Exhibit 2 presents the cost of treating each of the 426 million cases of illness. Average treatment costs varied by country. Ukraine maintained the highest cost of treatment for all diseases at $62 for malaria, $1,113 for meningitis, $21 for pertussis, $264 for pneumonia, and $42 for rotavirus.xhibit 2 presents the cost of treating each of the 426 million cases of illness.

Frequency Polygons. A frequency polygon is another way to show the information in a frequency table. It looks a little bit like a line graph. To make a frequency polygon, you just need to plot a few points and then join the points by straight lines.he reason itâs called a polygon is because the line sort of forms a plane shape with the horizontal axis as one side of the shape: Now a frequency polygon and a histogram both show the same information, but in a different way.
Their fundamental frequency is thenk = 2ÏL = 1, and their Fourier series representations involve terms likea 1 cosx, b 1 sinxa 2 cos2x, b 2 sin2xa 3 cos3x, b 3 sin3xWe also include a constant term a 0 /2 in the Fourier series. Thisallows us to represent functions that are, for example, entirely abovethe xâaxis. With a suï¬cient number of harmonics included, our ap-proximate series can exactly represent a given function f(x)f(x) = a 0 /2 + a 1 cosx+a 2 cos2x+a 3 cos3x+...+ b 1 sinx+b 2 sin2x+b 3 sin3x+...
