Answer:
a
the first answer
Step-by-step explanation:
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

Forgive me if wrong
The answer should be -14(2+v^6) if I’m correct
He should guess about 34 times.
When you are rolling two dice there are 36 probabilities. In order to get an 8, there are 5 possibilities.
2 + 6, 3 + 5, 4 + 4, 5, + 3, 6 + 2
Therefore, the chances of an 8 are 5/36. Multiplying this by 250 gives us about 34.
The law of large numbers helps because it says the more rolls that take place, the more likely we are to get close to the expected value. With 250 rolls we should get pretty close.
