Sagot :
The question is an illustration of proportion and percentages
The percentage of young adults, age 18-25 were not current alcohol users is 34.92%
The attached graph represents the proportion of those that are surveyed.
From the graph, we have:
[tex]\mathbf{Total = 18.6 + 27.2 + 20.8 + 11.3}[/tex]
[tex]\mathbf{Total = 77.9}[/tex]
The number of young adults 18 - 25 that are not current alcohol users are:
[tex]\mathbf{Young\ adults = 27.2}[/tex]
So, the percentage of this group is:
[tex]\mathbf{\% Young\ adults = \frac{Young\ adults}{Total} \times 100\%} }[/tex]
This gives
[tex]\mathbf{\% Young\ adults = \frac{27.2}{77.9} \times 100\%} }[/tex]
[tex]\mathbf{\% Young\ adults = 0.3492 \times 100\% }[/tex]
Multiply
[tex]\mathbf{\% Young\ adults = 34.92 \% }[/tex]
Hence, the percentage of young adults, age 18-25 were not current alcohol users is 34.92%
