4 log 3+2 log 5=..............
if log x base root 3=4 then x=........
if a=b square=c cube then log ab base c=..........
SETS:
IF A&B be two non empty sets then A-B=...........
if n(A)=10,n(B)=5 that A,B are disjoint set then n(A union B)=.............
if the set A has 64 subsets in it then n(A)=.............
set of multiple of 5 is...........set
the identity set under intersection of sets is..........
STATISTICS:
when it is more convenient to use grouped data for analysis
is the mode always at the centre of the data
can mode be calculated for grouped data with unequal class size
is the result obtained byu all the 3 methods the same
does the mode change if another observation is added to the data
wat r the answers for sets question
1)A intersection B dash (') 2)15 3)6 4) infinite 5) miu.
