Answer:
6.28 cm
Step-by-step explanation:
Given,
Diameter = 2 cm
pi = 3.14
To find : Circumference ( circle ) = ?
Radius ( r )
= Diameter / 2
= 2 / 2
= 1 cm
Formula : -
Circumference ( circle ) = 2 pi r
2 pi 4
= 2 × 3.14 × 1
= 6.28 cm
11% or 3/9 should be right. Hope it helps :)

Answer:
e. two-sample z-test for two proportions
Step-by-step explanation:
He has two machines, which have a proportion of defective motherboards. He want to compare this two proportions.
He takes two samples, one for each machine, and calculate the proportion in order to statistically test if there are significant difference between the proportions.
Then, this is a two-sample z-test for two proportions
Answer:
Step-by-step explanation:
For rational roots, ,so
We can look at the factors for the constant term and the term multiplying the highest power to see if we can find candidates possible roots.
Factors of 2:
2, 1
Factors of 24:
24, 12, 6, 2, 4, 1, 2, 3, 8
We divide these factors of the constant term by the factors of the term to give us possible factors.
This gives us a set of:
We check all of these roots, by plugging them into the function to see if that will give us a result of 0.
We find the results that give us 0 are:
