Probability of heads or tails is .5
so you do (.5)^3 and you get D = 0.125
I believe the answer is -27t - 4
This question is the same as one asking you for the slope of the given function / line. It's immediately apparent from the function that the slope is $15.00/unit.
6 + 7 = 13
20 + 70 = 90
100 + 300 = 400
The 400 + 90 + 13 = 503
