Work: Calculate the value of equation ((210-202.5)^2+(160-202.5)^2+(75-202.5)^2+(280-202.5)^2+(300-202.5)^2+(190-202.5)^2)/5 .
Question type: Mathematical calculation
Solution:
((210-202.5)^2+(160-202.5)^2+(75-202.5)^2+(280-202.5)^2+(300-202.5)^2+(190-202.5)^2)/5
=(7.5^2+(160-202.5)^2+(75-202.5)^2+(280-202.5)^2+(300-202.5)^2+(190-202.5)^2)/5
=(7.5^2+(-42.5)^2+(75-202.5)^2+(280-202.5)^2+(300-202.5)^2+(190-202.5)^2)/5
=(7.5^2+(-42.5)^2+(-127.5)^2+(280-202.5)^2+(300-202.5)^2+(190-202.5)^2)/5
=(7.5^2+(-42.5)^2+(-127.5)^2+77.5^2+(300-202.5)^2+(190-202.5)^2)/5
=(7.5^2+(-42.5)^2+(-127.5)^2+77.5^2+97.5^2+(190-202.5)^2)/5
=(7.5^2+(-42.5)^2+(-127.5)^2+77.5^2+97.5^2+(-12.5)^2)/5
=33787.5/5
=6757.5
Answer:((210-202.5)^2+(160-202.5)^2+(75-202.5)^2+(280-202.5)^2+(300-202.5)^2+(190-202.5)^2)/5=6757.5
