The value of (51!-50!)/(50!-49!)is........
If x & y are both greater than 0, then
Col A: sqrt (10x) * sqrt (10y)
Col B: 10 * sqrt (xy)
In a distribution of 8500 parameters, if 26.7 is 56 percentile & 37.1 is 78 percentile, then what is the percentile of x (26.7 < =x < =37), that is closest in this range?
A. 1888
B. 4750
C. 6650
& so on....
Given 2 < a < 4 < b < 10, if the average of 3, 6, 9, a, b is 6, then
Col A: a-b
Col B: 4
