Suppose that all the values in a data set are converted to z-scores. which of the statements below is true? a: the mean of the z-scores will be zero, and the standard deviation of the z-scores will be the same as the standard deviation of the original data values. b: the mean and standard deviation of the z-scores will be the same as the mean and standard deviation of the original data values. c: the mean of the z-scores will be 0, and the standard deviation of the z-scores will be 1.d: the mean and the standard deviation of the z-scores will both be zero.

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.
