How to solve sin^4A-cos^4B=sin^2B-cos^2A

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

40% off the regular price is the correct answer.

step-by-step explanation:

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.

hope this !
