When particle motion of a medium is parallel to the direction of a wave propagation, what is the wave being transmitted called?

____________ utilizes numerical and graphical methods to look for patterns in a data set, to summarize the information revealed in a data set, and to present that information in a meaningful way.

A beacon transmits a signal every 10 minutes (such as 8:20, 8:30, etc.). The time at which a receiver is tuned to detect the beacon is a continuous uniform distribution from 8:00 a.m. to 9:00 a.m. Consider the waiting time until the next signal from the beacon is received. What is the probability that the waiting time is less than 4 minutes?
