I offer 4/89 = 4/134,217,728 = 2.98*10-8 approx
Write a randomized algorithm to statistic in a set of n elements Select?
●Analyzing RandomizedSelect()■Worst case: partition always 0:n-1
T(n) = T(n-1) + O(n) = ???
= O(n2) (arithmetic series)
○No better than sorting!
■"Best" case: suppose a 9:1 partition
T(n) = T(9n/10) + O(n) = ???
= O(n) (Master Theorem, case 3)
○Better than sorting!
○What if this had been a 99:1 split?
If using numbers 1 through 5 how man different combinations can be made?
It depends on whether each number is used (a) at most once, (b) exactly once or (c) as many times as you like.
The answers are
(a) 5 + 5*4 + 5*4*3 + 5*4*3*2 + 5*4*3*2*1 = 5+20+60+120+120 = 325
(b) 5*4*3*2*1 = 120
(c) infinite
Is median used for when there is a wide range of numbers?
If the wide range is evenly spread between the very small and the very large (the distribution is symmetric) then there is not much to choose between the median and the mean. If not, the median will have some advantages as a measure of central tendency.
Which coin doesnt have a building on its flip side?
It depends by what you mean building and what type of coin.
Current 2010 US coins don't have buildings on the Penny (it is the union shield), Half Dollar (it is the great seal of the USA), Quarter (it is one of 5 designs of America the Beautiful) or Dime (it is a torch) the only 2010 circulating coin with a building on the back is the nickle. However, older pennies have the Lincoln Memorial on the back. But some of the more recent nickles also don't have buildings on the reverse but rather scenes commemorating Louis and Clark. Plus, bicentennial half dollars have a building on the reverse.

What is described here is the MEAN or AVERAGE, not the quotient.
What is the meaning of properset?
I believe the term "proper set" is not use in math. A "proper subset" is a subset of a given set, that is not equal to the set itself.
When might you want to use a scale or graph that doesnt start at 0?
when you have a chart or graph that starts at a very high number in which case, there is a symbol for that.
How many edges corners and faces does a square based pyrmaid have?
faces: 1 square base + 4 triangular sides = 5 faces
corners: 4 round the square base and one at the top where the sides meet = 5 corners
edges: 4 around the square base and 1 between each of the 4 sides = 8 edges
How many clavers are in a deck of cards?
