this is 79.3
then find the distance from every number from the mean
15- 64.3
60- 19.3
90- 10.7
90- 10.7
100- 20.7
100- 20.7
100- 20.7
then find the average of the distances
which is 23.9
hope this helps
Put the numbers in order from smallest to largest:
21,34,45,53,71,88
Since there are an even amount of numbers you must take the middle two and find the average(add them together then divide by 2)
45+53=98
98/2=49
Answer:

Step-by-step explanation:
D. 12 + 13 = 25,
Why you ask? Because the inverse operation of addition is subtraction.
