Which data set has a variation, or mean absolute deviation, similar to the data set in the given dot plot?

Add all the absolute deviations and divide by number of swimmers.

Step-by-step explanation:

To find the mean absolute deviation of any data we need to follow the following steps:

Start by finding the mean of the data set.

Find the absolute value of the difference between each data value and the mean.

Find the sum of the absolute values of the differences.

Divide the sum of the absolute values of the differences by the number of data values.

We can see in the picture that it already dome with first two steps so the step after that is " Add all the absolute deviations and divide by number of swimmers."

hope this helps

Step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

answer is 144
