Answer:
(y - 3)² = 12(x + 3)
Step-by-step explanation:
The focus is to the right of the vertex, so the parabola is sideways and opens to the right.
The conic form of a sideways parabola is
(y - k)² = 4p(x - h)
The vertex is at h = -3; k = 3
The focus is at (h + p, k) = (-3 + p, 3)
The vertex and focus are three units apart, so p = 3.
The equation of your parabola is
(y - 3)² = 12(x + 3)
The figure below shows the graph of your parabola with its focus and vertex.
Answer:
The probability of cured people in who took the remedy is 8/9.
Step-by-step explanation:
Success rate of the cold remedy = 88%
The number of people who took the remedy = 45
Now, 88% of 45 =
and 39.6 ≈ 40
So, out of 45 people, the remedy worked on total 40 people.
Now, let E: Event of people being cured by cold remedy
Favorable outcomes = 40
or, =
Hence, the probability of cured people in who took the remedy is 8/9.
