Answer:
12^5
Step-by-step explanation:
7+5 = 12
therefore 12^5 is the same as (5+7)^5
The second one..................
Answer: false
Step-by-step explanation: Because there is no direct link between the models obtained from forward and backward selection, hence the option is False.

Answer:
a. The initial value is 5575
b. The decay factor is 0.35 or 35%
Step-by-step explanation:
The decay equation is given as;
y = 5575(0.65)^t
Mathematically, a decay equation can be written in the form;
A = Ir^t
where A is the amount at a time, I
is the initial value and r represents the decay rate
a. So by comparing this with what we have, we can see that the initial value is 5575
b. We want to write the decay factor
We can rewrite the equation as;
y = 5575 (1-0.35)^t
where 0.35 = 35/100 which can be said to be 35%
