A college administrator wanted to make all freshmen live on campus, because he thought that this would lead to better study habits and better grades. He commissioned a study that found a P‑value less than 0.05 for the difference in GPAs between freshmen who lived on campus and freshmen who commuted. The average GPA for the random sample of freshmen who lived on campus was 2.53, and the average GPA for the random sample of freshmen who commuted was 2.51. When he presented his findings, his idea was rejected. What reason was he most likely given for this rejection?(A) The calculations from the study were likely incorrect.(B) The difference was not practically significant.(C) The difference was not statistically significant.

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
