Shelly found that the coefficient of determination between the age of a runner x and the runner’s finishing position y was about 0.728. what can she conclude? 72.8% of the variation in and the runner’s finishing position is explained by the runner’s age. 0.728% of the variation in and the runner’s finishing position is explained by the runner’s age. 53% of the variation in and the runner’s finishing position is explained by the runner’s age. 0.728 more variation in and the runner’s finishing position is caused by the runner’s age.

If anyone has done the algebra 2 chaos theory portfolio would you be wiling to me? i kind of know what i'm doing i just don't know if i'm doing it right.

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.
