Simplify brackets
(7w - 2 - w = 2(3w - 1)
simplify 7w - 2 - w to 6w - 2
(6w - 2 = 2(3w - 1)
Expand
(6w - 2 = 6w - 2)
Since both sides are equal, there are infinitely many solutions
Answer: C) INFINITELY MANY
Answer: 12≠6
False
Step-by-step explanation:
Answer:
The expression is 
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the z-score that has a p-value of
.
The margin of error is of:

90% confidence level
So
, z is the value of Z that has a p-value of
, so
.
What expression would give the smallest sample size that will result in a margin of error of no more than 3 percentage points?
We have to find n for which M = 0.03.
We have no prior estimate for the proportion, so we use
. So






The expression is
