A. 2 based on the following reasoning: TFIDF = TF1DF = 1 908
You then know that IDF wil equal LOG (32)=0.954 Therefore, TFIDF=TF*0.954 = 1.908
TF will then round to 2
B. 4 based on the following reasoning:
TFIDF = TF1DF = 1.908
You then know that IDF wil equal LOG (3/1 )=0.477
Therefore, TFIDF=TF'0 477 = 1.908
TF will then round to 4
C. 6 based on the following reasoning: TFIDF = TF1DF = 1.908
You then know that IDF wil equal 3/1=3 Therefore, TFIDF=TF/3 = 1.908
TF will then round to 6
D. 11 based on the following reasoning: TFIDF = TF1DF = 1908
You then know that IDF wil equal LOG(3/2)=0.176
Therefore, TFIDF=TF"0.176 = 1.908 TF wil then round to 11
