Answer: The percent that you get your first heads on the 6th toss is about 2.26%.
To reach this event, you would have to flip a tails 5 times in a row. Then, you would have to flip a heads.
If we multiplied all the percent together, it would look like:
0.55 x 0.55 x 0.55 x 0.55 x 0.55 x 0.45
Multiplying those gives a value of 2.26%.
X=-1/8y^2
If the Vertex is at the origin: V=(h,k)=(0,0)→h=0, k=0
y^2=4px
(-8)(x=-1/8y^2)
-8x=y^2
y^2=-8x
4p=-8
Solving for p:
4p/4=-8/4
p=-2<0 (negative)→The parabola opens to the left
Focus: F=(p,0)→F=(-2,0)
Drectrix: x=-p=-(-2)→Directrix: x=2
Answers:
Focus=(-2,0)
Directrix: x=2
