Alexxx [7]

Area squares is the side*side, or
$x^{2} =25$
$\sqrt{ x^{2} } = \sqrt{25}$
$x=5$

So, each side equals 5.

A random sample of 1000 registered voters in Flagstaff found 760 registered voters who support immigration reform. Find a 95% co

dusya [7]

Answer: $(0.7335,\ 0.7865)$

Step-by-step explanation:

Given : A random sample of 1000 registered voters in Flagstaff found 760 registered voters who support immigration reform.

sample size : n= 1000

sample proportion: $\hat{p}=\dfrac{760}{1000}=0.76$

Critical value for 95% confidence interval = $z_{\alpha/2}=1.96$

Confidence interval :

$\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.76\pm(1.96)\sqrt{\dfrac{0.76(1-0.76)}{1000}}\\\\=0.76\pm0.0264708866493\\\\\approx0.76\pm0.0265\\\\=(0.76-0.0265,\ 0.76+0.0265)=(0.7335,\ 0.7865)$

Hence, the 95% confidence interval for the true percent of registered voters in Flagstaff who support immigration reform: $(0.7335,\ 0.7865)$

How to complex fractions

I am Lyosha [343]

To do complex fractions, do whats on the bottom and top and then divide the bottom and top fractions and you should get your answer. For example in a equation like 1/2 + 1/2/ 1/4 + 1/4, you would have to solve the equations in the denominator and numerator. So 1/2 + 1/2 is equal to a whole, or 1. So now that we've solved the numerator's equation, the problem is now, 1/1/4 + 1/4. Now I solve for the denominator. 1/4 + 1/4 is equal to 2/4. So now my equation is 1/2/4. Finally I divide 1 by 2/4, which will give me 2. Hope this helps you.
