18.5x=2.59 (18.5 is the total, x is the percent tip, and 2.59 is how much the tip is).
x=.14 (multiply by 100 to get a percentage)
14%
Answer:
W = 0
Y = 20
Step-by-step explanation:
-16.8 = m(4)
-16.8 / 4 = -4.2
So the constant rate is -4.2.

Answer:
With alpha 0.95 and 8 degrees of freedom χ²= 2.73
And with alpha 0.05 and 8 degrees of freedom χ²=15.51
Step-by-step explanation:
The significance level ∝ = 1- 0.9 = 0.1
But we need the area of the middle so we divide this significance level with 2
so that we get exactly the middle area .
Dividing 0.1/2= 0.05
So we will have two values for chi square
One with 0.9 + 0.05 = 0.95 alpha and one with 0.05 alpha . This is because the chi square is right tailed.
So with alpha 0.95 and 8 degrees of freedom χ²= 2.73
And with alpha 0.05 and 8 degrees of freedom χ²=15.51
This can be shown with a graph.
