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
24.85
Step-by-step explanation:
First find the square root of 8.2 and subtract from the square root of 7.5. Multiply 3.5 by 0.71, the answer you get divide it by the answer you get after finding the square root.
1. You want to distribute the equation like this: 8+(2)(x)+(2)(−6)+x—> 8+2x+-12+x.
2. Combine like terms to this equation.
8+2x+-12+x—>(2x+x)+(8+-12)—> 3x+-4
3. You get the answer which is 3x-4.
