Answer:
x = 1 and y = 4
Step-by-step explanation:
2 * 1 + 2y = 10
2 + 2y = 10
2y = 10-2
2y = 8
y = 4
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, yesterday was 2.90 and today is 2.84, it dropped 6 pennies or $0.06.
now, if we take 2.90 to be the 100%, how much is 0.06 off of it in percentage?
X+(x+1). First Integer is 18. Second Integer is 19

Step-by-step explanation:
Because both seem to have outliers, we want to use IQR instead of standard deviation to determine the spread of data.
