A popular restaurant does not take reservations. As a result, there is usually a waiting time before you can be seated. Assume the waiting time before being seated is normally distributed with a mean of 22 minutes and a standard deviation of 5 minutes. What is the probability that the waiting time will exceed 30 minutes? (Round to the nearest tenth)

c

step-by-step explanation:

because of the levels

its a straight line parallel to the time axis

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.
