Answer:
≈ 82 feet
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to calculate distance (d)
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
Here the hypotenuse is the distance (d) between the 2 poles, hence
d² = 80² + 45² = 6400 + 2025 = 8425 ( take the square root of both sides )
d =
≈ 82 feet ( to the nearest foot )
Answer:
They have 6 when multiplying it
Step-by-step explanation:
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

In which
P(B|A) is the probability of event B happening, given that A happened.
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 
He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil.
This means that 
What is the probability that the land has oil and the test predicts it?
This is
. So


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