Answer: Option D
D. 0.92
Step-by-step explanation:
The correlation coefficient "r" is a number between -1 and 1 that indicates how related are two variables X and Y.
The stronger the nearest correlation is, the value of r a -1 or a 1.
A negative correlation indicates that when X increases Y decreases.
A positive correlation indicates that when X increases Y increases.
A correlation close to zero implies that there is very little correlation of the variables. When this happens, the points are scattered in the graph.
In this case you can see in the graph that the points are not scattered, but aligned. You can also observe that when X increases Y increases also.
This allows us to conclude that the correlation is strong and positive. Therefore the correct option is option D.
The greatest common factor (GCF) of 48 and 78 is: 6
Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Factors of 78: 1, 2, 3, 6, 13, 26, 39
The common factors between the two numbers are 1, 2, 3, and 6, but considering 6 is the highest number out of them, it is the greatest common factor.
There is a difference of 11 but as a percent that would be 44%
