The average X bar would be 9.78

Take all players

Add them all together, you received 137

Then divide by the total number of players 14

147/14 = 9.79 with rounding to the second placement (100ths)

Step-by-step explanation:

step-by-step explanation:

107 units

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.
