Suppose that you are given the task of learning​ 100% of a block of knowledge. Human nature is such that we retain only a percentage P of knowledge t weeks after we have learned it. The Ebbinghaus learning model asserts that P is given by ​P(t)=Q+​(100−Q)e−kt​, where Q is the percentage that we would never forget and k is a constant that depends on the knowledge learned. Suppose that Q=35 and k=0.5. Complete parts ​(a) through ​(e) below. ​a) Find the percentage retained after 0​ weeks, 1​ week, 2​ weeks, 6​ weeks, and 10 weeks. Complete the table.
