[1/1 Formula]
Work: Calculate the value of equation ((-1-1)^2+(-1-1)^2+(2-1)^2+(2-1)^2+(3-1)^2)/5 .
Question type: Mathematical calculation
Solution:
((-1-1)^2+(-1-1)^2+(2-1)^2+(2-1)^2+(3-1)^2)/5
=((-2)^2+(-1-1)^2+(2-1)^2+(2-1)^2+(3-1)^2)/5
=(-2^2+(-2)^2+(2-1)^2+(2-1)^2+(3-1)^2)/5
=(-2^2+(-2)^2+1^2+(2-1)^2+(3-1)^2)/5
=(-2^2+(-2)^2+1^2+1^2+(3-1)^2)/5
=(-2^2+(-2)^2+1^2+1^2+2^2)/5
=14/5
=2.8
Answer:((-1-1)^2+(-1-1)^2+(2-1)^2+(2-1)^2+(3-1)^2)/5=2.8
