Select the correct answer. Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% ch

GREYUIT [131]

Answer:

Option A 0.1698

Step-by-step explanation:

Given that Jason has a chance for getting oil as 45%

THe kit he buys show accurate result with 80% probability

Let A1- Event that the land has oil

A2 - Event that the land has no oil

B- The test gives negative result

A1 and A2 are mutually exclusive and exhaustive

P(A1) = 0.45 and P(A2) =0.55

Hence we can use Baye theorem

Then P(B) = P(A1B)+P(A2B)= $0.45(0.20)+0.55(0,80)\\=0.09+0.0.44\\=0.53$

Reqd prob =P(A1/B) =

$\frac{P(A1B)}{P(B)}\\ =\frac{0.09}{0.53}\\\\=0.1698$

Solve 9x−y=45 for y.

Taya2010 [7]

So to solve for y, we need to get y alone on one side of the equation. So we are going to subtract 9x from both sides of the equation to get:

$-y=-9x+45$

And since y is negative, we are going to divide both sides by -1 in order to make the y positive:

$y=9x-45$
