The chance of an IRS audit for a tax return with over $25,000 in income is about 2% per year. We are interested in the expected number of audits a person with that income has in a 6-year period. Assume each year is independent. Part (a) In words, define the Random Variable X. the number of audits the IRS does each year the number of audits the IRS does every 6 years for a person who has an income over $25,000 the number of audits a person who has an income over $25,000 receives in a 6-year period the yearly income of a person Part (b) List the values that X may take on. X = 1, 2, 3, ... X = 1, 2, 3, ..., 98, 99, 100 X = 0, 1, 2, ..., 5, 6 X = 1, 2, 3, ..., 5, 6 Part (c) Give the distribution of X. X ~ ,

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.

central angle of a triangle has the same measure as its intercepted arc.
