Problem 4

ForLesson 1: Getting to Know You

Each set of data was collected from surveys to answer statistical questions. Select all of the data sets that represent numerical data.

Problem 6

ForLesson 5: Construction Techniques 3: Perpendicular Lines and Angle Bisectors

Jada has this idea for bisecting angle \(ABC\). First she draws a circle with center \(B\) through \(A\). Then she constructs the perpendicular bisector of \(AD\).

<p>Circle with center point B, central angle ABD, DA segment, point C is on BD outside of the circle.</p>

<p>Circle with center point B, central angle ABD, DA segment, diameter drawn through B and the midpoint of DA, point C is on BD outside of the circle.</p>

Does Jada's construction work? Explain your reasoning. You may assume that the perpendicular bisector of line segment \(AD\) is the set of points equidistant from \(A\) and \(D\).
