Anew radar device is being considered for a certain missile defense system. the system is checked by experimenting with aircraft in which a kill or a no kill is simulated. two research group a and b participated the simulation, and it was found that 63 kills occur out of 100 trials by group a, and 59 kills occur out of 125 trials by group b. is there a significant difference between the proportions of group a and b's simulation? use p-value with significance level of 0.05 to draw a conclusion.

Two lines parallel to the same plane are parallel to eachother

What is the solution to the equation below? 3/x-2+6=square root x-2 +8

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.
