The scores of an eighth-grade math test have a normal distribution with a mean u = 83 and a standard deviation
din's test score was 92, which expression would she write to find the z-score of her test score?

5050 i think

step-by-step explanation:

the correct answer is x/3+10≥32

hope this !

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.

step-by-step explanation:

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
