Cumulative Frequency for Each Brightness Value Solution

Follow our step by step solution on how to calculate Cumulative Frequency for Each Brightness Value?

FIRST Step Consider the formula

K i = \frac{1}{n} \cdot \sum (x, 0, N max, f[BV i])

Next Step Substitute values of Variables

∴

K i = \frac{1}{40px} \cdot \sum (x, 0, 17.48W/m², 80)

Next Step Prepare to Evaluate

∴

K i = \frac{1}{40} \cdot \sum (x, 0, 17.48, 80)

LAST Step Evaluate

∴

K i = 36
