D. 12 truckloads. Because the radius is 6
Answer:
The probability that an Audi A8 car with 2.4L engine is selected given that the car failed emissions test taken within four years of purchase is 0.3589.
Step-by-step explanation:
Let's denote event as follows:
<em>A</em> = an Audi A8 car has a 2.0L engine.
<em>B</em> = an Audi A8 car has a 2.4L engine.
<em>C</em> = an Audi A8 car has a 2.8L engine.
<em>X</em> = an Audi A8 car failed emissions test taken within four years of purchase.
The information provided is:

The probability that an Audi A8 car with 2.4L engine is selected given that the car failed emissions test taken within four years of purchase is:

Compute the probability of an Audi A*8 car failed emissions test taken within four years of purchase as follows:

Compute the value of P (B|X) as follows:

Thus, the probability that an Audi A8 car with 2.4L engine is selected given that the car failed emissions test taken within four years of purchase is 0.3589.
Answer:
100
Step-by-step explanation:
1/2 = 50/x
(cross multiply)
100 = x
The line is going down (from left to right), so it has a negative slope
horizontal lines have zero slope
vertical lines have undefined slope
lines going up (from left to right) would have positive slope
This is going down so it is Choice B
