During this period, the probability distribution of his systolic blood pressure reading had a mean of 130and a standard deviation of 6 . If the successive observations behave like a random sample from thisdistribution, find the mean and standard deviation of the sampling distribution of the sample meanfor the three observations each day.

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.
