Charles claims he can act as a random number generator. Samantha has doubts. She tells Charles to write down 50 random digits, suspecting that he won't write down 50 random digits, suspecting that Charles produces fewer zeros than the expected 10%? Samantha simulated 100 trails of choosing 50 random digits, assuming that zero has a 1/10 chance of occurring each time. The dotplot shows the number of zeros in each trial. A) Explain how the graph illustrates chance variation. B) Based on the results of the simulation, is there convincing evidence that Charles doesn't choose zero often enough when he's trying to generate random number? Explain.

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy
