Make ‘y’ the subject of the formula

w = x^2 - 2yz

y = x² - w / 2z (D)

Step-by-step explanation:

w = x² - 2yz

w - x² = - 2yz

multiply both sides by -1

-1(w - x²) = -1 (-2yz)

-w + x² = 2yz

x² - w = 2yz

2yz = x² - w

divide both sides by 2z

y = x² - w / 2z

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.
