n is number of moles per unit length and N is number of moles.
n is the sample size.
n-1 means take the sample size and subtract 1 from it.
Population size
n
s=sample standard deviation s=square root (Sum(x-(xbar))2 /(n-1) Computing formula (so you don't have to find the mean and the distance from the mean over and over): square root(Sxx /(n-1)) Sxx= Sum(x2) - ((Sum(x))2/n)
the double of n is m. is the difference between m and n
nothing
n p =n!/(n-r)! r and n c =n!/r!(n-r)! r
n is the sample size.
2n is 2 times n.
what is the difference between 2x and 2n
The difference between s355j2g3 and s355j2 + n is that in the second expression s355j2 is not multiplied by g3. Also in the second expression s355j2 is summed with n.

Suppose the number is N then 4N = 3*abs(35-N) where abs(35-N) is the difference between 35 and N If N > 35 then 4*N = 3*(N-35) = 3*N - 105 So N = -105 If N < 35 then 4*N = 3*(35-N) = 105 - 3*N So 7*N = 105 ie N = 15 So N = -105 or 15
