The slope is negative one
there is about a 4% chance that they answer yes and about an 8% chance they are male.
Yes probability- 6/151≈.039 which rounds to .4 or 4%
Male probability- 12/151≈.079 which rounds to .8 or 8%
Answer: At least 7
Step-by-step explanation:
A good tip is to cut the same shape and fold it and count how many symmetry :)
Answer:
The answer is 
.
Step-by-step explanation:
First, it is important to recall that the group law is not commutative in general, so we cannot assume it here. In order to solve the exercise we need to remember the axioms of group, specially the existence of the inverse element, i.e., for each element 
there exist another element, denoted by 
such that 
, where 
stands for the identity element of G.
So, given the equality 
we make a left multiplication by 
and we obtain:
But, 
. Hence, 
.
Now, in the equality we make a right multiplication by 
, and we obtain
.
Recall that 
and 
. Therefore,
.
