Anormal die (numbered 1-6) is fair if each outcome is equally likely. therefore a 1, should come up of the time. if a fair die is rolled 360 times we would expect a 1 to come up 60 times since (1/6*360=60) if x represents the number of times "1" is rolled then\left | (x-60)/\sqrt{50} \right | < 1.95 gives reasonable range for the number of times a "1" will come up in 360 rolles. if we roll the dice 360 times and get "1" 30 times, is our die a fair die? show all work

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
