Answer:
x=0
Step-by-step explanation:
substitute y=0
0= -x^2
then swap the sides
-x^2=0 ,
change the signs
x^2=0
set the base equal to 0
x=0

Answer:
The first one. It costs less.
Step-by-step explanation:
Divide 3.29 by 32, then divide 2.59 by 24. Then round the two answers. The first one should cost less.
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.
