Answer:B
Step-by-step explanation:
x=1 f = 10(5.5)(1) = 55
x=2, f = 10(5.5)(2) = 110
110-55 = 55
2-1 =1
55/1 = 55
average rate of change = 55
5) all you have to do is calculate which would be 2.9166...
6) 65.898
6 hours to 1 book is a unit rate because the independent variable (books) is equal to 1.
Hope this helps!
Prior to adding 75, the original data has a mean of 41/6 =6.833 & a median of 8
After adding the 75, the mean becomes 116/7 = 16.571 & the median = 9
So the median increased slightly (from 8 to 9) & the mean increased more quickly (from 6.833 to 16.571)
So it's C :The median increases less than the mean increases.
