Answer:
Step-by-step explanation:
Given
Required
Determine the probability of selecting two fakes
The probability can be represented as thus:
Using the following probability formula, we have:
Each probability is calculated by dividing number of fakes by total number of gems:
The minus 1 (-1) represent the numbers of fake and total gems left after the first selection
<em>Hence, the required probability is approximately 0.504</em>
The distance formula is , where and are the points.
Substitute in the points.
Subtract.
Solve the exponents.
Add.
Now, we can simplify this square root just a little bit. has a square factor of .
The square root of equals .
x is infinite
x is a function so
if y=f:x
therefore
your answer would be 450
