The median is defined as... The mathematical center of the distribution.
The point at which the middle value of the distribution falls.
The most frequently occurring score.
The smallest deviation from the mean.

Match each expression with its simplified form.

Use the graph to determine the range. which notations accurately represent the range? check all that apply. (–∞, 2) u (2, ∞) (–∞, –2) u (–2, ∞) {y|y ∈ r, y ≠ –2} {y|y ∈ r, y ≠ 2} y < 2 or y > 2 y < –2 or y > –2

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
