The equation of parabola is 
Comparing with the vertex form of the parabola: 
Hence, the vertex of the parabola is given by (h,k) = (1, -2)
Now, vertex is the midpoint of the focus and the point on the directrix.
Distance, between vertex and focus is p and that of point on the directrix is p.
Now, let us find p
Thus, the focus is given by
And the directrix is given by
Since, a >0 hence, it is an upward parabola.
The graph is shown in the attached file.
The correct answer is E (6 red, 4 yellow, 8 green, 6 blue, 12 white).
E) 6 + 4 + 8 + 6 + 12 = 36 (total marble count)
6 red/36 total marbles
simplify to find the probability ⬇️
(6/6=1; 36/6=6) = 1/6 chance of picking red
The ball should be aimed to the point of the wall that is about 45 degrees from the wall.
Answer:
1/12
Step-by-step explanation:
There are 12 sides, and 7 is one of them. Therefore, there is a 1/12 chance of it landing on that side if it is a fair cube.
