Answer:
I=PRT 9.5% in decimal form is .095=11 times rate times tax but we don't know what the tax is.
Find the mean for both:
Sierra: 2 + 11 + 12 + 13 + 15 = 53
53/5 =10.6
Median is the middle value = 12
Alek: 9 + 11 + 11 + 12 + 13 = 56
56/5 = 11.2
Median = 11
A: The medians do not equal the mean.
B: Sierra's are more spread out, ( no identical ages and a greater range ).
C: Sierra's mean is less than Alek.
D. Sierra has an outlier (2).
The answer would be B
Well to find out X, you have to do the opposite to what it's asking to each side. So 11=x-4
+4 onto the 11 and + 4 on to the -4 which means you just have 15=X
