A boy threw a ball 25 times. Kinetic energy of the ball is as follows: 25.66, 30.71, 18.32, 16.77, 24.05, 19.49, 14.22, 20.03, 14.21, 28.43, 28.03, 22.07, 29.48, 14.91, 17.12, 15.12, 27.97, 23.02, 23.37, 27.55, 23.48, 19.90, 15.78, 28.88, 29.71 J. Calculate a point estimate of the proportion of all ball throws whose energy deviation from the mean is larger than the standard deviation. Round your answer to two decimal places (e. g. 98.76).

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.
