Last year, the enrollment at a local middle school was 865 students. this year the enrollment is 925 students. determine the percent of change and state if it is an increase or decrease. (round your percent to the nearest tenths.)

1. how do you convert the repeating, nonterminating decimal 0. to a fraction? explain the process as you solve the problem.

Compute the standard deviation of the following set of data to the nearest whole number. 10, 10, 15, 20, 25

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.
