Question

IfUi=Xi-25/10,sigmaFiUi=20andsigmaFi=100,let us find the value of x​

Answer 1

Answer:

plz mark the answer as brainlist

Step-by-step explanation:

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
