Nyla writes 1/4 of a page and 1/8 of a minute. how much time does it take her to write a full page ? answer

grin007 [14]

For this case we can make the following rule of three:
1/4 --------> 1/8
1 ----------> x
From here, we clear the value of x.
We have then:
x = (1 / (1/4)) * (1/8)
Rewriting:
x = 4 * (1/8)
x = 4/8
x = 1/2 minutes
Answer:
it takes her 1/2 minutes to write a full page

Which of the following correctly compares the uses of bar graphs versus pie charts? bar graphs show patterns in data with variab

saw5 [17]

Answer:

<h3><em>Bar graphs show data involved in distinct categories that do not overlap; whereas, pie charts show data as parts out of a whole (such as out of 100%).</em></h3>

Step-by-step explanation:

A bar graph, also called a bar chart, is used to present categorical variables, which involves rectangular bars with a correlation between a specific category and the frequency of them, this graphs can be also called histograms. It's used in statistics to describe a bunch a data, separating them in categories. This charts can be horizontal or vertical, and an important characteristics is that it's applied to represent discrete categories, that is, values expressed with whole numbers. (An example is attached).

On the other hand, pie charts, or circular charts, are used to indicate proportions from a whole part, like a pie or cake, you have a whole and 100% data and you divided into slices. For example, from the whole population in the U.S. we could divide it by ethnicity, parts from a whole, like show the image attached.

<h3>Therefore, based on each definition, the correct answer is:</h3>

<em>Bar graphs show data involved in distinct categories that do not overlap; whereas, pie charts show data as parts out of a whole (such as out of 100%).</em>
