Work: Calculate the value of equation ((1-2.1)^2+(3-2.1)^2+(3-2.1)^2+(2-2.1)^2+(1.5-2.1)^2)/(5-1) .
Question type: Mathematical calculation
Solution:
((1-2.1)^2+(3-2.1)^2+(3-2.1)^2+(2-2.1)^2+(1.5-2.1)^2)/(5-1)
=((-1.1)^2+(3-2.1)^2+(3-2.1)^2+(2-2.1)^2+(1.5-2.1)^2)/(5-1)
=(-1.1^2+0.9^2+(3-2.1)^2+(2-2.1)^2+(1.5-2.1)^2)/(5-1)
=(-1.1^2+0.9^2+0.9^2+(2-2.1)^2+(1.5-2.1)^2)/(5-1)
=(-1.1^2+0.9^2+0.9^2+(-0.1)^2+(1.5-2.1)^2)/(5-1)
=(-1.1^2+0.9^2+0.9^2+(-0.1)^2+(-0.6)^2)/(5-1)
=3.2/(5-1)
=3.2/4
=0.8
Answer:((1-2.1)^2+(3-2.1)^2+(3-2.1)^2+(2-2.1)^2+(1.5-2.1)^2)/(5-1)=0.8
