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

If f(x)=-4x^2-6x-1 and g(x)=-x^2-5x+3, find (f+g)(x)
Nookie1986 [14]

Answer:

f(x)=-4x^2-6x-1

g(x)=-x^2-5x+3

(f+g)(x) = (-4x^2-6x-1) + (-x^2-5x+3)

-4x^2 - 6x - 1 -x^2 - 5x + 3

= -5x^2 - 11x + 2
