Dalton is investigating how long his phone's battery lasts (in hours) for various brightness levels (on a scale of 0-100). His data is displayed in the table and graph below. Do not round between steps. Round answers to 4 decimal places. Brightness | 5 | 55 | 28 | 31| 31| 32| 33| 45| 49 54 Level (x) 57] 6[35][51]41 37 36 2]3.
