2/3(x)-(-1/3(x)-4)=?
?=0
1÷3 = 0.3
2/3(x) - 0 -1/3(x) = ?
? = 0
2 ÷ 3 =.67
4(3)/ 3
your "x" becomes a negative
So, (-x) - 12 / 3 - 2/3(x)
we get the "12" from multiplying 4(3) from each other
Your like term of this problem▶ -x + 12
2(x) - (-x) - 12 / 3
3(x) + 12
x + 4 = 0
-4 -4
---- ----
4x - 4
4x - 4 = 0
We have one solution to this equation
So, therefore your answer for this question is:
x = -4
Answer:
The minimum number of cities we need to contact is 96.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
Z is the zscore that has a pvalue of 
.
The margin of error is:
95% confidence interval
So 
, z is the value of Z that has a pvalue of 
, so 
.
In this problem, we have that:
The minimum number of cities we need to contact is 96.
