Answer: A. 
Step-by-step explanation:
Given : Jason bought 10 of the 30 raffle tickets for a drawing.
i.e. Total tickets = 30
Also, Number of prizes = 3
The total number of combinations of getting 3 prizes out of 30 tickets = 
The number of combinations of getting 3 prizes out of 10 tickets =
Then, the probability that Jason will win all 3 of the prizes if once a raffle ticket wins a prize it is thrown away will be :
Hence, the probability that Jason will win all 3 of the prizes if once a raffle ticket wins a prize it is thrown away is .
Hence, the correct answer is A. 6/203.

Answer:
The vertex of this parabola is 
Step-by-step explanation:
One way of finding the x-coordinate of the vertex of a parabola is by using the equation 
From the function 
, we can see that
This means that
So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.
Thus, the vertex of this parabola is

Answer:
x = 9
Step-by-step explanation:
2 sides are 4 less than x, that is x - 4
The perimeter is the sum of all 3 sides, thus
x + x - 4 + x - 4 = 19, that is
3x - 8 = 19 ( add 8 to both sides )
3x = 27 ( divide both sides by 3 )
x = 9
