No. Solo queueNo.
Ranked MMR doesand normal MMR are definitely not affect Teamsynchronized.
You can see it when mostly any LoL pro (or anyone who improved in rankeds since last normal game) plays normals - they stomp hard, because their normal MMR is much lower than their more accurate assessment of their skill - their ranked MMR. If in no way waysuch game their enemy team has ranked players, their ranks would reflect that unless they are in similar position (i.e. improved since last normal game) - their ranks would be much lower than that of said pro/high-elo player.
Kinda related: Solo queue MMR does not affect Team MMR in no way way; besides maybe placement matches. There are ways to test this hypothesis in a way - see http://op.gg/ for soloq and ranked team MMR or if you don't trust it's algorithms, just find a team with ranking severely below individual rankings (due to lack of communication etc), which is pretty common in lower divisions (higher up discrepancy is a bit less, by my observations)

- currently can not find Riot's information regarding this but remember reading it
- some minimal research shows that it is common knowledge.
