I picked up 3 female swordtails on dec 21 and added them to my tank. water test results were as followed amm=0,nitrite=0,nitrate=10,ph=7.4. then on thursday dec 22 i did a 20% water change. All fish looked good. when i awoke today i found one of my black tetras dead. I tested the water again and attained the same results.water temp 78. Black tetra was one of original fish, and i had him over a year. Old age or something else? Should i pick up another black tetra to go with the one remaining one.

Welcome to the tank!
Tetras are not very long lived fish. Also sometimes fish "just die" for no apparent reason. Honestly you need to fix your stocking. You will be at your max but you will be ok. Increase your tetra numbers to 6 for each species. And loose the silver dollar. They are also a schooling fish, but get to be a hefty size, and would way over stock your tank to keep 6 of them.
