Two math questions plz
1 answer:
we know that
<u>The correlation coefficient</u> is a measure of linear association between two variables. Values of the correlation coefficient are always between −1 and +1.
Using a mathematical tool-------> Excel software
Find the correlation coefficient
see the attached table N 1 and N 2
the answer is
Part 1) The correlation coefficient of the data is 0.02
Part 2) The correlation coefficient of the data is 0.98

Answer:
Option c.
No damping
Step-by-step explanation:
We can easily solve this question by using a graphing calculator or any plotting tool.
The function is
f(x) = (√11)*cos(3.7x)
Which can be seen in the picture below
We can notice that f(x) is a cosine with maximum amplitude of (√11). Neither this factor nor the multiplication of x by 3.7 serve as a damping factor since they are constants.
f(x) does not present any dampening
