Step-by-step explanation:
Since we have a vertical directrix, the equation of the parabola is

Where p is the distance from the vertex to the directrix.
or the distance from the vertex to the focus.
Since we have a sideways parabola, let use the point for the directrix is (-6,0). So let find the midpoint of (-6,0) and (6,0). That would be our vertex.


So our vertex is (0,0).
So our equation become

The distance from the focus and directrix is 6.
So p=6.

So p is 6.
Since p is 6,

Factorial is used to find the number of ways a given number of objects can be ordered
Since your second pick is affected by your first pick & your third pick is affected by the first two, it is dependent.
First pick: 18 marbles, 3 are red, so odds are 3/18 = 1/6
Second pick: 17 marbles, 8 are blue, odds are 8/17
Third pick: 16 marbles, 7 are black, odds are 7/16
<span>1/6 * 8/17 * 7/16 = 56/1632 = 7/204 & as mentioned before it's dependent</span>

Using a graphing tool, we can see that the whole range of the function
is <span>y</span><span> ∈ [0,∞)
Now, in the interval

{x | –8 < x < 8}.
The range is
