The data below represents the scores in a golf tournament. if the mean is 70 with a standard deviation of 4.9, circle all values with a
z-score greater than 0.5

63, 64, 65, 67, 70, 71, 73, 73, 76, 78

70 I think that is the answer

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
