Yuliya22 [10]

Answer:

The Domain D = {y ∈ R / y ≠ $\dfrac{b}{2}$ y ≠ 0}

Step-by-step explanation:

Let ,

f(y) = $\dfrac{b^{2} - 4by }{2y^{2} - by }$ - $\dfrac{4y}{b-2y}$

The above function would be defined only when the denominator of anyone or both the terms of the function do not become 0 -

$2y^{2} - by$ ≠ 0 and b - 2y ≠ 0

∴ y(2y - b) ≠ 0 and y ≠ $\dfrac{b}{2}$

Either y ≠ 0 or y ≠ $\dfrac{b}{2}$

∵ The domain of a function consists of only those points where the function is defined -

The Domain D consists of all y ∈ Real numbers such that y ≠ 0 and y ≠ $\dfrac{b}{2}$

Answer:

$\frac{8}{9}$

Step-by-step explanation:

Since there are 432 tickets total and Gabriela bought 48, the chances of Gabriela not winning the grand prize is equal to the chance of any of the tickets she did not buy getting drawn. If she bought 48, then she did not buy 432-48=384 tickets. The chances of any of these being drawn is:

$\frac{384}{432}=\boxed{\frac{8}{9}}$
