[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0 <0.3-0.102÷650×12-12×2×10^(-4)×(x^3-15x^2+48x) <0.2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0 <0.3 - 0.102 ÷ 650 × 12 - 12 × 2 × 10 ^ ( -4 ) × ( x ^ 3 - 15 * x ^ 2 + 48 * x )         (1)
        0.3 - 0.102 ÷ 650 × 12 - 12 × 2 × 10 ^ ( -4 ) × ( x ^ 3 - 15 * x ^ 2 + 48 * x ) <0.2         (2)

---

    From inequality(1)：
         x < 11.830119
    From inequality(2)：
         1.42923 < x < √47669989/√7000000 或  x ＞ 10.961173

---

    From inequalities (1) and (2)
         1.42923 < x < √47669989/√7000000 或  10.961173 < x < 11.830119     (3)

---

    The final solution set is :
         1.42923 < x < √47669989/√7000000 或  10.961173 < x < 11.830119
