Answer:
It will land 7.5 times on tails, which is rounded up to 8 times
Step-by-step explanation:
there are 2 possibilities, heads or tails
so you divide 15 in 2 and get 7.5
We know that
cos 45°=√2/2------> equation 1
in the triangle
cos 45°=m/(9√2)----> equation 2
equals 1 and 2
so
√2/2=m/(9√2)---> 9√2*(√2)=2*m-------> 9*2=2*m-------> m=9
the answer is
m=9 units
