Answer: 0.750
Step-by-step explanation:
Let p be the population proportion .
We are given that a sample of 400 voters reveals that 300 would support her in the November election.
Then the sample proportion for this situation will be :-

Since the sample proportion is the best point estimate for the population proportion.
Therefore, the estimated value of the population proportion =0.750
To find the area of a regular figure,the formula would be:
s^2(n)/4tan (180/n)
where
s is the length of any side
n is the number of sides
In this case:
12^2(6)/4tan (180/6)
=144/4tan(30)
=144/120tan
≈374.1 in^2 (correct to the nearest tenth)
Hope it helps!
