Given;
120 deer tagged
800 deer caught
16 out of 800 deer caught have tags
This is a proportion problem
a/b = c/d where ac = bd
16/800 = 120/d
16d = 800*120
16d = 96,000
d = 96,000 / 16
d = 6,000
The estimate number of deer in North Carolina is D. 6,000
Step-by-step explanation:
here it is in pictures

We can factor the equation into:
(x-10)*(x-3)
Therefore the roots are:
X = 10
X = 3
I’m not 100% sure but I think it’s because 20/25 can still be simplified further, while the other 3 can’t.
Answer:
f(x) = 16 * ( 3/4) ^x
Step-by-step explanation:
y = a ( b) ^x
where a is the initial value and b is the growth rate
We know when x =0 y = 16
and when x = 1 y = 12
16 = a * b^0
16 = a * 1
a = 16
So the initial value is 16
12 = 16 * b^ 1
Divide each side by 16
12/16 = b^1
3/4 = b
y = 16 * ( 3/4) ^x
