Aresearch company is looking at the correlation between the years since 1970 and the average amount of years that couples stay married. use complete sentences to explain how the data below indicates a non-linear model.
time (in years) since 1970: 0, 10, 20, 30, 40
average age of a marriage (yrs.): 10, 11.2, 13.9, 17.2, 29

Answer and Step-by-step explanation:

Since we have given that

Time                Average age of a marriage

0                                  10

10                                 11.2

20                                13.9

30                                17.2

40                                29

We need to show that the above data indicated a non linear model.

For this it is enough to show that slope is different:

So, we consider the slope for first 2 points:

(0,10) and (10,11.2)

So, slope becomes

and similarly, (10,11.2) and (20,13.9)

so,

So, it becomes non linear model.

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
