Answer:
Option B is the right answer.
Step-by-step explanation:
A parabola is part of a conic section which is got by cutting a right circular cone by a plane, when the intersection gives rise to an open figure.
A parabola is defined as one conic section with eccentricity 1.
Eccentricity is defined as the ratio of distance of the curve from a line to the distance from a point.
In parabola, the line is the directrix, and the point is the vertex.
And always in a parabola, the distance from the directrix will equal the distance from vertex
Hence option b is right.

Step-by-step explanation:
Answer:
1) 1.8
2) 1.7
Step-by-step explanation:
(for part A)
Mean: 3 + 5 + 6 + 3 + 2 + 2 + 1 + 0 + 0 + 4 + 7 + 4 + 5 + 5 + 6 = 53/15 = 3.5
3.5 - 3 = 0.5
3.5 - 5 = 1.5
3.5 - 6 = 2.5
3.5 - 3 = 0.5
3.5 - 2 = 1.5
3.5 - 2 = 1.5
3.5 - 1 = 2.5
3.5 - 0 = 3.5
3.5 - 0 = 3.5
3.5 - 4 = 0.5
3.5 - 7 = 3.5
3.5 - 4 = 0.5
3.5 - 5 = 1.5
3.5 - 5 = 1.5
3.5 - 6 = 2.5
mean absolute deviation: 0.5 + 1.5 + 2.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 0.5 + 3.5 + 0.5 + 1.5 + 1.5 + 2.5 = 27.5/15 = 1.8
(part B)
Mean: -3 + -2 + -1 + 0 + 1 + 2 + 3 = 0/7 = 0
0 - (-3) = 3
0 - (-2) = 2
0 - (-1) = 1
0 - 0 = 0
0 - 1 = 1
0 - 2 = 2
0 - 3 = 3
mean absolute deviation: 3 + 2 + 1 + 0 + 1 + 2 + 3 = 12/7 = 1.7
