Mathematics
A scientist investigated the relationship between the weight of a toy boat and the time it took for the boat to float 100 ft down a stream which was moving at a constant speed. The wind current above the stream was blowing at a constant speed in the opposite direction of the stream. The scientist recorded the experimental data in a table.
(1) Describe the relationship between the weight of the boat and the time it took to float 100 ft down the stream. Is there a positive or negative correlation between the two variables? How do you know?
(2) What is the numeric value of the correlation coefficient to the nearest hundredth? Interpret its meaning.
(3) Consider the context of the situation. Is the correlation between weight and time likely due to causation? Justify your answer.

Ответ:
( 1. ) Negative Correlation.
Use bottom info to Justify answer.
Step-by-step explanation:
As x increases y decreases = Positive Correlation
As x increases y decreases = Negative Correlation
As x increases y stays the same = No Correlation.
Hope this helps. :)
