Answer:170
Step-by-step explanation:
Multiply 210 by 0.70 because that's equal to 70%. This will give you the answer.
B 8x 10 ^-5 is the correct answer
One way to do this is to consider what the average of these integers is. It would be 519/6, or 86.5. This means the six integers are "centered" around 86.5: they would be 84, 85, 86, 87, 88, and 89 (there are three numbers greater than 86.5 and three less than 86.5 in this list).
