if 368 teenagers in a population of 4,310 report that they have smoked at least one cigarette during the past year, to one decimal place, what percentage reported this

Respuesta :

kanest
Divide the amount of teenagers that smoked by the total population:

[tex]368 \div 4310 = 0.0853[/tex]

Multiply this decimal by 100 to convert into a percentage:

[tex]0.0853 \times 100 = 8.53[/tex]

To round to the nearest decimal place, look at the hundredths value:

8.53
3 > 5
8.53 -> 8.5

8.5% of teenagers reported that they smoked at least one cigarette.
