Abowl contains 3 red, 8 blue, and 7 black beads. margaret randomly selects 3 beads one after the other without replacement. find the probability of getting a red, blue, and black bead, in that order.

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)

Factor the gcf out of the polynomial 9x^6+6x^4+15x^3

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.
