Usimov [2.4K]

To solve this problem you must apply the proccedure shown below:

1. You have the following expression given in the problem above:

mn - 4m - 5n + 20

(mn-4m)+(-5n+20)

3. Now, choose the greatest common factor of each group:

m(n-4)-5(n-4)

Determine whether the variable is qualitative or quantitative.Favorite basketball played
wlad13 [49]

Answer:

\text{Qualitative}

Explanation:

Here, we want to get if the given variable is qualitative or quantitative

While qualitative describes the presence of a quality, quantitative speaks about count or number

Thus, what we have here is that we are talking about likeness and not about the count of basketball players. Thus, in this case, a certain basketball player is liked to be called a favorite because of some of the qualities he/she possesses

Thus, we can conclude that the variable is qualitative
