The total amount shared by the friends illustrates mean and average, and the amount spent by each friend is $11.5
<h3>How to determine the amount?</h3>
The given parameters are:
- Total = $76
- Tip = $16
- Number of friends = 8
The amount spent by each friend is calculated using:
Amount = (Total + Tip)/Number of friends
So, we have:
Amount = (76 + 16)/8
Evaluate
Amount = 11.5
Hence, the amount spent by each friend is $11.5

A rule of polygons is that the sum<span> of the </span>exterior angles<span> always equals 360 degrees, but lets prove this for a regular </span>octagon<span> (8-sides). First we must figure out what </span>each<span>of the interior </span>angles<span> equal. To do this we use the </span>formula<span>: ((n-2)*180)/n where n is the number of sides of the polygon</span>

The image of the motion of Paul's derive is attached already.
From the line graph we can obtain a lot of information that will help us unravel the average speed of Paul within the given time frame.
What is average speed?
Average speed is the rate of change of total distance covered with time taken .
Average speed = 
To find the total distance covered;
Distance at time 1 = 75miles
Distance at time 4 = 225miles
Distance covered between 1 - 4 = 225 - 75 = 150miles
Time taken for the journey = 4 - 1 = 3hrs
Input the values in the equation;
Average speed = 
= 50mph

The playground is a square, so there will be a right triangle formed by diagonal and two sides. So sides length²*2=diagonal length². So the side length is 38.9 meter.
