The management at a plastics factory has found that the maximum number of units a worker can produce in a day is 35. The learning curve for the number N of units produced per day after a newemployee has worked t days is modeled by N35(1 – ekt). After 20 days on the job, a new employee produces 16 units.(a) Find the learning curve for this employee. (Hint: First, find the value of k. Round your value of k to three decimal places.)k =N =(b) How many days does the model predict will pass before this employee is producing 25 units per day? (Round your answer to the nearest whole number.)days

For the following exercises, consider this scenario: The profit of a company decreased steadily overa ten-year spam.The following ordered pairs shows dollars and the number of units sold in hundreds and the profit in thousands ofover the ten-year span, (number of units sold, profit) for specific recorded years: (46,600),(48,550),(50,505),(52,540),(54,495). Use linear regression to determine a function Pwhere the profit in thousands of dollars depends onthe number of units sold in hundreds.
