Information collected for alternative purposes prior to the study is referred to as

Secondary Data

Step-by-step explanation:

Primary and secondary data are concepts in market research on the basis of who collected or when the data was collected.

Unlike primary data which is a real-time data collected or gathered for the research problem at hand, secondary data is collected for other purposes rather than the problem at hand. Secondary data is one that is gathered by someone else and many times it's in the past. Therefore, secondary data can be considered as information collected for alternative purposes prior to a study.

Hope this helps!

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

i belive those are the ones that are under 90 degreese.
