<span>x cubed +3x squared - 4x= 0
= x^3 + 3x^2 -4x = 0
=x(x^2 +3x -4) = 0
= x (x+4)(x-1) = 0
x = 0
x+ 4 = 0 then x = -4
x - 1 = 0 then x = 1
answer: x = 0, x = -4 and x = 1</span>

Answer:
Three points may be 2,0;0,1; and 3, -0.5
Answer:
The correct statement are (A) and (F).
Step-by-step explanation:
Events A and B are independent or mutually independent events if the chance of their concurrent happening is equivalent to the multiplication of their distinct probabilities.
That is,
The conditional probability of event <em>A</em> given <em>B</em> is computed using the formula:
And the formula for the conditional probability of event <em>B</em> given <em>A</em> is:
Consider that events <em>A</em> and <em>B</em> are independent.
Then the conditional probability of event <em>A</em> given <em>B</em> will be:
And the conditional probability of event <em>B</em> given <em>A</em> will be:
Thus, the correct statement are (A) and (F).
