About 30% of adult Internet users are between 18 and 29 years of age. Suppose the probability that a randomly chosen Internet user is in this age group is exactly 0.3. If 15 users are selected at random. (Use the tables or your calculator to analyze a Binomial probability distribution with probability of success of 0.3 and number of trials of 15). What is the probability that at most 10 are between 18 and 29 years?

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.
