You perform 3 trials of an experiment which produces a new compound. You measure the mass of your product to be 0.05, 0.83, and 1.04 grams. The experiment should have produced 0.76 grams of product. What is your percent error, based on your average measurements? Type your answer as a percentage, rounded to the nearest tenths place.

The change in water level of a lake is modeled by a polynomial function, w(x). described how to find the x-intercepts of w(x) and how to construct a rough graph of w(x) so that the parks department can predict when there will be no chage in the water level. you may create a sample polynomial of degree 3 or higher to use in your explanations.
