Which statement is supported by the information in the dot plots above?
A In comparing the shape of the data for the two dot plots, Homeroom A has more students who
spend more than 3 hours on reading than Homeroom B.
B in comparing the shape of the data for the two dot plots, Homeroom A has twice as many
students who spend 2 or less hours on reading as Homeroom B.
C in comparing the spread of the data, Homeroom A has a larger spread than Homeroom B.
Din comparing the centers of the data, Homeroom A has a center of 3 hours and Homeroom B
has a center of 5 hours.

the correct answer is 5 6 and 7

sine

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
