Please help, due soon. Find the length of each arc. Use exact answer
Anna007 [38]

Answer:

C

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × \frac{285}{360}

    = 2π × 18 × \frac{19}{24}

    = 36π × \frac{19}{24} ( cancel 36 and 24 by 12 )

    = 3π × \frac{19}{2}

    = \frac{57\pi }{2} → C

KATRIN_1 [288]

Answer:

The margin of error of his experiment is of 0.1074.

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 level of 1-\alpha, we have the following confidence interval of proportions.

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

In which

z is the z-score that has a p-value of 1 - \frac{\alpha}{2}.

The margin of error is of:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

30 M & M's from a bag, and 3 of them are green.

This means that n = 30, \pi = \frac{3}{30} = 0.1

Standard 95% confidence level

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

Margin of error:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

M = 1.96\sqrt{\frac{0.1*0.9}{30}}

M = 0.1074

The margin of error of his experiment is of 0.1074.
