Work: Calculate the value of equation -(150/350)*log(2,150/350)-(150/350)*log(2,150/350)-(50/350)*log(2,50/350) .
Question type: Mathematical calculation
Solution:
-(150/350)*log(2,150/350)-(150/350)*log(2,150/350)-(50/350)*log(2,50/350)
=-0.428571*log(2,150/350)-(150/350)*log(2,150/350)-(50/350)*log(2,50/350)
=-0.428571*(-1.222394)-(150/350)*log(2,150/350)-(50/350)*log(2,50/350)
=-0.428571*(-1.222394)-0.428571*log(2,150/350)-(50/350)*log(2,50/350)
=-0.428571*(-1.222394)-0.428571*(-1.222394)-(50/350)*log(2,50/350)
=-0.428571*(-1.222394)-0.428571*(-1.222394)-0.142857*log(2,50/350)
=-0.428571*(-1.222394)-0.428571*(-1.222394)-0.142857*(-2.807356)
=0.523883-0.428571*(-1.222394)-0.142857*(-2.807356)
=0.523883-(-0.523883)-0.142857*(-2.807356)
=0.523883--0.523883-(-0.40105)
=1.047766-(-0.40105)
=1.448816
Answer:-(150/350)*log(2,150/350)-(150/350)*log(2,150/350)-(50/350)*log(2,50/350)=1.448816
