We know that 2/3 of all students watch TV shows on their computers.
And 234 students were in that survey.
2 / 3 * 234 = 156
Answer: 156 students watch shows on their computer.
Considering the period of the cosine function, it is found that it takes 40 seconds for the wheel to complete one turn.
<h3>What is the period of the cosine function?</h3>
The cosine function is defined by:
f(x) = acos(bx + c) + d.
For the period, we have to look at coefficient b, and the period is:
P = 2π/|B|
For this problem, the function is given by:
h(x) = 15 cos(π/20)
Hence B = π/20, and the period is:
P = 2π/|B| = 2π/(π/20) = 2 x 20 = 40 seconds.
Hence it takes 40 seconds for the wheel to complete one turn.

<span>Actually in this whole world the major ill-literates are definitely women from many decades for sure, The main reason being most of them women where made or treated to be like that by our society any where any place in this world ie, just for giving birth to kids and looking after them and also the house chores, which was or is one of the main reason 1 in 5 adults cannot read or write where most of them are women, but now in the modern technology generation its slowly changing and equality will surely come in the next future.</span>
