Data collected on the depth of the Mississippi River and the water discharge are given in the table: Depth Discharge (ft3) 1.59 63 2.90 97 3.10 123 3.31 254 3.31 398 4.27 550 4.55 583 6.67 603 6.79 655 6.82 726 Find r2, and interpret the results. (4 points) Select one: a. 0.81; The least-squares regression line, given by ŷ = −126.08 + 122.67x, is not a good fit for the data. b. 0.90; The least-squares regression line, given by ŷ = −126.08 + 122.67x, is a good fit for the data. c. 0.81; The least-squares regression line, given by ŷ = −126.08 + 122.67x, is a good fit to the data. d. 0.81; The least-squares regression line, given by ŷ = 122.67 − 126.08x, is a good fit to the data.

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.
