Answer:
A) 29/40
Step-by-step explanation:
The formula for this is ...
P(A or B) = P(A) + P(B) - P(A and B)
Filling in the given values, you have ...
P(A or B) = 9/20 +1/2 - 9/40
P(A or B) = 18/40 +20/40 -9/40 = (18+20-9)/40
P(A or B) = 29/40 . . . . matches choice A
Answer:

Step-by-step explanation:
Given the equation

A parabola is the locus of points such that the distance to a point the focus equals the distance to a line the directrix.
is the standard equation for an up-down facing parabola with vertex at (h, k), and a focal length |p|.
so









Parabola is symmetric around the y-axis and so the focus lies a distance\ p from the center (0, 0) along the y-axis.
