

See below

Step-by-step explanation:

<u>Covert equations in standard form into slope-intercept form of y = mx + b</u>

x - y = 3 ⇒ y = x - 3

5x + 3y = 6 ⇒ 3y = -5x + 6 ⇒ y = -5/3x + 2

x - 2y = 2 ⇒ 2y = x - 2 ⇒ y = 1/2x - 1

3x + 2y = -8 ⇒ 2y = -3x - 8 ⇒ y = -3/2x - 4

2x - (-8) - 7x + 4 +10

3241004551 [841]

Answer:

-5x+22

Step-by-step explanation:

we are simplifying

2x-(-8)-7x+4+10=

2x+8+-7+4+10=

2x+8+-7x+4+10

(2x+-7)+(8+4+10)= -5x+22
