In a software engineering process, the productivity of a development team is influenced by the complexity of tasks assigned. The productivity, P (x), in tasks completed per day, is modeled by, P (x ) = 4cos(x ) + 0.5x, where x is a measure of how complex the task is. Find the average productivity of the team from complexity level x = 53 to x = 123. Write only a number as your answer and round to the nearest integer
