Answer:
216
Step-by-step explanation:
6*6=36
36*6=216
Answer:
n=6
So then the correlation coefficient would be r =0.913
And as we can see the value for r is very high and near to 1. so the correct option for this case would be:
C. There is a positive correlation between the heights of men and women.
Step-by-step explanation:
Previous concepts
The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.
And in order to calculate the correlation coefficient we can use this formula:
We have the following data:
Women (X): 66 64 66 65 70 65
Men(Y): 72 68 70 68 74 69
We have quantitative data so no makes sense say that we have categorical data.
For our case we have this:
n=6
So then the correlation coefficient would be r =0.913
And as we can see the value for r is very high and near to 1. so the correct option for this case would be:
C. There is a positive correlation between the heights of men and women.
Answer:
2/3
Step-by-step explanation:
I hope it helped you
Multiply the whole numbers as usual. then find the gcf and divide for how many times the denominator can go into the gcf. gcf for 1/5 and 2/3 is 15 but Idk how to deal with the numerator.
(7+x)+x=15
I did trial and error to get x=4.
