» What is the mean and MAD of this data set?

The mean is 7, and the MAD ( Sorry, I know what it is just not what it abbreviates ) is about 4.29, so your answer is the very bottom one.

Hope this helps, if not, or you need the explanation, comment below please!!!

answer: D

Step-by-step explanation:

Mean= total sum/ total number

= 56/7

=8

mean absolute deviation:

MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$

where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

triangle and cube

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.
