Question 287942
t = 1/c [ 1n A – 1n(A – N)]
------------------------------------
describe the time, t, in weeks that it takes to achieve mastery of a portion of a task, where A is the maximum learning possible. N is the portion of the learning that is to be achieved, and c is a constant used to measure an individuals learning style. 
a). express the formula so that the expression in brackets is written as a single logarithm 
t = (1/c)[ln[A(A-N)]]
-----------------------------
b). The formula is also used to determine how long it will take chimpanzees to master a task. For example, a typical chimp learning sign language can master a max of 65 signs. se the form of the formula from part (a) to answer this question.
t = (1/c)[ln[A^2-AN]]
---
t = (1/c)[ln[65^2-?]
Note: "N" is missing in your post.
-----------------------------------------
 How many weeks will it take a chimpanzee to master 30 signs if c for that chimp is 0.03?
t = (1/.03)[ln[30^2-30N]]
Note: "N" is missing in your post.
