Histograms are useful when we have data which can be divided into several classes or groups. The histogram shows the trend of each class and the trend among the different classes. For example when we have about 50 different values ranging from 1 to 20, it will be a better approach to draw a histogram in this case by dividing the data into small ranges e.g 1 to 4, 5 to 9 and so on and counting the frequency for each class.

Dot plot is useful when we have a small number of individual values. In this case we can visualize how many times each individual value occurred in the data. This is useful when the number of values in the data is less.

In the given scenario, we have 12 values in total ranging from 1 to 5. So making a dot plot would be the best choice. A histogram would not be useful in this case.

Therefore, the correct answer is option D. Dot plot, because a small number of scores are reported individually

Step-by-step explanation:

Number of sections = 3

Number of rows in each sections = 3

Number of square pieces in each row = 15

So, the number of squares that will be in the completed quilt would be

3\times 3\times 15\\\\=9\times 15\\\\=135

Hence, there are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.
