An ellipse and a hyperbola have the same foci, $a$ and $b$, and intersect at four points. the ellipse has major axis 50, and minor axis 40. the hyperbola has conjugate axis of length 20. let $p$ be a point on both the hyperbola and ellipse. what is $pa \cdot pb$?

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
