This is because once your head gets below the sand you automatically suffocate and the more you move the more you sink meaning unless rescued by a machine you won't survive. Also when suffocating your brain sends a signal to try and breathe so you squirm to get free wich makes you sink even further. You will suffocate before anyone gets to you more than likely. Otherwise the sand fills your nostrils and lungs and if eye's are open they star to be very painful because the sand is very packed and the pressure will damage your eyes very bad.
Assuming that the students
worldwide are being considered, because of the extremely large population, this
can be considered as a binomial distribution. A normal distribution is used most
usually as a fair approximation of the binomial. The mean is the expectation,
therefore:<span>
E[x] = np = (16)(0.22) = 3.52 <span>μ = 3.52 </span></span>
As some people have it wrong, waves in the water (ocean) are not waves of moving water, rather the wave is moving through the water. A wave is a disturbance of a medium not the meduim moving.
