The population of a country increased by an average of 2% per year from 2000 to 2003. If the population of this country was 2 000 000 on December 31, 2003, then the population of this country on January 1, 2000, to the nearest thousand would have been

A. 1 846 000

B. 1 852 000

C. 1 000 000

D. 1 500 000

B. 1 852 000

Step-by-step explanation:

Population of the country on Jan 1, 2000 =  P

r = 2%

total duration = 4 years,  :  2000, 2001, 2002, 2003

If we take the compounding of the rate of growth :

        2, 000, 000 = P (1 + 2/100)^4  = P (1.02)^4

              P =  1, 847,691

If we take the growth of the population similar to simple interest of money deposits, then :

          2, 000, 000 = P + P * 2/100 * 4

            P = 2, 000, 000 / 1.08 = 1, 851, 852

     In this case the answer is B

87%

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
