Let x be the number of people: P(among x, at least two people have same birthday) = 2/x * 1/(x-1) >0.6 2/[(x)x-1] = 0.6 2 / 0.6> x^2 - x x^2 - x > 10/3 3x^2 - 3x - 10 > 0 x > [3+- (3^2-4*3*(-10))^(1/2)] / 2*3 x > (3 + (9+120)^(1/2)) /6 x > 2.39 Therefore x = 3
i think it is if you simlify it the answer would be x+(-2)>8 your welcome aislinn
Factorise into prime numbers and collect the least set of prime numbers: 8 = 2 x 2 x 2 30 = 5 x 3 x 2 Least set is 2 x 2 x 2 x 5 x 3 (miss out the 2 - it appears in both 30 primes and 8 primes) Least common multiple is 2 x 2 x 2 x 5 x 3 = 120
40 = 2 x 2 x 2 x 5 30 = 2 x 3 x 5 Least common denominator = 2 x 2 x 2 x 5 x 3 = 120
12 = 2 x 2 x 3; 40 = 2 x 2 x 2 x 5; 52 = 2 x 2 x 13. The HIGHEST Common Factor is 4; The Least Common MULTIPLE is 1560.
Least common multiple = 7x X 2 = 14x
Find the prime factorization of each: 24 = 2 x 2 x 2 x 3 30 = 2 x 3 x 5 The least common multiple is therefore 2 x 2 x 2 x 3 x 5, or 120.
10 = 10 x 1 40 = 10 x 2 x 2 100 = 10 x 2 x 5 least common multiple = 10 x 2 x 2 x 5 = 200
The least common factor of any set of integers is 1.
The least common multiple of 56 , 64 = 448
240 = 2 x 2 x 2 x 2 x 3 x 5
2 x 2 x 2 x 3 x 5 = 180
2 x 2 x 3 x 3 x 5
