Question: The formula t = c 1 [ ln A ln (AN)] describes the time, t, in weeks, that it takes to achieve mastery of a
The formula
t=c1[lnAln(AN)]
describes 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 individual's learning style.
a. Express the formula so that the expression in brackets is written as a single logarithm.
b. Use the form of the formula from part a to answer this question. An animal learning sign language can master a maximum of
60
signs. How many weeks will it take the animal to master
25
signs if the constant c for that animal is
0.02?
a. Express the formula in the brackets as a single logarithm. Choose the correct answer below.
A.
t=1/clnAAN
B.
t=1/clnANA
C.
t=1/cln[A(AN)]
D.
t=1/cln[A(AN)]
b. It will take the animal
weeks to master
25
of
60
signs with
c=0.02.
(Round up to the nearest week.)
