The table says that the x value represents the number the years since 1985. To find the number of bald eagle pairs in 1998, we need to calculate x:
1998 - 1985 = 13
Now plug 13 in for x to find y:
y = 312.5(13) + 1562.5
y = 5625
-2-3x=3+1x
-2-3=1x+3x
-5=4x
x=-1.25
Answer:
d. Since fertilizer is in both data sets and is positively correlated to both tree height and fruit yield, it is like that tree height and fruit yield are also positively correlated.
Step-by-step explanation:
The correlation refers to the relationship between two or more variables i.e how they are interrelated to each other. It can be positive, negative, perfect, etc
As we can see in the figure that in both the data sets the fertilizer contains the same values which depict that they are positively correlated with respect to the height of tree and fruit yield that derives that the height of tree and fruit yield is also positively correleated
Here positive correlation means that the two variables moving in a similar direction i.e if one variable increased so the other is also increased
Therefore the option d is correct
