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.
Answer:
Every zero is added to the denominator, you have to add a zero to the decimal too.
Step-by-step explanation:
5/10 = 0.5

Answer:
4x + 15
Step-by-step explanation:
Let the age of Khairul's uncle y.
From the question given above, the following were obtained:
Khairul's age = x years
In 5 years time:
Khairul's age = x + 5
Khairul's uncle age = y + 5
But from the question given above,
Khairul`s uncle will be 4 times as old as what khairul will be in 5 years. This can be written as follow:
y + 5 = 4(x + 5)
Clear bracket
y + 5 = 4x + 20
Subtract 5 from both side
y + 5 – 5 = 4x + 20 – 5
y = 4x + 15
Therefore, Khairul's uncle present age is 4x + 15
