4907 divided by 7 = ?
701
The median for the following data set .
1, 1, 1, 1 , 2, 3, 5, 5, 7, 8, 8, 8
There are 12 data points. The mean is between 3-5 so it is 4.
7/8 + 2/8 = ?
1 1/8 or 9/8
Use partitioning and the "box" method to model 82 X 79
True, the answer to both is 4,502
999 X 8 = ?
1000 X 8 - 1 group of 8
8000 - 8 = 7,992
The range of the following data set.
1, 1, 1, 1 , 2, 3, 5, 5, 7, 8, 8, 8
The range is the difference between the maximum and the minimum so 8-1. Range = 7.
