Select the two figures that are similar to the 10 by 4 figure that is shown.

12345 [234]

Answer:

None of the above

Step-by-step explanation:

Since our given figure is 10 by 4, we have an area of 40. The pictures must have a similar area of 40 in order to be similar. Since none of the pictures have an area of 40, we have no pictures that are similar.

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: $(0.7335,\ 0.7865)$

mixer [17]

We substitute m=9 in a=28500-1800m

a = 28500 - 1800(9) = 28500 - 16200 = 12300

Answer: 12,300 feet
