The mathematical model for learning an assembly-line procedure needed for assembling one component of a manufactured item is n=−5ln(0.95P−1) where P is the proportion of correctly assembled components after n practice sessions. Solve the equation for P to find an equation for the proportion of correctly assembled components in terms of the number of practice sessions n.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
