Here is how the Second Moment of ERH about Time Origin divided by Total Excess Rainfall equation looks like.

16 = 448 - (3 \cdot (3 + 1) \cdot 4^{2}) - (2 \cdot 3 \cdot 4 \cdot 10)

16 = 448 - (3 \cdot (3 + 1) \cdot 4^{2}) - (2 \cdot 3 \cdot 4 \cdot 10)

16 = 448 - (3 \cdot (3 + 1) \cdot 4^{2}) - (2 \cdot 3 \cdot 4 \cdot 10)

Second Moment of ERH about Time Origin divided by Total Excess Rainfall Solution

Follow our step by step solution on how to calculate Second Moment of ERH about Time Origin divided by Total Excess Rainfall?

FIRST Step Consider the formula

M I2 = M Q2 - (n \cdot (n + 1) \cdot K^{2}) - (2 \cdot n \cdot K \cdot M I1)

Next Step Substitute values of Variables

∴

M I2 = 448 - (3 \cdot (3 + 1) \cdot 4^{2}) - (2 \cdot 3 \cdot 4 \cdot 10)

Next Step Prepare to Evaluate

∴

M I2 = 448 - (3 \cdot (3 + 1) \cdot 4^{2}) - (2 \cdot 3 \cdot 4 \cdot 10)

LAST Step Evaluate

∴

M I2 = 16
