Hans has two route options to drive to work. When he travels Hampton Road, the distribution of times is approximately Normal with a mean of 23.9 minutes and a standard deviation of 3.1 minutes. When Hans

travels Route 8, the distribution of times is approximately Normal with a mean of 20.8 minutes and a standard

deviation of 5.4 minutes. Hans randomly selects 11 times he drove Hampton Road and 11 different times that

he drove Route 8. What is the probability the mean time of the Hampton Road trips will be less than the mean

of the Route 8 trips?

In the triangle abc< angle c is a right angle. find the value of the trig function indicated. find tan a if a =12, b=5 a. 13/12 b. 12/13 c. 5/12 d.12/5

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
