Hey can someone me with this one too! ?

the answer choices are:

(a) 1067/1825 is a joint relative frequency
(b) 93/1160 is a conditional relative frequency
(c) 93/1160 is a marginal relative frequency
(d) 1160/2027 is a joint relative frequency
(e) 1825/2027 is a conditional relative frequency
(f) 867/2027 is a marginal relative frequency
(g) 1067/2027 is a joint relative frequency

Aregression was run to determine if there is a relationship between hours of tv watched per day (x) and number of situps a person can do (y). the results of the regression were: y=ax+b a=-0.662 b=30.418 r2=0.703921 r=-0.839

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
