The average life of a motorcycle is 7 years with a standard deviation of 2 years. If the manufacturer is willing to replace only 5% of the motors that fail, for how many years the company offer a replacement guarantee ? Assume that a motorcycle's life follows a normal distribution

the answer is c)8

step-by-step explanaction:

what "following statement"?

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.

answer: the answer is ann
