17 and 3 = 20
71
15 + 17 + 19 = 3 x 17 = 51
Sum = 85 Number = 5 So mean = 85/5 = 17
20 & 3
32 + 20 = 4 x (8 + 5)
43
17 and 3 = 20
3 + 17 = 20
It is: 3+17 = 20
3 and 17
7+3=10 17+3=20 17+13=30
the sum would be 1/4 + 3/5 = 5/20 + 12/20 = 17/20
71
15 + 17 + 19 = 3 x 17 = 51
Sum = 85 Number = 5 So mean = 85/5 = 17
Well, honey, if you wanna estimate the sum of 17 and 75, you could round them both to the nearest ten. So, 17 rounds up to 20 and 75 rounds down to 70. Add those together and you get a rough estimate of 90. But hey, who needs estimates when you can just do the math and get the exact sum of 92?
