1 x 12=12
2x6=12
Answer:
{∅, {a}, {b}, {a,b}}
Step-by-step explanation:
The value of power of a set is generalized by using the formula,
Power of a set (P) = 2^n where n is the number of element in the set.
Given two distinct elements a and b say;
A = {a,b}
n(A) = 2 i.e the number of elements in the set is 2. Therefore the power of the set will be 2^n which gives 2^2 = 4.
P(A) = 4 means there are 4 subsets of the given set. Subsets are sets of elements that can be found in the set. The subsets of element A will be;
{∅, {a}, {b}, {a,b}} which gives 4 elements in total.
Note that empty set ∅ is always part of the subset of any given set
5x = 6x-7
subtract 6x from each side
-x=-7
x=7
Answer:
55
Step-by-step explanation:
Combination will be used here as teams are a group.
So using combination:
<em>No. of combination of 'n' things taken 'r' at a time</em>
<em>
=
</em>
here n = 11 ,
r = 9
11<em>C</em>9 <em>=
=
</em>
11<em>C</em>9<em> =</em><em> 55</em>
<em>Which are the possible 9 player starting lineups</em>
