Answer: 3b^3(3b^5+8)
Step-by-step explanation:
They have a 3 in common and both expressions have at least 3 b 's
Answer:
a(n) = 1 + 7(n-1)
Step-by-step explanation:
2/8 and 4/16 are equivalent to 1/4
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.
Answer
40
Explanation
It’s 40 because if you do 20/3 x 2/2 you will get 40/6
