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.
750,000 you round the 4 up because of the 5 next to it. Id the number to the right of it is 5 or higher you round up :)
In fraction with 1 as a numerator the larger the number the smaller the value
since 3 is the only number less than 5 it's the one that's greater
answer is 1/3

Answer:
Step-by-step explanation:
Cancel the base both side as they’re both the same.
Leaves:
2x + 1 = 3x - 2 (Lets bring letters left, numbers right)
2x - 3x = -2 -1
-1x = -3 (Change signs both sides)
1x = + 3
