<h3>What is an inequality?</h3>
An inequality is a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following:
- Less than or equal to (≤).
- Greater than or equal to (≥).
Given the following system of inequalities:
3y > 2x + 12 ⇒ 3y - 2x > 12
2x + y ≤ -5

The product of the frequency and PlayCount gives the number of songs
played from the information in the histogram.
Correct responses (rounded to the nearest whole integer)
1. 2%
2. 27 PlayCount per song
3. 68%
<h3>How does one analyze an histogram?</h3>
1. The given data from the histogram is presented in a tabular form as follows;
![\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|}f&899&224&126&96&71&52&39&41&44&23&14&12&3&4&3\\x&10&20&30&40&50&60&70&80&90&100&110&120&130&140&150\end{array}\right]](https://tex.z-dn.net/?f=%5Cbegin%7Btabular%7D%7B%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7C%7Df%26899%26224%26126%2696%2671%2652%2639%2641%2644%2623%2614%2612%263%264%263%5C%5Cx%2610%2620%2630%2640%2650%2660%2670%2680%2690%26100%26110%26120%26130%26140%26150%5Cend%7Barray%7D%5Cright%5D)
The percentages of song that where played over 100 times is given as follows;
∑f = 899+224+126+96+71+52+39+41+44+23+14+12+3+4+3 = 1651
Number of songs played over 100 times = 14 + 12 + 3 + 4 + 3 = 36
2. Mean of a frequency distribution is given as follows;
Where;
x = The PlayCount
From MS Excel, we have;
∑f·x = 44410
Which gives;
3. Number of songs played less than 20 times = 899 + 224 = 1,123
