Let p2 be the vector space of all polynomials of degree 2 or less, and let h be the subspace spanned by 10x2+4x−1, 3x−4x2+3, and 5x2+x−1. the dimension of the subspace h is . is {10x2+4x−1,3x−4x2+3,5x2+x−1} a basis for p2? be sure you can explain and justify your answer. a basis for the subspace h is { }. enter a polynomial or a comma separated list of polynomials.

Cor d? ? 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.
