For the scores 1, 0, 2, 4, what is the value of Σ(2X)?

When you see Σ(2X), think about factoring the constant 2 out of the summation. This means Σ(2X) = 2 ΣX. Add the X values first: 1 + 0 + 2 + 4 = 7. Then multiply by 2 to get 14. You can also add the doubled values directly: 2, 0, 4, 8 sums to 14. So the value is 14.
