Write a class named fan to model fans. the properties are speed, on, radius, and color. you need to provide the accessor methods for the properties, and the tostring method for returning a string consisting of all the string values of all the properties in this class. suppose the fan has three fixed speeds. use constants 1, 2, and 3 to denote slow, medium, and fast speeds.
the outline of the class is given as follows:
public class fan {
public final int slow = 1;
public final int medium = 2;

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. the highest speed measured was 78.1 mbps. the complete list of 50 data speeds has a mean of x overbarequals16.11 mbps and a standard deviation of sequals18.65 mbps. a. what is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. how many standard deviations is that [the difference found in part (a)]? c. convert the carrier's highest data speed to a z score. d. if we consider data speeds that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. the difference is nothing mbps.

How do i delete my account on this because i didn't read this agreements and also i put age at xd

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system. currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system. currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system. currenttimemillis() just after the end of the algorithm as the elapsed time.
