Using the z-distribution, it is found that the correct option regarding the question in the problem is given by:
B. No, since the confidence interval includes values less than 50%, his opponent may get more votes.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
is the sample proportion.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of 
, so the critical value is z = 1.96.
In this problem, the parameters are given as follows:
Hence, the bounds are given by:
The lower bound is below 0.5, hence option B is correct.

Answer:
C.) 418 cm²
I hope this helped you : )
Step-by-step explanation:
First, you find the area of the square:
19 cm x 19 cm = 361 cm
Next, you find the area of the triangle:
(19 cm x 6 cm) ÷2 =57 cm
Last, you add the two:
361 cm + 57 cm = 418 cm²
Answer:the total trip, and I should be right, was 7 miles. He rowed up for 3 hours, and back for 1.
For this we start by putting km into cm
53.23 x 100,000 = 5,323,000
Now we divide by 53 to see the total number of revolutions
5,323,000 / 53 = 100,433.962 revolutiona
Answer:18 million and 300000
Step-by-step explanation:
Since light travels 180 million KM in 10 min, it would travel 180 million/10 in one minute. Thus, we get 18 million. As we know, there are 60 seconds in a min. Thus, there are 60*10=600 seconds in 10 minutes. Thus, 180 million/600 gives 300000
