<u>Answer:</u>
If the spool has 10 cm of circumference or perimeter, this means that 10 cm of thread fits the whole circumference of the spool, which also means that
<h2>
1 unwind is equivalent to 10 cm of thread.
</h2>
Then, we have to make the following question:
If 10 cm of thread is equivalent to 1 unwind, to how many unwinds is equivalent 80 cm of thread?
If we want to know how many time does Alex need to unwind the spool, we can use the following relation also called the <u>Rule of Three:
</u>
<u>
</u>
The answer is:
Alex must unwind the spool 8 times in order to get 
cm of thread
No, because the data display the percentage of time spent by each age group, not a relative frequency compared with the whole.
The correct option is C.
<h3>
What is pie chart?</h3>
The “ pie chart” is also known as a “circle chart”, dividing the circular statistical graphic into sectors or sections to illustrate the numericical value.
Given
People of different ages were asked the question "Do you listen to audiobooks?
" The frequency table displays the percentage of "yes" responses for different age groups. 13 to 17, 8 percent; 18 to 25, 15 percent; 26 to 35, 23 percent; 36 to 45, 45 percent; 46 and over, 48 percent.
Considering that the data displays the percentage of time spent by each age group, not a relative frequency compared to the whole, a pie chart would not be appropriate.
- Pie charts are used to indicate relative frequency of each group, when the whole combines to 100%.
- In this problem, the sum of the percentages is not 100%, hence, it does not indicate relative frequency, and the third option is correct.
Hence, No, because the data display the percentage of time spent by each age group, not a relative frequency compared with the whole.
