Answer:

$n=\frac{0.5(1-0.5)}{(\frac{0.04}{1.64})^2}=420.25$

And rounded up we have that n=421

Step-by-step explanation:

We know that the sample proportion have the following distribution:

$\hat p \sim N(p,\sqrt{\frac{p(1-p)}{n}})$

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by $\alpha=1-0.90=0.1$ and $\alpha/2 =0.05$ . And the critical value would be given by:

$z_{\alpha/2}=-1.64, z_{1-\alpha/2}=1.64$

The margin of error for the proportion interval is given by this formula:

$ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}$ (a)

And on this case we have that $ME =\pm 0.04$ and we are interested in order to find the value of n, if we solve n from equation (a) we got:

$n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}$ (b)

We assume that a prior estimation for p would be $\hat p =0.5$ since we don't have any other info provided. And replacing into equation (b) the values from part a we got:

$n=\frac{0.5(1-0.5)}{(\frac{0.04}{1.64})^2}=420.25$

And rounded up we have that n=421

Answer:

Hexagonal prism

Step-by-step explanation:

Since the base is a hexagon (six sided shape) and there are two of them, it is considered a prism. This is an Hexagonal prism.

Do not confuse it with hexagonal pyramid because:

Answer:

x = - 9

Step-by-step explanation:

In order to find the vertical asymptotes make the denominator equal to zero and solve:

2x + 18 = 0
2x = - 18
x = - 9

There is one vertical asymptote since the denominator is linear expression

Answer:

D) 3 X 10⁷

Step-by-step explanation:

Estimated days:

Jan 2000 to June 2001 = 1.5 years = 365*1.5 days ≈ 548 days

1 day = 24 hours = 24*60 minutes = 24*60*60 seconds =

86400 seconds

548 days = 548 * 86400 seconds =

47347200 ≈ 4.7*10⁷

Best estimate is D) 3 X 10⁷
