"Increasing" and "decreasing" are references to what the y-values do when the x-values increase.
Attached is a copy of all four tables, marked with whether the y-values increased or decreased on each step (and it also shows how much that increase or decrease was.
The only table that does this is the top right table in the attachment, which is your second table.
What you must do for this case is subtract both quantities and verify the final result.
We have then:
15 3 / 10-13 9/10 =
Rewriting
15.3 - 13.9 =
1.4 =
1 4/10
answer:
this month fell 1 4/10 more centimeters of rain
The term "autonomous" refers to an ordinary differential equation that relates the derivatives of the dependent variable as a function *only* of the dependent variable. In other words, the ODE doesn't explicitly depend on the independent variable.
Examples:

is autonomous

is *not* autonomous
Answer:
using the y intercept formula
Step-by-step explanation:
5, 5, 8, 16, 17, 18
the mode = 5
the median = (8+16)/2 = 24/2 = 12
