If two events are correlated, what must be true?(1 point) One event caused the other. Both events have the same result. Both events have the same cause. The events tend to happen together

One event caused the other  

Explanation:

A correlation refers to how related are two or more variables among each other.

Two events are correlated if the result of one of them depends on the result of the other event. Also, the probability of one of them happening will be conditioned by the occurrence of the other event.  

There are different types of correlation. When two correlated variables or events have a causal relation, this means that one of them occurred because the other one occurred first. For example, let us think about a dolphin cranium. We might measure two variables, the rostrum length and the skull length. The longer the rostrum is, the longer the skull will be. The occurrence of a longer rostrum implies a longer skull. This two events are positively correlated.    

Although not every correlated event is due to causality, whenever causality occurs between two variables, it means that they are correlated.    

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )
