Combinations of r from n without replacement is
c(n,r) = n!/(n-r)!r!
c(n,r) = 23!/20!3!
c(n,r) = 1771.
23 x 22 x 21 x 20/4 x 3 x 2 = 8,855 groups
45
The SOC system identifies 23 major groups of occupations.
The SOC system identifies 23 major groups of occupations.
A LINKAGE GROUP IS FORMED OF ALL THE GENES ON ONE CHROMOSOME. THERE ARE 23 PAIRS OF CHROMOSOMES IN HUMANS. HENCE 23 LINKAGE GROUPS.
If the given dimensions are in feet then 23 times 20 = 460 square feet
There are 5 halves in 10 whole ones.
23
23/20 = 13/20
There are infinitely many groups of 20 numbers that have a mean of 25. One example: 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35
It is 20/23.
Well, it depends on how many groups. It can't be split into whole groups because it is a prime number. But it can be split into 2 groups wit 11.5 in each Hope this helped =)
