The fact is that in order to develop a rational quality control and quality assurance plan (QC/QA), one must formulate technical parameters using statistical methods. Typical uses are for evaluating concrete strength data, soil compaction data or manufacturing processes.
Another key use of mathematics is in the transportation business where a client (say a delivery company) seeks to minimize fuel usage while making all its deliveries on a given day. This is widely-known as the "Traveling Salesman" problem.
Financial institutions manage investment and underwriting risks using statistical methods.
And of course......in the high-tech business and aviation and rocketry.....
The manned variant of the Titan II launch vehicle was plagued by a longitudinal vibration known as "pogo" during its qualification testing in the early 1960s. The problem was solved using advanced mathematical techniques which ultimately resulted in liquid accumulators being installed immediately before the Aerojet engines. Problem solved.
A numerical solution of the RF field equations enabled development of "stealth" technology, a key feature of the Lockheed F-117 Blackhawk.
