The graph below shows the heights and arm spans of students in a classroom. height and arm span of students based on the graph, which is the best prediction of the height of a student with an arm span of 143 cm?

143 cm

Step-by-step explanation:

Using the graph attached, it follows that the arm span is directly proportional to the height of students. Evidently, when the height is 160 the arm span is also 160, other values follow the same order such as 180. Marking at the point when arm span is 143 from the graph, the point coincides with height of 143 cm. Therefore, the height is 143 cm

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

step-by-step explanation:

i think you should think about the question and not look online.
