Consider the equation 9 – 4x = 2x.

Which equation resulted from adding 4x to both sides to isolate the variable term?

9 – 2x = 4x
9 = –2x
9 = 6x
4x= 2x – 9

9=6x have a great day

Step-by-step explanation:

9413

Step-by-step explanation:

Given that :

Error = $2 ; Standard deviation (σ) =99 ; α = 95% = 0.95

Zα/2 = Z0. 05/2 = 1.96 (Z probability calculator)...

n = sample size

Recall:

n = ((Zα/2 * σ) / Error)^2

Using the formular above, the sample size n can be obtained ;

n = ((1.96 * 99) / 2)^2

n = 97.02^2

n = 9412.8804

n = 9413
