Answer:
The answer is B ( X>6 )
Step-by-step explanation:
2x+4= 16
2x = 16 - 4
2x = 12
x = 12/2
x= 6
x>6
A;
30 + 8g = c
B;
60 + 3g = c
60 + 3g = 30 + 8 g
30 = 5g
g = 6
6 gigs would have to be used in both for the cost to be the same
(-12x) / (-2)
To solve...-12/-2 or cancel the negatives out and:
12/2= 6
Now just leave
Your answer is D.
D. 6x
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.
