13 9/10 divided by 3 1/2

Arlecino [84]

Answer:

$3 \frac{13}{44}$

Step-by-step explanation:

First let's write our equation

$13 \frac{9}{10} \div 3 \frac{1}{2}$

Now let's make them improper fractions

$\frac{139}{10} \div \frac{7}{2}$

Now since we're dividing we with fractions we do the reciprocal and multiply

$\frac{139}{10} \times \frac{2}{7}$

$\frac{139}{5} \times \frac{1}{7} = \frac{139}{42} = 3 \frac{13}{42}$

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: $(0.7335,\ 0.7865)$

Find the area of an equilateral triangle if a side is 8*sqrt(3) m. Round to the nearest whole number.

gavmur [86]

Hello,

8*√3 is the side.
The height is √((8√3)²-(4√3)²)=√(64*3-16*3)=12

Area of the triangle=8*√3*12/2=48√3≈83
