Answer:
n=3.8416≅4
So Minimum Sample Size is 4
Step-by-step explanation:
In order to find the minimum sample size, the formula we use will be:
Where:
n is sample size
Z is the distribution
S is the standard deviation
E is the Margin of error
S=3 ,E=3
For Z:
Alpha=1-0.95=0.05
Alpha/2=0.025=2.5%
From Cumulative Standard Distribution Table:
Z at Alpha/2 = 1.960
n=3.8416≅4
So Minimum Sample Size is 4
Answer:
Sophie factored completely.
Carlos did not factor out a 2 out of his last term
Step-by-step explanation:
-4x² − 10x + 6
Sophie factored it as -2(2x − 1)(x + 3) and Carlos factored it as (x + 3)( -4x + 2).
If you look at the last term in Carlos
(x + 3)( -4x + 2)
You can factor out a -2
(x+3) (-2)(2x-1)
It is not factored completely with the negative two inside the parentheses
He could also have factored out a 2
(x+3) (2)(-2x+1)
I like having a positive x so I use the -2
Either would be acceptable.
