Answer:

1/15

Step-by-step explanation:

there are a total of 10 marbles, of which 3 are pink

therefore the probability of selecting pink on first draw is  3/10

after 1st draw, there are now 9 marbles total and 2 are pink so the probability of selecting pink is 2/9

multiply: 3/10 x 2/9 = 6/90 or 1/15 simplified

Does anyone understand how to do this?
grandymaker [24]

Answer:

<em> f ( x ) = - 2x^2 + 3x + 1</em>

Step-by-step explanation:

If f ( x ) extends to → − ∞, as x→ − ∞ , provided f(x) → − ∞, as x → +∞, we can rewrite this representation as such;

− ∞  < x < ∞, while y > − ∞

Now the simplest representation of this parabola is f ( x ) = - x^2, provided it is a down - facing parabola;

If we are considering a down - facing parabola, the degree of this trinomial we should create should be even, the LCM being negative. Knowing that we can consider this equation;

<em>Solution; f ( x ) = - 2x^2 + 3x + 1</em>, where the degree is 2, the LCM ⇒ - 2
