The median rainfall during a spring storm in the lowlands is about 4 mm less than a spring storm in the highlands. the mean rainfall for the lowlands is about 3 mm less than for the highlands. why is there a difference in the central measures for each data set?

Median is just the value that is neither the highest nor the lowest compared with the other values in the set

Mean is just the average of the numbers which is found out by adding up all the numbers then dividing the sum by the number of values in the set

The mean and the median are different  because the data for the highlands has more variation than the data for the lowlands. The mean is affected by the outliers in the lowlands data.

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

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
