Answer:
8.3
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
Circumference of the circle = 52 cm
<em><u>Therefore</u></em><em><u> </u></em><em><u>,</u></em>
<em>By</em><em> </em><em>the</em><em> </em><em>problem</em><em>, </em>
=> r = 8.2802547771
<em>Rounded</em><em> </em><em>to</em><em> </em><em>nearest</em><em> </em><em>tenth</em><em>,</em>
=> <em><u>r = 8.3 (Ans)</u></em>
60 x .055 = $3.3

Answer:no
Step-by-step explanation:
Answer:
So then the correlation coefficient would be r =0.98726
And the determination coeffcient would be:
And that means that the a linear model will explain about 97.5% of the variability in the data. So for this case we can conclude that we have a strong linear relationship.
Step-by-step explanation:
Data given
col1 x 20 40 60 80
col2 y 0.24 1.10 1.71 2.12
Solution to the problem
We can find the correlation coefficient we can use this formula:
For our case we have this:
n=4
So then the correlation coefficient would be r =0.98726
And the determination coeffcient would be:
And that means that the a linear model will explain about 97.5% of the variability in the data. So for this case we can conclude that we have a strong linear relationship.
