[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1.96*sqrt((1-n/50000)/n*206) <= 9.5*0.1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
        1.96 * sqrt ( ( 1 - n / 50000 ) / n * 206 ) <= 9.5 * 0.1         (1)
        From the definition field of divisor
        x ≠ 0        (2 )
        From the definition field of √
         ( 1 - x / 50000 ) / x * 206 ≥ 0        (3 )

    From inequality(1):
         n ≤ 0
    From inequality(2):
         n < 0 或  n > 0
    From inequality(3):
         n ≥ 0

    From inequalities (1) and (2)
         n < 0    (4)
    From inequalities (3) and (4)
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!    (5)

    The final solution set is :

        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!
