Given the points A(-1, 2) and B(7, 8), determine the coordinates of point P on directed line segment stack A B with bar on top that partitions stack A B with bar on top in a ratio of 1/3.

  P(1, 3.5)

Step-by-step explanation:

Point P is the weighted average of the coordinates of the end points of segment AB. The weights are the reverse of the relative segment lengths.

  P = (3A +1B)/(3+1)

  P = (3(-1, 2) +(7, 8))/4 = (-3+7, 6+8)/4

  P = (1, 3.5)

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
