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:
I believe the answer would be true.

Hey there! :)
Answer:
Choice C: x + 8 = 3x.
Step-by-step explanation:
Solve this question by simplifying each answer choice:
a) 4x = 20
Divide both sides by 4:
4x/4 = 20/4
x = 5. This is incorrect.
b) x/2 = 8
Multiply both sides by 2:
x = 16. This is incorrect.
c) x + 8 = 3x
Subtract x from both sides:
8 = 2x
Divide 2 from both sides:
x = 4. This is correct.
d) x = x+5 /2
Multiply both sides by 2:
2x = x + 5
Subtract x from both sides:
x = 5. This is incorrect.
Therefore, choice C is the correct answer.
X1 + X2 + X3 <27 for all Xi> 0
X1 + X2 + X3 <27 for all Xi> 0, X2 >/ 5
