(01.01 lc)which of the following describes a situation in which the total distance a soccer player travels is zero meters from his starting point? the player runs 9 meters forward, and then runs 0 meters in the opposite direction. the player runs 5 meters forward, and then runs 6 meters in the opposite direction. the player runs 10 meters forward, and then runs 10 meters in the opposite direction. the player runs 6 meters forward, and then runs 5 meters in the opposite direction.

Of four points are collinear, they are also coplanar

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.1. (round your answers to four decimal places.) (a) if the distribution is normal, what is the probability that the sample mean hardness for a random sample of 8 pins is at least 51?
