Yis inversely proportional to x squared. given that y = 2.5 when x = 24.
1. find an expression for y in terms of x y
2. find the value of y when x=20
3. find the value of x when y=16

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.
