Answer: 32
Step-by-step explanation:
When the set has <em>n</em> elements, the power set has 
elements. This also gives us the cardinality of the power set, which is what we are looking for.
A = {2,3,9,7,5}
(1) 2
(2) 3
(3) 9
(4) 7
(5) 5
<em>n</em> = 5
32
Answer=1 21/100 or 1.21
121/100 is equivalent to 1 21/100
you can solve for this by subtracting 100, the denominator, from 121, the numerator. 121-100=21. So we know that 121/100 can be simplified to one whole with 21/100 remaining...
1.33333333333 is the answer
