Listed below are altitudes (thousands of feet) and outside air temperatures (°f) recorded during a flight. find the (a) explained variation, (b) unexplained variation, and (c) indicated prediction interval. there is sufficient evidence to support a claim of a linear correlation, so it is reasonable to use the regression equation when making predictions. for the prediction interval, use a 95% confidence level with the altitude of 6327 ft (or 6.327 thousand feet).

Do 12/14 and 8/10 have the same value? explain your answer.

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
