"a bicyclist rides 20 km each way to campus. assume that a gps signal detects her location on the bike path every 20 meters (0.02 km), that is, 1000 data points are collected from start to finish. if the bike path is 2 meters wide, and her target is the center of the bike path, and if her standard deviation is 0. meters, roughly how many of the 1000 gps data points will indicate that she is off of the bike path?

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
