Mean = 72
First round = 72-3 = 69
Second round = 72-1 = 71
Third round = 76
Explanation:
Total score = 72*3 = 216
69+71+x = 216
140+x = 216
x = 76
Answer:
nearest hundredth 8.944
Step-by-step explanation:
d = √((x2-x1)2 + (y2-y1)2)
Step by step procedure:
Find the difference between coordinates:
(x2-x1) = (-9 - -1) = -8
(y2-y1) = (2 - -2) = 4
Square the results and sum them up:
(-8)2 + (4)2 = 64 + 16 = 80
Now Find the square root and that's your result:
Exact solution: √80 = 4√5
Approximate solution: 8.944
Answer:
0.485
