Use the table. What inference can you make by comparing the measures of variability? Use the drop down menus to explain your answer.

The (mean, mean absolute deviation) is greater for this year’s 100 meter dash, which suggests that all 30 students (did not improve, improved) equally.

Imogene invested $8,000 in a bank account that pays 8 percent simple interest at the end of each year. her friend invested the same amount in stocks where the growth of the investment is represented as 2,000 times the square root of 2 less than the time lapsed in years. if y1 and y2 represent the amount earned in dollars and t is the time lapsed in years, which system of equations correctly represents the situation?

Suppose y varies directly with x. write a direct variation equation that relates x and y. then find the value of y when x=12 y=7 when x=3

What is the inverse of the function f(x) = 2x + 1?
