A distribution of values is normal with a mean of 160 and a standard deviation of 15. From this distribution, you are drawing samples of size 23.
Find the interval containing the middle-most 74% of sample means:
Enter your answer using interval notation. In this context, either inclusive or exclusive intervals would
be acceptable. Your numbers should be accurate to 1 decimal places. Answers obtained using exact
z-scores or 2-scores rounded to 3 decimal places are accepted.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

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.

step-by-step explanation:
