What is the mean absolute deviation of the data set? {12, 10, 10, 8, 6, 7, 7, 12}

The MAD of  {12, 10, 10, 8, 6, 7, 7, 12} is 2.

Step-by-step explanation:

Step 1 : Add all the values Up:

Step 2 : Divide them by the number of items or numbers:

Step 3: Find the absolute deviations:

Step 4: Add all the absolute deviations:

Step 5: Find the mean:

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:

answer: 193

explanation:

200-7 = 193
