Review the graph of . On a coordinate plane, a parabola opens to the right. It goes through (0, 8), has a vertex at (negative 3.5, 2), and goes through (0, negative 4). Everything to the left is shaded.

Which justification can be used to demonstrate the graph is correct?

Boundary values are included as part of the solution set.
The positive coefficient StartFraction 1 Over 10 EndFraction indicates the parabola opens up.
The coefficient of the y2 term is a fraction, so the parabola opens to the right.
Shading is to the left because (0, 0) does not satisfy the inequality.

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
