The fine print out would be the two ways to another sorry this doesn't make since but i am trying to get some points
To find the IQR you first need to write it in numerical order
77, 81, 83, 84, 86, 86, 88, 92
IQR is just Q3 - Q1
Q1 is the middle of the first have, since it has an even set of 4 numbers in the first half you need to take the average of the two middle ones.. which is 82
Q3 done the same process would be 87.
87 - 82 = 5
IQR = 5
I would say D, determine if it can be factored by grouping (sorry, I forgot to put in the answer here).
Answer:
your answer would be 2 and 1/5 :) hope this helps
