Answer:
1/2
Step-by-step explanation:
A die has 6 sides, in which 3 numbers (2 , 4 , 6) are even.
Simplify: 3/6 = 1/2
There is a 1/2 chance that blue is even and green is even.

The standard equation of parabola:
(y-k)²=4p(x-h), with:
a) vertex = (h,k)
b) focus = (h+p, k)
c) directrix = (x=h-p)
Since this parabola has a vertex at (0,0) that means h=k=0
Hence the equation becomes: y²=4px, let's calculate p:
focus is given (-9,0) Remember h+p = -9 & since h=0, then p= -9
===> y²= - 36x
Answer:

Step-by-step explanation:
Answer:
b -17
Step-by-step explanation:
−a^2 − 3b^3 + c^2 + 2b^3 − c^2 =
= -(3²) - 3(2³) + (-3)² + 2(2³) - (-3)²
= -9 - 3(8) + 9 + 2(8) - 9
= -9 - 24 + 9 + 16 - 9
= -17
