Manufacture of a certain component requires three different machining operations. Machining time for each operation has a normal distribution, and the three times are independent of one another. The mean values are 30, 15, and 20 min, respectively, and the standard deviations are 1, 2, and 1.6 min, respectively. What is the probability that it takes at most 1 hour of machining time to produce a randomly selected component

He that is measured at 220° is a reflex angle. the opposite angle is obtuse. find the measure of obtuse .

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
