gary, Heather, and Irene want to find the zeros of the polynomial P(x). They evaluate the polynomial for different values and find: P(−1)=0 P(0)=1 P(2+3–√)=0 Each student interprets this information separately and presents his or her conclusions to the group. Gary concludes that since P(−1) and P(2+3–√) equal 0, 2 zeros of P(x) are −1 and 2+3–√. By the Irrational Root Theorem, 2−3–√ is also a zero of P(x). Heather concludes that since P(0)=1, 1 zero of P(x) is 1. There isn't enough information to determine any other zeros of P(x). Irene concludes that since P(−1) and P(2+3–√) equal 0, 2 zeros of P(x) are −1 and 2+3–√. There isn't enough information to determine any other zeros of P(x). Which statements correctly explain why each student is correct or incorrect?

Me max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
