Which fund bond fund would I be better off with over the next 30 years?

Got a new 401k plan and I am setting up very balanced contributions and I can't quite figure out this calculation one which to choose

FXNAX has a yield of 2.95% TTM expense ratio of .03

BRHYX has a yield of 6.77% TTM but an expense ratio of .51

Dividends are going to be reinvested. Which fund would I end up better off long term with? How do you calculate the difference between yield and expense ratio?
