I can’t see the answers to any questions. Why?

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

Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.

Need asap. solve for the following inequality
