Suppose that the weight of navel oranges is normally distributed with mean u and standard deviation a 8 ounces, = 1.5 ounces. determine t such that p(7.53 s x t) i. 0.8. which value characterizes 5% of navel oranges with lowest weight? b. entry to a certain university is determined by a national test. the sco variable random with a mean of 500 and a standard deviation of 100. if a sample of 40 of i. ores on this test are these scores is taken s determine t such that p(x

Nina has prepared the following two-column proof below. she is given that ∠oln ≅ ∠lno and she is trying to prove that ol ≅ on. triangle oln, where angle oln is congruent to angle lno step statement reason 1 ∠oln ≅ ∠lno given 2 draw oe as a perpendicular bisector to ln by construction 3 ∠leo ≅ ∠neo transitive property of equality 4 m∠leo = 90° definition of a perpendicular bisector 5 m∠neo = 90° definition of a perpendicular bisector 6 le ≅ en definition of a perpendicular bisector 7 δole ≅ δone side-angle-side (sas) postulate 8 ol ≅ on cpctc nina made two errors in the proof. identify and correct the errors.
