Iva is studying whether students gain weight during their first year of college. She collects weights from all the incoming freshmen in the fall, then collects weights from them again at the end of the spring term. Which is the term for the correlation she finds when she compares the fall and spring weights of the students?

Autocorrelation

Step-by-step explanation:

Autocorrelation seeks to measure the level of correlation between values of the same variables across different observations in the data.

Iva is autocorellating because she wants to measure if students add weight during their first year of college, so the variables she's measuring across broad is the weight which she took at fall then at spring in order to ascertain the difference in the weight in the first year. Measuring of the same variables at different times in order to ascertain changes in the variables measured is autocorrelation.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
