Evaluate 27x²-42x+12 and the equivalent expression that you wrote in problem 7 for x=2.

Solution:

Given that,

We have to evaluate for x = 2

To evaulate for x = 2, plug in x is equal to 2 in given expression and solve

Substitute x = 2 in given expression

Thus the given expression is evaluated for x = 2 and solution is 36

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.
