3) At a school several teachers were holding a contest to see which class could earn the most trivia points. Mrs. Clawson's class scored 94 points. Mr. Grant's class earned 82 points. Mrs. Jones's class earned 94 and Mrs. Price's class earned 86. Determine the mean (rounded to the nearest tenth), median, mode and range of the number of points scored. Mean: Median: Mode: Range:

Mean: 89

Median: 90

Mode: 94

Range: 12

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
