Answer:
x is -4/11 or -0.36
Step-by-step explanation:
Answer:
B). As x increases by 1, y increases by 5.
Step-by-step explanation:
When x = 1, y = 5
when x = 2, y = 10
when x = 3, y = 15.
So it is B
As x increases by 1, y increases by 5.
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
