The monthly salary of workers in the public works department is $1,500, $3,000, $3,500, $3,500, $4,000, $4,500, $5,000, $6,000, $6,500, $6,500, and $9,000. Explain the impact of the outlier(s) on the measure of central tendency for this data set. There is a minimal increase to the mean because there is a low outlier and a high outlier in the data set. There is a minimal decrease to the mean because there is a low outlier and a high outlier in the data set. There is a large increase to the mean because of the $9,000 outlier. There is a large decrease to the mean because of the $1,500 outlier.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
