Use the four-step process to find \( f^{\prime}(x) \) and then find \( f^{\prime}(4), f^{\prime}(5) \), and \( f^{\prime}(7) \). \[ \begin{array}{l} f(x)=16 \sqrt{x+6} \\ f^{\prime}(x)=\square \end{array} \]

Nine plants are operated by a garment manufacturer. They feel there is a eighteen percent chance for a strike at any one plant and the risk of a strike at one plant is independent of the risk of a strike at another plant. Let \( X \) be the number of plants of the garment manufacturer that strike. Step 2 of 3 : Compute the expected value of \( X \). Round your answer to two decimal places, if necessary.
