Chapter 4.6, Problem 6SP

(a)

To determine

To calculate: The initial score for a student if the model that gives the score after x repetitions of test is:

$P\left(x\right)=\frac{100}{1+19e^{-0.354x}}$.

(b)

To determine

To calculate: The minimum times required for the score to exceed $90$ if the model that gives the score after x repetitions of test is:

$P\left(x\right)=\frac{100}{1+19e^{-0.354x}}$.

(c)

To determine

To calculate: The limiting value of scores if the model that gives the score after x repetitions of test is:

$P\left(x\right)=\frac{100}{1+19e^{-0.354x}}$.
