Vladimir79 [104]

Answer:

Qualitative and Neither

Step-by-step explanation:

Quantitative data is such a data which can be measured or calculated i.e. which is defined only in terms of numbers. In simple words we can say that numeric data is the Quantitative data.

On the other hand, qualitative data describes the characteristics, attribute or quality of the objects. This type of data is not measured or calculated.

The data which we are dealing with is "Kind of pizza". The kind/flavor of pizza is an attribute or characteristic of pizza. So from here it is clear that the data is Qualitative. Though numbers are assigned  to different flavors, these numbers are just for identification of the flavor on the order form.

The terms discrete and continuous can only be used when the data is Quantitative. Qualitative data cannot be referred to as discrete or continuous data, even if some numbers are assigned to data.

Therefore, the answers are: Qualitative and Neither

What percent of the June budget was for Tim's Chevron and car (to the nearest tenth)?
Maurinko [17]

Answer:

D. 17.4%

Step-by-step explanation:

To find a percent, divide the part by the whole and multiply by 100.

The part is the sum of Tim's Chevron and Car:

$23 + $272 = $295 = part

The total is $1695 = whole

percent = part/whole * 100%

percent = 295/1695 * 100%

percent = 0.174041 * 100%

percent = 17.4%

Answer: D. 17.4%
