Answer:
$9,220,000(0.888)^t
Step-by-step explanation:
Model this using the following formula:
Value = (Present Value)*(1 - rate of decay)^(number of years)
Here, Value after t years = $9,220,000(1 -0.112)^t
Value after t years = $9,220,000(0.888)^t
Answer:

Step-by-step explanation:
Answer:
And we know that each time that we win we recieve $1 and each time we loss we need to pay $1, so then the expected value would be given by:
And the variance is defined as:
Step-by-step explanation:
For this case we know that we can win if we select 2 balls of the same color, so we can find the probability of win like this:
So then the probability of no win would be given by the complement:
We can define the random variable X who represent the amount of money that we can win.
And we can use the definition of expected value given by:
And we know that each time that we win we recieve $1 and each time we loss we need to pay $1, so then the expected value would be given by:
We can calculate the second monet like this:
And the variance is defined as:
