if part manufacturing data was 10%, 50%, and 90% percentile were 120mm, 150mm, and 180mm. And the lower spec limit were 130mm. What % would we expect to see fall below the lower spec limit?

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
