Question

Researchers count 48 marked deer and a total of 638 deer on a flight over an area. They know there are 105 marked deer. How many deer are in the area? Round to the nearest whole number

Answer 1

Answer:

Total number of deer in the area =$1396$

Step-by-step explanation:

Total sample size $=638$

Number of marked deer $=48$

Find out $\%$ of marked deer

$\% marked\ deer\ =\frac{marked\ deer }{sample\ size}\times100\\\\=\frac{48}{638}\times100\\\\=7.52\%$

Total $7.52\%$ of total number of deer are marked

let total number of deer in the area$=x$

marked deer $=105$

$=7.52\% \ of\ x=105\\\\\frac{7.52}{100}\times x=105\\\\=x=\frac{105\times 100}{752}=1395.625\approx1396$
