The article "Statistical Modeling of the Time Course of Tantrum Anger" (Annals of Applied Stats, 2009: 1013-1034) discussed how anger intensity in children's tantrums could be related to tantrum duration as well as behavioral indicators such as shouting, stamping, and pushing or pulling. The following frequency distribution was given (and also the corresponding histogram): 0--<2: 136 2--<4: 92 4--<11: 71
11--<20: 26 20--<30: 7 30--<40: 3
Draw the histogram and then comment on any interesting features.

Step-by-step explanation:

8y^50

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.
