Answer:
a)
The correlation coefficient for this case is very near to 1 so then we can ensure that we have linear correlation between the two variables
b)
Now we can find the means for x and y like this:
So the line would be given by:
Step-by-step explanation:
Part a
The correlation coeffcient is given by this formula:
For our case we have this:
n=4
The correlation coefficient for this case is very near to 1 so then we can ensure that we have linear correlation between the two variables
Part b
Where:
With these we can find the sums:
And the slope would be:
Now we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
38. The nearest whole number to 38.49 is 38 because at .5 you begin rounding up to the nearest whole number.

Answer:
$19.99 for each cartridge.
Step-by-step explanation:
For this problem, we are finding the cost of the three printer cartridges. Since the problem says that the tax was 5.95, we can subtract that from 90.91.
90.91-5.95=
84.96
Next, since we know that the software package was 24.99, we can subtract that from 84.96.
84.96-24.99=
59.97
Finally, since there are three printer cartridges, we can divide 59.97 by 3, and get our answer.
59.97/3=
19.99
Each printer cartridge would cost $19.99.
Hope this helps and have a good day! :D
