Answer:

a. p`± z₀.₀₂₅\sqrt{ \frac{p`q`}{n}  

b.0.6 ±  1.96 \sqrt \frac{0.6* 0.4}{1000}  

c. { -1.96 ≤  p`± z₀.₀₂₅\sqrt{ \frac{p`q`}{n}     ≥ 1.96} = 0.95  

Step-by-step explanation:

Here the total number of trials is n= 1000

The number of successes is p` = 600/1000 = 0.6. The q` is 1 - p`= 1- 0.6 = 0.4

The degree of confidence is 95 %  therefore z₀.₀₂₅ = 1.96 ( α/2 = 0.025)

a.  The formula used will be

p`± z₀.₀₂₅\sqrt{ \frac{p`q`}{n}       ( z with the base alpha by 2 (α/2 = 0.025))

b. Putting the values

0.6 ±  1.96 \sqrt \frac{0.6* 0.4}{1000}  

c. Confidence Interval in Interval Notation.

{ -1.96 ≤  p`± z₀.₀₂₅\sqrt{ \frac{p`q`}{n}     ≥ 1.96} = 0.95  

{ -z( base alpha by 2) ≤  p`± z₀.₀₂₅\sqrt{ \frac{p`q`}{n}     ≥ z( base alpha by 2)  } = 1- α

Create a binomial with a GCF (Greatest common factor of 6x^3.)
Juli2301 [7.4K]

Answer and Step-by-step explanation:

(2x^{2} )(3x)

I think this would be your answer, since it is a binomial and consists of 3, which is its greatest common factor.

I may be wrong though, so I'm sorry in advance if it is wrong.
