Answers:
0.45 is a moderate association
0.95 and -0.8 are both strong association
0.10 is weak association
Explanation:
This is the interpreation of the correltaion coefficient:
1) The correlaion coefficient assesses the relationship between two variables in a scatter plot.
2) If the sign of the correlation coefficient is positive means that the two variables trend to grow or decrease in the same sense. This is an uphill line or curve: if variable X grows, variable Y grows, and if variable X decreases variable Y grows.
If the sign of the correlation coefficient is negative means that the two variables go in opposite direction. This is a downhill line or curve.
3) A correlation coefficient of +1 or -1 is a perfect association. The two variables are totally associated.
4) A correlation coefficient less that +1 but greater than 0.7 is a strong association. The same with a coefficite between - 0.7 and -1.
5) A correlation coefficient arroun +0.5 or -0.5 is a moderate association.
6) A correlation coefficient of 0 is a nill association.
7) A correlation coeffiicient between 0 and 0.3 is a weak association. The same when the correlation coefficient is between -3 and 0.
What is the question about ?? Is is asking the degree of the angle between 5 and 4 ?
Answer:
I think the relationship is proportional.

Step-by-step explanation: i know the answer
Answer:
(7.5,3)
Step-by-step explanation:
( (x_1 + x_2)/2, (y_1 + y_2)/2 ) <--Midpoint formula
(5,5) and (10,1) are where you take the x and y values from. The x_1 and y_1 values come from (5,5) and x_2 and y_2 from (10,1).
this gives you ( (5+10)/2, (5+1)/2 )
=( 15/2, 6/2 )
=(15/2, 3)
= or (7.5, 3)
Both bold answers equal the same thing, just depends on if your teacher is asking for it in mixed number form or decimal form.
By the way, I realize it's confusing so the _ is just to show that the following number would be subscript (brainly won't let me show it, so I suggest searching it online if you are still confused..)
Hope this helps!
