V125BC [204]

Answer:

$\frac{2}{5}\vec{a}+\vec{b}$

Step-by-step explanation:

$\vec{DE}=\vec{DB}+\vec{BE}$

$=\frac{3}{5}\vec{OB}+\frac{1}{5}\vec{BC}$ $\left\{OD:DB=2:3,BE:EC=1:4\right\}$

$=\frac{3}{5}\left(\vec{OA}+\vec{AB}\right)+\frac{1}{5}\left(\vec{BA}+\vec{AO}+\vec{DC}\right)$

$=\frac{3}{5}\left(\vec{a}+\vec{b}\right)+\frac{1}{5}\left(-\vec{b}-\vec{a}+\vec{3b}\right)$

$=\frac{2}{5}\vec{a}+\frac{2}{5}\vec{b}+\frac{3}{5}\vec{b}$

$=\frac{2}{5}\vec{a}+\vec{b}$

Reil [10]

Answer:

$\frac{11}{20}$

Step-by-step explanation:

Let x is the total population of the world.

Therefore, by the condition given the population of North America is $\frac{2x}{25}$

Again it is given that $\frac{11}{250}$ fraction of the world's population lives in the United States of America.

So, $\frac{11x}{250}$ is the population of USA.

Therefore, the fraction of the population of North America that is the population of USA will be $\frac{\frac{11x}{250} }{\frac{2x}{25} } =\frac{11}{20}$ (Answer)
