A local university claims that the incoming freshman class consists of students with a mean GPA of 3.4 with a standard deviation of 0.35. They are going to randomly place the freshmen into orientation groups of size 30. What is the probability that one of these groups has a mean GPA of 3.55 or higher?

its c or d   take a lucky guess my dude

900 degrees

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.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
