The results of a common standardized test used in psychology research is designed so that the population mean is 110 and the standard deviation is 50. A subject earns a score of 95. What is the z-score for this raw score? z-score =

i could probably can you me with a question of mine?

step-by-step explanation:

x=half

step-by-step explanation:

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.
