A vacuum manufacturer runs tests on a feature that prevents overheating in its machines and finds that the range of failure rates is 18% and the mean failure rate is 17%. Should the manufacturer recall the machines already sold? Yes, because there is a high range of failure. Yes, because there is a high failure rate and range. No, because there is a low mean failure rate. Maybe, depending on the sample size.

the correct answer is 5

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.
