confusion with the MACHcrit and Mach Trimmer

Do jets fly above MACHcrit?

Whats the relationship between MMO and MACHcrit?

using the 737 800 as an example

What effects the MACHcrit number? is it AOA and weight...

I know on the 737 800 the mach trimmer comes into effect automatically above
mach number .615
Is this because the aircraft will be cruising at, near or above the MACHcrit number.

If the MACH trimmer is U/S does this effect our cruising speed? Are we limited to a certain value below MACHcrit?

Im preparing for an interview and just wanna make sure its clear in my head so I can talk about it if asked.
