The annual production of a business is recorded in the following table. Find the compound annual rate of decline in production for a given period $2017$ - $2020$. (I.e., the average annual coefficient of the production decline, i.e., the ratio that provides a constant decline rate over the time period.) Round the result to four decimal places. $$\begin{array}{|ccccc|}\hline \text{Year}& 2017& 2018& 2019& 2020\\ \text{Production (pcs)}& 55000& 50000& 47000& 45000\\ \hline\end{array}$$
