Tell whether the data are qualitative or quantitative.
Ulleksa [173]

Answer:

Qualitative

Step-by-step explanation:

When data is quantitative, it is describing a numerical amount. For example, if the data was "the amount of houses on the street that have a garage," then the data would be quantitative since it is representing an amount (the amount of houses.) For data to be qualitative, it should be representing a quality of some kind. For example, a qualitative sample of data could be, "scents of perfumes in a store," or, "flavors of ice cream in a diner." Since our initial data is representing a quality and not a numerical amount, the data is qualitative!

Ronch [10]

Answer:

154 minutes to process and spell check 28 pages

Step-by-step explanation:

33 Minutes to process 6 pages

If we divide both of these numbers by 6 we will get the time taken to process 1 page

33 ÷ 6 = 5.5 minutes, and 6 ÷ 6 = 1 page

So 5 and a half minutes per page

To find out how long 28 pages will take, we multiply by 28

5.5 × 28 = 154 minutes, and 1 × 28 = 28 pages

Which gives us the time of 154 minutes to process and spell check 28 pages
