Answer:
The expectation for the drilling company is $8,375.
Step-by-step explanation:
We have that the expectation for the drilling company is:
is the income that is expected in relation to natural gas being hit. There is a 1/20 probability that gas is hit. If gas is hit, the income will be $260,000. So
is the income that is expected in relation to oil being hit. There is a 1/40 probability that oil is hit. If oil is hit, the income will be $815,000. So
25,000 is subtracted from the expectation because it is the cost to sink a test well.
So,
The expectation for the drilling company is $8,375.
I think the answer is 220?
A mean is just another word for average. We get the average by adding up all the data number and dividing this sum by the number of data numbers there are.
So that list all added up is 40, and since there are 10 numbers, we divide 40 by 10, which gives us a mean of 4 people per household.
We know the equation will be 3(2)^t, so now we need to find the amount of months it will take.
3(2)^9 = 1536
3(2)^11 = 6144
The correct answer is D.
