The mean of the set of numbers that are given in this situation regarding the population will be 1809.33.
<h3>How to solve the mean</h3>
The mean of the numbers will be:
= (1,585 + 1,690 + 1,735 + 1,935 + 2,021 + 1,890) / 6
= 1809.33
The median of the numbers will be:
= (1735 + 1890) / 2
= 1812.50
Also, from the complete question, the first quartile will be 1690 and the third quartile is 1935.

Answer
Find out the the total length of the walking trail .
To prove
Formula

As given
The trail starts at R(−3, 2) and goes to S(2, 2) and continues to T(2, −5).





RS = 5 units
As given
S(2, 2) and continues to T(2, −5).
Now




ST = 7 units
Therefore
Total length of the trail = RS + ST
= 5 units + 7 units
= 12 units
Therefore the total length of the trail is 12 units.
