The number 1,2,3,4,...,7 are randomly
divided into two non −empty subsets.
The probability that the sum of the
numbers in the two subsets being
equal is (r/s) expressed in the lowest
term. Find r+s ?
A five digits number divisible by 3
is to be formed using the number
0,1,2,3,4 and 5 without repetition
The total number of ways this can
be done is __
Let S ={1,2,3,4,...,48,49} .What is
the maximum value of n such that
it is possible to select n numbers
from S and arrange them in a circle
in such a way that the product of
any two adjacent numbers in the
circle is less than 100?
the speed v of a projectile launched at
an angle α to the horizontal is thought to
be given by :
v = [(1/k)(A + ((sin αt)/g)) + e^(−C/t) ]
where k,A, α and C are constants, t is time
and g is the gravitational acceleration.
determine the base units of A, α and C
