What is the final step to be performed when computing σ(x - 2)2? ?

σ is a symbol for summation that means that it is used to add all the vales of the equation in the range for example taking 0<x<4 and x is an integer so Ď(x - 2)^2= (1-2)^2+(2-2)^2+(3-2)^2 The options were a. Square each value b. Subtract 2 points from each score C. Sum the squared values d. Subtract 22 from each X2 value As we can see above the answer is C. Sum the squared values

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
