D(A,B) = √5 ≈ 2.2361
A = (2,8)
B = (4,7)
d = distance
-----/\------/\------/\------
sqrt((x2-x1)^2+(y2-y1)^2)
which can be simplified to
sqrt(5)
<span>It doesn't matter that she guessed correctly on the first two questions, guessing the third question correctly is independent of guessing any other question correctly. Therefore, the probability is one out of four, 1/4.</span>
A.) m< E is 31 degrees and the m< F is 43 degrees
B.) m< B is 80 degrees and the m< C is 40 degrees
slope = change in height/change in time
(0,6) (2,3)
= (6-3)/ ((0-2)
= 3/-2
=-3/2
The slope is -3/2
