In a study of the accuracy of fast food drive-through orders, one restaurant had 31 orders that were not accurate among 366 orders observed. Use a 0.05 significance level to test the claim that the rate of inaccurate adders is equal to 10% Does the accuracy rate appear to be acceptable?/ identify the null and alternative hypothesis.

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.
