Answer 1

Answer:

The population of the country be in 2030 is $1.86\times 10^{10}$

Step-by-step explanation:

The population of a country in 1950 was $6.2\times 10^7$

The population in 2030 is  projected to be $3 \times10^2$ times the 1950 population.

If the projection is correct.

which means the population in 2030 is  projected to be $3 \times10^2$ times the 1950 population.

i.e. population of the country be in 2030 is

$P=(3 \times10^2)\times (6.2\times 10^7)$

$P=(3\times6.2)\times (10^2\times 10^7)$

$P=18.6\times 10^9$

$P=1.86\times 10^{10}$

Therefore, the population of the country be in 2030 is $1.86\times 10^{10}$
