Bryce is testing whether school is more enjoyable when students are making high grades. he asked 100 students if they enjoyed school and whether their gpa was above or below 3.0. he found that 33 of the 40 students with a gpa above 3.0 reported that they enjoyed school, and 5 of the 60 students with a gpa below 3.0 reported that they enjoyed school. what is the probability that a student with a gpa below 3.0 does not enjoy school?

What is the inverse of the function f(x) = 2x + 1?

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.

Which of these choices show a pair of equivalent expressions?
