What is the value of N when 49-N equals 24?
25
What is the sum of all the odd numbers from 1 to 49?
The given series is: 1, 3, 5, 7, 9,... 49. The series is an Arithmetic Progression because the difference between any two consecutive terms is 2(a constant). In this A.P. first term(a) = 1, last term(l) = 49 and common difference(d) = 2. nth term of an A.P. is given by an = a + (n-1)d 49 = 1 + (n-1)x2 48 = (n-1)x2 n-1 = 24 n = 25 So there are 25 terms in this A.P. Sum of n terms of an AP is given by: Sn = n/2 x (a + l) S25 = 25/2 x (1 + 49) S25 = 25/2 x 50 S25 = 25 x 25 S25 = 625. So sum of odd numbers from 1 to 49 is 625.

What is 49 over 3 as a percent?

How many 8 numbers combinations can you make from the numbers 1 to 49?
nCr = n!/((n-r)!r!) → 49C8 = 49!/((49-8)!8!) = 49!/(41!8!) = 450,978,066 combinations.
Is 49 a triangular number?
No. ---- The nth triangular number (n must be a whole number > 0) is given by: tn = 1/2 n(n+1) Testing for 49: 1/2 n(n+1) = 49 → n2 + n - 98 = 0 → n = (-1 ± √393)/2 but 393 is not a square number, so n cannot be a whole number which it must be for a triangular number; thus 49 is not a triangular number.
Why is it said that poisson distribution is a limiting case of binomial distribution?
This browser is totally bloody useless for mathematical display but...The probability function of the binomial distribution is P(X = r) = (nCr)*p^r*(1-p)^(n-r) where nCr =n!/[r!(n-r)!]Let n -> infinity while np = L, a constant, so that p = L/nthenP(X = r) = lim as n -> infinity of n*(n-1)*...*(n-k+1)/r! * (L/n)^r * (1 - L/n)^(n-r)= lim as n -> infinity of {n^r - O[(n)^(k-1)]}/r! * (L^r/n^r) * (1 - L/n)^(n-r)= lim as n -> infinity of 1/r! * (L^r) * (1 - L/n)^(n-r) (cancelling out n^r and removing O(n)^(r-1) as being insignificantly smaller than the denominator, n^r)= lim as n -> infinity of (L^r) / r! * (1 - L/n)^(n-r)Now lim n -> infinity of (1 - L/n)^n = e^(-L)and lim n -> infinity of (1 - L/n)^r = lim (1 - 0)^r = 1lim as n -> infinity of (1 - L/n)^(n-r) = e^(-L)So P(X = r) = L^r * e^(-L)/r! which is the probability function of the Poisson distribution with parameter L.

What is the simplest form of n7 over 49?
n7/49 = n/7
If l is greater than m and m is greater than n then what is the relationship between the values of l and n?
If l > m and m > n then l > n by the transitive property of inequality.
