<span>The weights of the fish in a certain lake are normally distributed with a mean of 18 lb and a standard deviation of 12. </span>
Fifteen-thousand-four-hundred-and-nine.

We know that that the water level is 3 feet below your deck. (-3)
When the tide goes out, the water level lowers 1 foot. (-1)
A storm surge comes in, the water level rises 2 feet. (+2)
New water level: -3-1+2= -4+2= -2
The new water level is 2 feet below the dock.

Rational roots theorem states that any rational root will be a factor of the constant over a factor of the leading coefficient.
The given equation is: <span>f(x) = 3x^4 + x^3 - 13x^2 - 2x + 9. </span>In this case, it is a factor of 9 over a factor of 3.
<span>Factors of 9: ±1, ±3, ±9 </span>
<span>Factors of 3: ±1, ±3 </span>
So possible rational roots are: ±1, ±3, ±9, ±1/3
Answer:
The equation would be:
