Anewspaper publisher trying to pin-point his market’s characteristics wondered whether the way people read a newspaper is related to the reader’s educational level. a sur-vey asked adult readers which section of the paper they read first and asked to report their highest educational level. these data were recorded (column 1 = first section read where 1 = front page, 2 = sports, 3 = editorial, and 4 = other) and column 2 = educational level where 1 = did not complete high school, 2 = high school graduate, 3 = university or college graduate, and 4 = postgraduate degree). what do these data tell the publisher about how edu-cational level affects the way adults read the newspaper?

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.
