Vertex form: y = a(x-h)^2 + k

Let's find a.

Substitute vertex and point on parabola into vertex equation:

-1 = a(2-4)^2 - 3

Solve for a:

-1 = a*4 - 3

2 = a*4

a = 1/2

The vertex equation for this parabola is y = 1/2(x-4)^2 - 3

By elimination, the answer is D, y = 1/2(x-4)^2 and y = (1/2)x^2 - 4x + 5

<h3>Answer: D) Not binomial: there are more than two outcomes for each trial. </h3>

Explanation:

Replacement is being done, so each trial is independent. However, the outcomes are values from this set {0,1,2,3,4,5,6,7,8} which represent the number of red marbles chosen. Since we do not have two outcomes, we do not have a binomial distribution. If instead you made the outcomes {red, not red}, then you would have two outcomes and it would be a binomial distribution.
