There are two phases in completing a construction project. The mean time taken to complete Phase I is 16 months, with a standard deviation of 4 months. The mean time taken to complete Phase II is 12 months, with a standard deviation of 3 months. The correlation between the time taken to complete Phase I and Phase II is -0.6, because if Phase I takes a longer time to complete, the construction company tries to rush through Phase II. What is the standard deviation for the total time taken to complete both phases of the project?

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry. how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
