Yes it is the same as having no slope.
Answer:
2000 times 3.5% is 70, so in one year you would have 2070 dollars. 3.5 divided by 3 is about 1.16 (the six repeats), so for the next 1/3 year you would do 2070 times 1.16 percent which is 30. So, then, 2070 plus 30 is 2100 dollars in the saving account.
The range of the data is C. 160 because the biggest number, 280, subtracted by the smallest number, 120, is equal to 160.
I want to believe that it's (0, infinite).
