Answer:

r=5

Step-by-step explanation:

\theta=\frac{2\pi }{3}\\l=\frac{10\pi }{3}\\\theta=\frac{l}{r}\\r=\frac{l}{\theta } \\r=\frac{\frac{10 \pi }{3} }{\frac{2\pi }{3} } \\or~r=\frac{10\pi }{3} *\frac{3}{2\pi } =5

Claim: <em>The mean pulse rate (in beats per minute) of adult males is equal to 68.9 bpm.</em>

<em />

<em>Therefore, the original claim in symbolic form is:</em>

ANSWER:

\mu=68.9\text{ bpm}

Part B. Identify the null and alternative hypotheses.

\begin{gathered} H_0\colon\text{ }\mu=68.9\text{ bpm} \\ H_1\colon\mu\ne68.9\text{ bpm} \end{gathered}\begin{gathered} H_0\text{ or the null hypothesis will be based to our claim. We will test if the mean pulse} \\ \text{rate of an adult male is equal to 68.9 bpm.} \\ H_1\text{ or the alternative hypothesis is the one that contradicts the null hypothesis. That is } \\ \text{why our H}_a\text{ has the sign of not equal to (}\ne). \end{gathered}

find the area of a regular hexagon with an apothem 10.4 yards long and side 12 yards long. Round your answer to the nearest tent
OLga [1]

Answer:

The area of  a regular hexagon with an apothem 10.4 yards long and side 12 yards long is 124.80 yards²

Step-by-step explanation:

Given : A regular hexagon with an apothem 10.4 yards long and side 12 yards long.

We have to find the area of a regular hexagon with an apothem 10.4 yards long and side 12 yards long.  

Since, the Given hexagon is a regular hexagon.

So, each side make equal angle with mid point.

Thus, Area of each triangle = \frac{1}{2} \times base \times height

base = 12 yards

height = 10.4 yards.

Thus, Area of each triangle = \frac{1}{2} \times 12 \times 10.4=62.4

Since, there are 6 triangles.

so area of hexagon = 6 × Area of triangle

area of hexagon = 6 × 62.4 = 124.8 yards²

Thus, The area of  a regular hexagon with an apothem 10.4 yards long and side 12 yards long is 124.80 yards²
