Answer:
1.5n+9.5m^2
Step-by-step explanation:
7m^2 + 6.5n -4n + 2.5m^2 -n
Combine like terms
6.5n-4n-n+7m^2+2.5m^2
1.5n+9.5m^2
The answer is a decreasing exponential function because the percentage of change is constant. You can obtain this answer by looking at the amount of decrease each time and dividing it by the higher value. If you do this for each step, you'll see that there is a 12% decrease for each year.
Using distribution it would be 3m+7
Answer:
Dummy Coding
Step-by-step explanation:
Dummy Coding is used to observe the effect of one categorical variable on another.
In this case, the first categorical variable is independent (ICV) while the other is dependent (DCV).
The dummy coding system makes use of two numerical values; 0 representing the absence of an effect and 1 representing the presence of that effect.
