Question

What is the mean when the summation of fiui is 12 and fi is 94​

Answer 1

Step-by-step explanation:

Thank you for asking this question, here is your answer:

ui = x base i A/ h

ui = x base i - 25/ 10 (this is given)

A = 25

h = 10

x = A + h x sigma (fiui) / sigma(fi)

= 25 + 10 x 20/100

= 25 + 2

= 27

27 is the final answer for this question.
