You need to find the lowest common multiple which is 6006 :)

Answer from: sabahfayaskhan

The answer is the least common multiple of the number of days each cousin visits.
To find LCM, first find the prime factorization of the two numbers.

42=2*3*7
429=3*11*13

Next, create the prime factorization of the LCM with all of the factors from the original two numbers.
2*3*7*11*13=6006

You don't need to repeat the 3 even though it's in both prime factorizations because each number (of 42 and 429) can still be individually divided out of 6006 one factor at a time. If one of them had the same factor repeated more times than the other (say, your first number had three 3's in its prime factorization and your second number had only one), than you would need to include the greater number of repetitions (in the case of my example, three 3's would need to be in the prime factorization of their LCM).

irst, find the z score of a score of 80. this is given by the formula z = (x-u)/o, where x is the score, u is the mean, and o is the standard deviation. this gives

z = (80-78)/12 = 1/6 = .1667

now, find what percentile a z score of 1/6 correlates to in the normal distribution.

a z score of 1/6 = .1667 is equivalent to the 56.36th percentile of the distribution. so the probability a score is over this is 1-.5636 = .4364

the mean of a sample mean is equal to the original mean. however, the standard deviation of a sample mean is equal to the original standard deviation divided by the square root of n (sample size). so the new standard deviation is 12/sqrt(16) = 3.

the new z score is 80-78/3 = 2/3 = .667. this is equivalent to the 74.86th percentile. so the probability that the mean will be greater than this score is 1-.7486 = .2514.
