Last week, 108 cars received parking violations in the main university parking lot. Of these, 27 had unpaid parking tickets from

garik1379 [7]

Answer:

95 percent confidence interval

[0.208,0.29166]

Step-by-step explanation:

First we identificate the sample proportion p = 27 /108, and we find the 95 percent confidence interval for P(population proportion) in this context the parking violations that have prior unpaid parking tickets.

Then α = 0.05 and 1 - α/2 = 0.975

Thus $Z_{0.975} = 1.96$

The 95 percent confidence interval is

[ p ± 1.96 $\sqrt{\frac{p(1-p)}{n} }$ ]

[0.25 ± 1.96 $\sqrt{\frac{0.25*0.75}{108} }$ ]

[0.208,0.29166]

Find the length of arc AD. Use 3.14for r. Round to the nearest tenth.7.9 cmB66.4DС[? ]cmEntar

ch4aika [34]

The first thing we must do is calculate the circumeference:

$\begin{gathered} c=2\cdot\pi\cdot r \\ c=2\cdot3.14\cdot7.9 \\ c=49.612 \end{gathered}$

now, calculate the angle of arc

360° = 49.612

360° - 66.4° - 180° = x

x = 113.6°

now, to calculate the arc length it would be:
