The populations of several different regions of a state are shown. Find the mean of the data. region 1: 20,200 region 2: 14,500 region 3: 18,800 region 4: 9,300 region 5: 2,200 A. 13,000 B. 14,500 C. 18,000 D. 65,000

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
