Answer:
96
Step-by-step explanation:
3*4*8=96
Well, first in total there are 16 marbles. So the change of getting a black is 7/16. Now we have 15 marbles. The chance is 6/15. Now we have 14 marbles. The chance is 9/14. When you multiply 7/16 x 6/15 x 9/14 = 9/80
Hope this works
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
