Answer:
Mean:7.7
Median:8
Mode:8
Range:4
Step-by-step explanation:
mean is the same thing as average so we can do 5+(6x2)+(7x4)+(8x8)+(9x5) witch is 5+12+28+64+45=154 154/20= 7.7
medain is the average of the 2 numbers in the and there are 20 dots between
so since the 2 middle numbers are 8 and (8+8)/2=8 \
mode is the most common and since there are the most 8's out of every number 8 is the mode
range is the biggest minus the smallest since the biggest is 9 and the smallest is 5 9-5=4
