Lisa swam 6 times as many laps as Amanda. Brynne swam 2 more than six times as many as laps as Amanda. If Lisa and Brynne swam the same amount of laps, how many laps did Amanda swim?

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
