Answer:
Step-by-step explanation:
The fish population after t years can be modeled by the following equation:
In which F(0) is the initial population and r is the constant rate of decay.
Year one the fish population was 18000
This means that 
In year three the fish population was 8000 fish.
Two years later, so 
So
Answer:
slope = -3
y-intercept = -2
Step-by-step explanation:
y = mx + <em>b</em>
m = slope; <em>b</em> = y-intercept
y= -3x <em>- 2</em>
m = -3 = slope
<em>b = -2 = y-intercept</em>
Answer:
Yes
Step-by-step explanation:
According to the empirical rule, roughly 68% of the scores fall between z = -1 and z = 1
You can use a calculator to get a more approximate answer. If you have a TI calculator, you can use the "normalcdf" function to type in normalcdf(-1,1)
Answer:
B
Step-by-step explanation:
x² + y² = 3 creates a circle and circles are not functions because one x-value relates to two y-values instead of one
