I hope you mean 1/5 when you say 1 5. If that's what you mean, then both, Joshua and Melanie, are correct because, both of their equations are the same.

Joshua's - <span>8 ÷ 1/5 = 40 (Since we can divide a number by fraction, we use this rule: keep, change flip. When we use that Joshua's equation turns into 8 * 5/1 = 8*5 = 40, same as Melanie's.)</span>

If the arc length of a sector in the unit circle is 4.2, what is the measure of the angle of the sector?

iren [92.7K]

Bear in mind the Unit Circle is called so, because its radius is exactly 1, thus just 1 unit, the Unit Circle

anyway $\bf \theta=\cfrac{180s}{\pi r}\qquad 
\begin{cases}
\theta=\textit{central angle in degrees}\\
r=radius\\
s=\textit{length of the arc}\\
----------\\
s=4.2\\
r=1
\end{cases}\implies \theta=\cfrac{180\cdot 4.2}{1\cdot \pi }$

Answer:

C.It is a one-tailed test since the alternative hypothesis states that the parameter is greater than the hypothesized value.

Step-by-step explanation:

Let p be the percentage of students enrolled in an introductory Chemistry class dropped before the midterm. Then null and alternative hypotheses are:

$H_{0}$ : p=10%

$H_{a}$ : p>10%

The alternative hypothesis states that the parameter is greater than the hypothesized value.
