In 2011, the birthrate in hungary was 9 (per 1000 people). in the same year, the death rate in hungary was 13 (per 1000 people). what was hungary's approximate growth rate in 2011? a) an increase of 117 ( per 1000 people) b) an decrease of 22 ( per 1000 people) c) a decrease of 4 ( per 1000 people) d) an increase of 22( per 1000 people)

The correct answer is option (C).

Explanation:

Birth rate in Hungary in 2011 = 9 (per 1000 people)

Death rate in Hungary in 2011 = 13 (per 1000 people)

Growth rate = Birth rate - Death rate :

9(per 1000 people) - 13 (per 1000 people)= -4(per 1000 people)

Negative sign indicates that there will be a decrease in growth rate by the magnitude of 4 per 1000 people.

Hence, the correct answer is option (C).

there are 35 white marbles
