The box plots below show student grades on the most recent exam compared to overall grades in the class: Which of the following best describes the information about the medians? (1 point)

a
The exam outlier at 60 makes the IQR narrower and the median higher.

b
The class data is more evenly spread, which pulls its median down.

c
The class median is lower than the exam median.

d
The class Q3 is higher than the exam Q3.

I know alot of people have gotten this wrong and the answer is not The class Q3 is higher than the exam Q3. If you can help me you will also be helping others who need the answer to this question so this will greatly be appreciated.

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)
