What is the most commonly used measure of variability with measurement data

In the figure shown below, m < 40 and ab =8. which equation could be used to find x?

Gh bisects fgi. find the measure of hgi •15° •21° •10° •8°

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
