The mean age of swimmers for all of these teams is 10. what does the large mad tell you?

MAD which is know as mean absolute deviation gives us the mean of the absolute deviation of each of the data points from the mean of the data set.

The large mean tells us that there is a greater variability in the data i.e. the data is spread out which leads to the larger deviation of  the data points from the mean of the data.

Here the mean age of swimmers for all the teams is 10

Hence, the larger MAD tells that there are swimmers whose age are much more than 10 and hence the deviation from mean will be more and hence leads to larger MAD.

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
