Consider the following equation. $xy + 7x + 5x^2 = 3$ (a) Find $dy/dx$ by implicit differentiation. $y' = -10 - \frac{y}{x} - \frac{7}{x}$ (b) Solve the equation explicitly for $y$ and differentiate to get $dy/dx$ in terms of $x$. $y' = \frac{x}{-y + 10x + 7}$ (c) Check that your solutions to parts (a) and (b) are consistent by substituting the expression for $y$ from part (b) into your solution for part (a).

2. Three coins are in a sealed box. One of them is a fair coin (i.e., the probability distribution of the fair coin is shown as P(Head)=0.5 and P(Tail)=0.5. Another one is a two-headed coin and the third coin is a biased toward the head. So, you know that the probability that the third coin comes up head with P(Head)=0.6). When you randomly picked one of three coins and flipped, it showed the head. Compute the probability that it was two-headed coin. (5pts)
