Item 25 Use a graphing calculator or other technology to answer the question.

Which quadratic regression equation best fits the data set?

yˆ=32.86x2−379.14x+1229.14

yˆ=32.86x2+379.14x−1229.14

yˆ=−1229.14x2−379.14x+32.86

yˆ=32.86x2−379.14x

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.
