Write a function search that returns the Tree, whose entry is the given value if it exists and None if it does not. You can assume all entries are unique. def search(t, value): """Searches for and returns the Tree whose entry is equal to value if it exists and None if it does not. Assume unique entries. >>> t = Tree(1, [Tree(3, [Tree(5)]), Tree(7)]) >>> search(t, 10) >>> search(t, 5) Tree(5) >>> search(t, 1) Tree(1, [Tree(3, [Tree(5)]), Tree(7)]) """ "*** YOUR CODE HERE ***"

Think about some of the most memorable and forgettable games ever created. they can be games that were discussed in this unit or otherwise. what are some of the consistent factors that made certain games memorable to you? what were some of the consistent factors that made certain games forgettable to you? why? explain.

Assume that there is a 4% rate of disk drive failure in a year. a. if all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive? b. if copies of all your computer data are stored on three independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?

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.
