The interior angle measures of a convex pentagon are consecutive multiples of 4. find the measure of each interior angle.

lawyer [7]

Answer:

100°, 104°, 108°, 112°,116°

Step-by-step explanation:

Let the smallest angle be $4x$ . Since, the interior angles are consecutive, the other angles are $4(x+1)$ , $4(x+2)$ , $4(x+3)$ and $4(x+4)$ .

Sum of interior angles = 540°

$4x+4(x+1)+4(x+2)+4(x+3)+4(x+4)=540$ °

$20x+40=540$ °

$20x=(540-40)$ °

$20x=500$ °

$x=(500/20)$ °

$x=25$

Using the value of x to calculate the angles:

$4x=4*25=100$ °

$4(x+1)=4*26=104$ °

$4(x+2)=4*27=108$ °

$4(x+3)=4*28=112$ °

$4(x+4)=4*29=116$ °

In 2015 as part of the General Social Survey, 1289 randomly selected American adults responded to this question:

Radda [10]

Answer:

B (0.312, 0.364)

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence interval $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$

For this problem, we have that:

1289 randomly selected American adults responded to this question. This means that $n = 1289$ .

Of the respondents, 436 replied that America is doing about the right amount. This means that $\pi = \frac{436}{1289} = 0.3382$ .

Determine a 95% confidence interval for the proportion of all the registered voters who will vote for the Republican Party. 

So $\alpha = 0.05$ , z is the value of Z that has a pvalue of $1 - \frac{0.05}{2} = 0.975$ , so $z = 1.96$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3382 - 1.96\sqrt{\frac{0.3382*0.6618}{1289}} = 0.312$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3382 + 1.96\sqrt{\frac{0.3382*0.6618}{1289}} = 0.364$

The 95% confidence interval is:

B (0.312, 0.364)
