Answer:3.38
Step-by-step explanation:
Count, N: 5
Sum, Σx: 18
Mean, μ: 3.6
Variance, σ2: 11.44
Steps
(10 - 3.6)2 + ... + (2 - 3.6)2
5
=
57.2
5
= 11.44
σ = √11.44
= 3.38
The domain is the x value: (-3)
The range are the y values: (0, 1, 2, 3) in order from least to greatest
No this is not a function because that value of x is "reused". You can "reuse" a y value with different x values but you can't reuse an x value ever, even if the y's are different. x's cannot be the same
If 2 of the vertical angles measure 37, then the other 2 would measure (180 - 37) = 143
3 and 8 are legs of a right triangle. we are looking for the hypotenuse. therefore a²+b²=c²
3²+8²=c²
9+64=c²
73=c²
c=✓73 or about 8.544
