If you begin with the basic equation of a vertical parabola:  y-k=a(x-h)^2, where (h,k) is the vertex, then that equation, when the vertex is (-3,-2), is 

y + 2 = a (x + 3)^2.  If we solve this for y, we get

y        = a(x+3)^2 - 2.  Thus, eliminate answers A and D.  That leaves B, since B correctly shows (x+3)^2.

Lucia flips a coin three times. What is the probability she gets (Head, tail, Head) in that order?
Svetach [21]

Answer: \dfrac{1}{8}

Step-by-step explanation:

The total outcomes of tossing a coin = 2

The total number of possible outcomes of flipping coin three times =2 x 2 x 2 = 8

Favorable outcome= (Head, tail, Head) in order

i.e. Number of Favorable outcomes = 1

We know that , Probability = \dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}

Therefore , The required probability =\dfrac{1}{8}

Hence , the probability she gets (Head, tail, Head) in that order=\dfrac{1}{8}
