Mean = Sum/Count = 359/15 = 23.933...
To find the mean of the numbers, first sum them up: 18 + 15 + 21 + 10 + 24 + 21 + 18 + 16 + 20 + 22 + 18 + 18 + 12 + 21 + 25 + 20 + 19 + 23 = 346. Then, divide this total by the number of values, which is 18. Thus, the mean is 346 ÷ 18 ≈ 19.22.
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
Mean (12, 18, 19, 20, 21) = 18
To find the mean of the numbers, first sum them up: 18 + 15 + 21 + 10 + 24 + 21 + 18 + 16 + 20 + 22 + 18 + 18 + 12 + 21 + 25 + 20 + 19 + 23 = 346. Then, divide this total by the number of values, which is 18. Thus, the mean is 346 ÷ 18 ≈ 19.22.
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.
