The mean of a distribution is the sum of the data elements divided by the count of the dataset.
<em>The mean of the distribution is 4</em>
The complete table is given as
![\left[\begin{array}{cc}People & Frequency &0 - 2 & 5 & 3 - 5 & 25 & 6 - 8 & 5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7DPeople%20%26%20Frequency%20%260%20-%202%20%26%205%20%26%203%20-%205%20%26%2025%20%26%206%20-%208%20%26%205%5Cend%7Barray%7D%5Cright%5D)
The complete question requires that, we calculate the mean of the dataset
First, we calculate the class midpoint
This is the average of the class interval
<u />
<u>For interval 0 - 2, </u>

<u>For interval 3 - 5,</u>

<u>For interval 6 - 8</u>

So, the table becomes
![\left[\begin{array}{ccc}People & x & Frequency &0 - 2 &1 & 5 & 3 - 5 & 4& 25 & 6 - 8& 7 & 5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7DPeople%20%26%20x%20%26%20Frequency%20%260%20-%202%20%261%20%26%205%20%26%203%20-%205%20%26%204%26%2025%20%26%206%20-%208%26%207%20%26%205%5Cend%7Barray%7D%5Cright%5D)
The mean is then calculated as:

This gives



Hence, the mean of the distribution is 4

Answer:
1.23 meters
Step-by-step explanation:
For the first part, the answer is choice B) 360. This applies to any polygon and it doesn't have to be an octagon. The sum of the exterior angles of any polygon is always 360 degrees. This is something you should memorize or have on a reference sheet.
For the second part, the answer is choice C) 142 degrees. We have a parallelogram (specifically a rhombus but that doesn't matter) so the adjacent angles are supplementary. This means they add to 180 degrees. Solving x+38 = 180 leads to x = 142
