The astronomer found that 0.017 at the stars examined were red dwarfs. if 29,000 stars or examined, how many were not red dwarfs?
If 0.017 were red dwarfs, then we have a not red dwarfs percent of:
Not red dwarfs pct = 1 - red dwarfs
Not red dwarfs pct = 1 - 0.017
Not red dwarfs pct = 0.983
For 29,000 stars, we have
Not red dwarfs = Starts * not red dwarfs pct
Not red dwarfs = 29000 * 0.983
Not red dwarfs = 28,507
If 0.017 were red dwarfs, then we have a not red dwarfs percent of:
Not red dwarfs pct = 1 - red dwarfs
Not red dwarfs pct = 1 - 0.017
Not red dwarfs pct = 0.983
For 29,000 stars, we have
Not red dwarfs = Starts * not red dwarfs pct
Not red dwarfs = 29000 * 0.983
Not red dwarfs = 28,507
