Answer:
So then the correlation coefficient would be r =0.8465
And the best options would be:
(D) 0.847
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:
Solution to the problem
Data given:
X: 8 10 7 13 7 9 9 10 11 8
Y: 60 75 55 83 61 73 80 85 85 66
For our case we have this:
n=10
And if we replace into the formula we got:
So then the correlation coefficient would be r =0.8465
And the best options would be:
(D) 0.847
Answer:
1) 4T+T=125
2) Rhonda drove 25 miles
and Jamie drove 100 miles
Step-by-step explanation:
1) Rhonda drove = T
Jamie drove = 4T
4T+T=125
2) 5T=125
T=125/5
T=25
So Rhonda drove T = 25
And Jamie drove 4T = 100
