Answer:
0.071 to 0.129
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 
.
For this problem, we have that:
In a sample of 400 voters, 360 indicated they favor the incumbent governor. This means that 400-360 = 40 do not favor the incumbent governor. So 
95% confidence interval
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The correct answer is:
0.071 to 0.129

Answer: 7/2 yards by 10 yards
Step-by-step explanation:
If you work 42 hours per week, before taxes are taken out you will make $882.00 per week. You will make a total of $1764.00 every two weeks. If your only working 42 hours every two weeks you will make $441.00 per week.
Answer:
y = 5x - 11
Step-by-step explanation:
The equation is y = mx+b where m is the slope and b is the y intercept
y = 5x + b (now lets substitute the coordinate in to solve for b)
4 = 5(3) + b
4 = 15 +b
b = -11
y = 5x - 11
