Age of Senators The average age of senators in the 108th Congress was 63 years. If the standard deviation was 13.5 years, find the z-scores corresponding to the oldest and youngest senators of age 84 and 43. Round z scores to two decimal places. Part: 0 / 20 of 2 Parts Complete The -score corresponding to the oldest senator of age 84 is
.

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
