A set consists of all three-digit positive integers with the following properties. Each integer is of the form JKL, where J, K, and L are digits; all the digits are nonzero; and the two-digit integers JK and KL are each divisible by 9. How many integers are in the set?
A campaign director can divide the campaign workers into 10 or 11 teams. When the workers are divided into 11 teams, each of 10 of the teams has x workers and 1 team has 6 workers. When the workers are divided into 10 teams, each of 9 of the teams has x+1 workers and 1 team has 5 workers. How many campaign workers are there?
The standard deviation of $$n$$ numbers $$x_{1}$$, $$x_{2}$$, $$x_{3}$$,......, $$x_{n}$$, with mean $$\overline{x}$$ is equal to $$\sqrt{\frac{s}{n}}$$, where $$S$$ is the sum of the squared differences $$(x_{i} - \overline{x})^{2}$$ for 1 ≤ i ≤ n.

For what value of $$x$$ is the standard deviation of the numbers $$6$$, $$14$$, $$16$$, and $$x$$ least?
