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.
Harmonics are voltages or currents that operate at a frequency that is an integer (whole-number) multiple of the fundamental frequency. So given a 50Hz fundamental waveform, this means a 2nd harmonic frequency would be 100Hz (2 x 50Hz), a 3rd harmonic would be 150Hz (3 x 50Hz), a 5th at 250Hz, a 7th at 350Hz and so on.he fundamental waveform can also be called a 1 st harmonics waveform. Therefore, a second harmonic has a frequency twice that of the fundamental, the third harmonic has a frequency three times the fundamental and a fourth harmonic has one four times the fundamental as shown in the left hand side column.
