d. Denote the expected return and its standard deviation as functions of π byμ(π ) and σ (π ). The pair (μ(π ), σ (π )) trace out a curve in the plane as πvaries from 0 to 1. Plot this curve. I need to draw a graph from this??
The derivative of ƒ(x) = x2 is zero at x = 0, but ƒ is not a con-stant function. Doesn’t this contradict the corollary of the Mean Value Theorem that says that functions with zero derivatives are constant? Give reasons for your answer.

Vehicle breakdowns are equally likely to occur at any point on a 10 kilometer stretch of a given expressway. An emergency recovery truck is stationed at one end of this stretch of expressway. Assume that the recovery truck travels at a constant speed of 50 kilometers/hour. What is the expected (average) time taken for the recovery truck to reach a vehicle that breaks down on this stretch of expressway?
A sample of 2000 observations has a mean of 74 and a standard deviation of 12. Using Chebyshev’s theorem, find the minimum percentage of the observations that fall in the intervals x +/- 2s, x +/- 2.5s and x +/- 3s Note that x +/- 2s represents the interval x - 2s to x + 2s, and so on Also note that s is symbol for standard deviation in this example
Dave is driving on an American Interstate highway which has a speed limit of 55 mph. At 2 pm he is at milepost 110 and at 5 pm he is at milepost 290. Is this enough evidence to prove that Dave was speeding? Prove using the Mean Value Theorem.
