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
Answer:
x = 5
Step-by-step explanation:
Using the tangent ratio and the exact value
tan60° = , then
tan60° = = = ( multiply both sides by 5 to clear the fraction )
x = 5
Answer:
i got 6.70820393
Step-by-step explanation:
Some examples are:
1.22
5.51
6.64
-4.11
Basically all you need to do is have 2 of the same digit next to each other.
Using law of cosines:
Cos(angle) = adjacent/ hypotenuse
Cos(22) = 12/x
Rewrite to get:
X = 12/cos(22)
Simplify:
X = 12.9424
Round the answer as needed.
