What does a standard score measure?

a. the number of standard deviations that are present under a normal curve
b. the number of standard deviations a measurement is from the highest value
c. the number of standard deviations a measurement is from the lowest value
d. the number of standard deviations a measurement is from the mean

Option D) The number of standard deviations a measurement is from the mean

Step-by-step explanation:

Standard Score:

Thus, standard score can be defined as:

Option D) The number of standard deviations a measurement is from the mean

-4

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.
