everything can be found in the picture
E. None of the above. -16b = 3, divide both sides by -16, b = -3/16
So to find the mean you add them all together and divide by the number of numbers there is so 11+15+19+17+23+20+17+18+21=174 and there are 10 numbers so it would be 174/10 which is 17.4 so you answer is 17.4
