Answer:
Longitudinal study
Step-by-step explanation:
Information is collected over extended periods of time in a longitudinal study, but in cross-sectional, natural observation, and experimental studies, information is collected over short periods of time or in one time only. Based on the choices given, this type of study would be a longitudinal study.
The ratio would look like 63:3.5, if simplified it would look like 18:1
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Just draw a graph and plot them on the graph then count how many squares (in short) there is between them.
It would be K = -6j . I hope this helped you!
