Answer:
D) 1980 to 2000
Step-by-step explanation:
Finding the average rate of change in each interval to determine the greatest one.
Production per interval
1950-1960 = [tex](21-11) \ million[/tex] = 10 million
1960-1970 = [tex](41-21)\ million[/tex] = 20 million
1970-1980 = [tex](71-41)\ million[/tex] = 30 million
1980-2000 = [tex](161-71)\ million= 90[/tex] million
Rate of change (1950-1960)= [tex]\frac{10}{11} \times 100= 90.90\%[/tex]
Rate of change (1960-1970) = [tex]\frac{20}{21} \times 100= 95.23\%[/tex]
Rate of change (1970-1980)= [tex]\frac{30}{41} \times 100= 73.17\%[/tex]
Rate of change (1980-2000)= [tex]\frac{90}{71} \times 100= 126.76\%[/tex]
∴ rate of change between 1980 to 2000 is 126.78%
