The equation whose roots are 3 and 5 is (a) 5 x2 + 8 x + 3 = 0
(c) x2 - 8 x + 15 = 0
(b) 2 x 2 + 8 X – 15 = 0
(d) 3 x 2 + 8 X + 5 = 0

Use the function nest to evaluate p(x) = 1 + x + · · · + x50 at x = 1.00001. (use the matlab ones command to save typing.) find the error of the computation by comparing with the equivalent expression q(x) = (x51 − 1)/(x − 1).

The weight of full–grown tomatoes at a farm is modeled by a normal distribution with a standard deviation of 18.4 grams. the 95 percent confidence interval for the mean weight of the tomatoes is calculated using a sample of 100 tomatoes. what is the margin of error (half the width of the confidence interval)?
