Work: Calculate the value of equation -(450/800)*log(2,450/800)-(300/800)*log(2,300/800)-(50/800)*log(2,50/800) .
Question type: Mathematical calculation
Solution:
-(450/800)*log(2,450/800)-(300/800)*log(2,300/800)-(50/800)*log(2,50/800)
=-0.5625*log(2,450/800)-(300/800)*log(2,300/800)-(50/800)*log(2,50/800)
=-0.5625*(-0.830075)-(300/800)*log(2,300/800)-(50/800)*log(2,50/800)
=-0.5625*(-0.830075)-0.375*log(2,300/800)-(50/800)*log(2,50/800)
=-0.5625*(-0.830075)-0.375*(-1.415037)-(50/800)*log(2,50/800)
=-0.5625*(-0.830075)-0.375*(-1.415037)-0.0625*log(2,50/800)
=-0.5625*(-0.830075)-0.375*(-1.415037)-0.0625*(-4)
=0.466917-0.375*(-1.415037)-0.0625*(-4)
=0.466917-(-0.530639)-0.0625*(-4)
=0.466917--0.530639-(-0.25)
=0.997556-(-0.25)
=1.247556
Answer:-(450/800)*log(2,450/800)-(300/800)*log(2,300/800)-(50/800)*log(2,50/800)=1.247556
