Since figure t is twice the size of figure s, figure t would be twice the size of s. hence the answer would be a scale factor of 2.
I believe it is positive so option 2
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 =
= 10 million
1960-1970 =
= 20 million
1970-1980 =
= 30 million
1980-2000 =
million
Rate of change (1950-1960)= 
Rate of change (1960-1970) = 
Rate of change (1970-1980)= 
Rate of change (1980-2000)= 
∴ rate of change between 1980 to 2000 is 126.78%
(40+41+41+45+48+48+49+49+49+40)/10 = 460/10 = 46
mean = 46
