Mean = Sum/Count = 359/15 = 23.933...
No. 122 + 162 = 400 = 202 so 12, 16, 20 would be a Pythagorean triple, but 12, 16, 18 would not.
2, 4, 6, 8, 10, 12, 14, 16, 18, 20.4, 8, 12, 16, 20.
2+5+9+12+18+18+20=8484 divided by 7 (the amount of numbers you added) equals 12so your answer is 12.
10, 12, 14, 15, 16, 18, 20
10, 12, 14, 15, 16, 18, 20
Mean (12, 18, 19, 20, 21) = 18
12 + 16 + 18 + 20 + 9 = 75
The mode is 16.
No. 122 + 162 = 400 = 202 so 12, 16, 20 would be a Pythagorean triple, but 12, 16, 18 would not.
