Your teacher will assign you to work with either means or medians. 1. A young artist has sold 10 paintings. Calculate the measure of center you were assigned for each of these samples: a. The first two paintings she sold were for $50 and $350.
b. At a gallery show, she sold three paintings for $250, $400, and $1,200. C. Her oil paintings have sold for $410, $400, and $375.
2. Here are the selling prices for all 10 of her paintings: $50, $200, $250, $275, $280, $350, $375, $400, $410, $1200 3. Calculate the measure of center you were assigned for all of the selling prices. 4. Compare your answers with your partner. Were the measures of center for any of the samples close to the same measure of center for the population?​

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
