Answer:
mean = 11.2 = 11
Step-by-step explanation:
mean = average = (10+11+10+12+10+11+13+13+11+11)/10 = 11.2=11
The area is 7.07
A=1/4(pi)d^2
I think the greatest number less than 700 with 9 in the tens place and different digits in each of the other places is 698.
I chose 6 to be in the one of hundreds place because it is the greatest number that is less than 7 in the hundreds place. I also chose 8 to be in the ones place because it is different from 6 and 9 and the greatest number in the ones place that is not 9.
