Group A:
1 dot at 9: 1 x 9 = 9
7 dots at 10: 7 x 10 = 70
8 dots at 15: 8 x 15 = 120
8 dots at 17: 8 x 17 = 136
6 dots at 19: 6 x 19 = 114
Mean: (9+70+120+136+114) / (1+7+8+8+6) = 449/30 = 14.97
Group B:
6 dots at 10: 6 x 10 = 60
5 dots at 14: 5 x 14 = 70
6 dots at 18: 6 x 18 = 108
5 dots at 25: 5 x 25 = 125
4 dots at 28: 4 x 28 = 112
4 dots at 29: 4 x 29 = 116
mean: (60+70+108+125+112+116) / (6+5+6+5+4+4) = 591 / 30 = 19.70

So, we'll find out how much interest this person will have in 6 years and then add it to the original deposit. To do this we will multiply all the factors:
500 x 0.04 x 6 = 120.
This means they'll have made $120 in interest in 6 years if they don't touch the money. We will add the 120 to the 500.
500+120= 620
They will have a total of $620 in their account after 6 years.
10 put the four on top of the zero. and then do 10×10×10×10=10,000 do you get it now any number it says to do power to tens by its just the number of tens u time it by. hope i helped
