Answer:
The sample size required is, <em>n</em> = 502.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population proportion is:
The margin of error is:
Assume that 50% of the people would support this political candidate.
The margin of error is, MOE = 0.05.
The critical value of <em>z</em> for 97.5% confidence level is:
<em>z</em> = 2.24
Compute the sample size as follows:
Thus, the sample size required is, <em>n</em> = 502.
We have been given an equation of hyperbola . We are asked to find the center of hyperbola.
We know that standard equation of a vertical hyperbola is in form , where point (h,k) represents center of hyperbola.
Upon comparing our given equation with standard vertical hyperbola, we can see that the value of h is 6.
To find the value of k, we need to rewrite our equation as:
Now we can see that value of k is . Therefore, the vertex of given hyperbola will be at point
and option D is the correct choice.
