Assume that the richter scale magnitudes of earthquakes are normally distributed with a mean of 1.064 and a standard deviation of 0.571

Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 2

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.

Rounded to the nearest tenth, what is the value of x
