13 hours is the minimum amount of hours he has to work.
70 m * (100cm)/(1m) * (1 in)/(2.54 cm) = 2755.9 in
.
<span>Rough check, 1 m = 39.36 in approx , 70*39.36 = 2755.2

I think that's how it's done. As far as explaining it goes, I can't do that. I had to ask my math teacher and she wrote the calculations down.
Answer:
1.) P(HHHT) = 1/16
Step-by-step explanation:
P(H) = 1/2
P(T) = 1/2
P(HHHT) =P(H) *P(H) * P(H) *P(T)
1/2 * 1/2 * 1/2 * 1/2
=1/16
