1. Which of the following best approximates the measure of 2? a. 10
b. 20
c. 30
d. 45​

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

How can you find the mean absolute deviation (mad) for this set of data?
