10 pts 4) A certain function f is differentiable and its derivative is $f'(x) = 10x^2 + 11x - 8$. i) Solve the equation $f'(x) = 0$. The solutions are: ii) Find the general antiderivative of $f'(x) = 10x^2 + 11x - 8$. iii) Derive the explicit formula for $f(x)$, given that $f(3) = 2.5$. Show your work to earn credit. $f(x) =$ iv) List all the intervals over which the function f is increasing: v) List all the intervals over which the function f is decreasing: vi) This function f has a local maximum at a point $x = c$. Calculate $f(c)$. vii) This function f has a local minimum at a point $x = k$. Calculate $f(k)$. viii) Calculate the second derivative of f. $f''(x) =$ ix) Find all the inflection points of f. For full credit, you must also make good a sign chart for $f''$. Give both coordinates for each inflection point.

1. Approximate the probability that in 50 tosses of a fair die, more than 7 sixes will be obtained. Express the probability as a decimal rounded to the nearest thousandth. 2. The weights of the fish in a certain lake are normally distributed with a mean of 8 lb and a standard deviation of 2 lb. If 15 fish are randomly selected, what is the probability that the mean weight will be between 7.0 and 8.2 lb? Express the answer as a percentage rounded to the nearest hundredth without the % sign.
