Suppose CD←→ is a perpendicular bisector of the AB¯¯¯¯¯ , as shown below. Write a narrative paragraph proving that any point on the perpendicular bisector is equidistant from the endpoints of AB¯¯¯¯¯. Refer to the diagram in the steps of your proof, include the names of the properties used, and generalize your thinking to all points along the bisector.

The number of hours per week that the television is turned on is determined for each family in a sample. the mean of the data is 37 hours and the median is 33.2 hours. twenty-four of the families in the sample turned on the television for 22 hours or less for the week. the 13th percentile of the data is 22 hours. approximately how many families are in the sample? round your answer to the nearest integer.

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126
