Answer:

Step-by-step explanation:
A function is given

Plug values of x and evaluate




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

Sorry i don’t understand the question can you reply to this and comment
Answer:
1st Graph
Step-by-step explanation:
A simple way to test if a relation may be taken as a function is by applying the Vertical Line Test. If a Vertical Line crosses the graph only once, then it is a function. In this question, only the first one can be considered to be a function.
Because in other words, only the first graph shows one value for x corresponding to another for y value. Not the case for the second and the third graph displaying two values for x for each y value.
Answer:
A
5/2 for line 1
5/2 for line 2
5/2 for line 3
B they are all parallel because the have equal slope
