Are you saying the side is 6 inches? ie lenght of the base. i just dont think u have enough data there to work this out?
It would be mean. The mean is the average that is you are looking for, since she wants a summerization of all the values in the data set. To find the mean (average) add all the numbers and then divide by the amount of numbers.
Bruh it's 15. i mean if it is 15/15 then there is 15 things present yunno? idk but i hope this helped, have an amazing day :)
The answer is A!
-4.82, -4(2/3) = - 4.667, sqrt 15 is 3.873, 4.15, 465% is 4.65, and 1.5pi =4.65
Hope this helps!
