In finding this value you average lower and upper bound
(0.6+0.82)/2 = 0.71
=0.71 estimated
margin of error = distance from estimate point lower/ upper bound
This interval will be twice margin error
(0.82-0.6)/2 = 0.11
How far is 0.82 from 0.71 ??
=0.11=11%
2 because you have to draw out a picture if not 5
Scotts method is linear because the number of minutes increased by an equal number every week
⌒DE = 110°
⌒AC = 85° + 25° = 110°
Both arcs have the same measurement; so the chords are the same.
