The population of Greenville is currently 50,000 and declines at a rate of 1.2% every year. This models:

Every year they are losing 600 people a year.

Step-by-step explanation:

You take 50,000/100= 500 x 1.2=600

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.

the number 100 represents the number of trials in the experiment.
