[1/1 Formula]
Work: Calculate the value of equation -(9/14)*(lg(9/14))-(5/14)*(lg(5/14)) .
Question type: Mathematical calculation
Solution:
-(9/14)*(lg(9/14))-(5/14)*(lg(5/14))
=-0.642857*(lg(9/14))-(5/14)*(lg(5/14))
=-0.642857*(lg0.642857)-(5/14)*(lg(5/14))
=-0.642857*(-0.191886)-(5/14)*(lg(5/14))
=-0.642857*(-0.191886)-0.357143*(lg(5/14))
=-0.642857*(-0.191886)-0.357143*(lg0.357143)
=-0.642857*(-0.191886)-0.357143*(-0.447158)
=0.123355-0.357143*(-0.447158)
=0.123355-(-0.159699)
=0.283054
Answer:-(9/14)*(lg(9/14))-(5/14)*(lg(5/14))=0.283054
