Fair coin means P(heads) = 1/2 for each flip.
The three flips are independent, so multiplication rule applies.
P(head,head,head)=(1/2)(1/2)(1/2)=1/8
when solving for y
y = -7x/3-6
so y does not vary directly with x
the answer is no
If you mean lowest terms as in fully simplified, then your fraction "2/11" is already in lowest terms.
Lowest terms mean that your numerator and denominator have no common factors apart from 1.
2 and 11 don't have any common factors, therefore 2/11 is in lowest terms already.
It's an equilateral triangle, therefore
AB = BC = BA
We have the equation:


<h3>Answer: BC = 3</h3>
