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. jason decides to test the land for oil. he buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil. what is the probability that the land has oil and the test predicts it? 0.09 0.11 0.36 0.44

C. 0.36

Step-by-step explanation:

We have been given that owners in the area claim that there is a 45% chance that the land has oil. Jason buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil. We are asked to find the probability that the land has oil and the test predicts it.

Since both events are independent, so probability that land has oil and test predicts will be product of probabilities both events.

Therefore, the probability that the land has oil and the test predicts it would be 0.36 and option C is the correct choice.

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
