How do you find the variance 415 10 8 33 25 36 66 63 50 64 49 40?

First mean is calculated.Then calculate deviations from the mean.Then the deviations are squared.Then the squared deviations are summed up.Finally this sum is divided by number of items for which the variance is being calculated. For a population, it is by the number of values, in this case 12. If it is a sample, then we divide by one less, which is 11,For these figures, the variance for the population is 11069.24306. If it is a sample, it is 12075.53788 as the result.


List of combinations for 3 wheel lock with digits 0 to 9?

A 3-wheel lock with each wheel having digits from 0 to 9 means each wheel can have 10 possible values (0 through 9). To find the total number of combinations, you calculate: 10 x 10 x 10 = 1000 So, there are 1000 possible combinations. Here's a list of all combinations from 000 to 999: 000, 001, 002, 003, 004, 005, 006, 007, 008, 009, 010, 011, 012, 013, 014, 015, 016, 017, 018, 019, 020, 021, 022, 023, 024, 025, 026, 027, 028, 029,
