Answer:
Step-by-step explanation:
4 cm × 1000 = 4000 cm = 40 meters
3 cm × 1000 = 3000 cm = 30 meters
A 4 cm by 3 cm section on the map represents 40 m by 30 m.
area = 40 m × 30 m = 1200 m²
Solve for any of the variables; for instance, 
:
Then
Let 
; then the intersection is given by the vector-valued function
or
The set of data can be:
20, 20, 20, 20
Their mean would be:
20 + 20 + 20 + 20 = 80/4 = 20
Hope this helps :)
