Answer:
It would most likely be 0.9.
Step-by-step explanation:
The correlation coefficient ranges from -1 to 1 and is dependent on how strong the correlation is between the points. It cannot be 1.2 as it is above one and it cannot be 1 because all the points do not line up on the line of best fit. However, most do, so we can assume that there a strong positive linear relationship which means 0.9 would be the correct answer. The close r gets to zero means the less of a correlation there is. The line of best fit isn't negative so it cannot be -0.23 and it has a strongly positive correlation, not a weak one so it isn't 0.13.

Yes, what?
Answer:
x = 16
Step-by-step explanation:
The two marked angles are supplementary:
(7x -2) +(4x +6) = 180
11x +4 = 180
11x = 176
x = 176/11 = 16
The value of x is 16.
_____
<em>Additional comment</em>
The angle on the left is 110°; the one on the right is 70°, so that answer checks.
These marked angles are called "consecutive exterior" angles. Just as "consecutive interior" angles are supplementary, so are consecutive exterior angles.
Essentially, all of the obtuse angles are congruent, as are all of the acute angles. The obtuse angles are supplementary to the acute angles.
Answer:
$3.5
Step-by-step explanation:
We have been given that Tyler baked 702 cookies. He sold them in boxes of 18.
First of all we will find the number of boxes of cookies by dividing 702 by 18.
We are told that after selling all the boxes of cookies for the same amount each he earned $136.50. To find the cost of each box we will divide 136.50 by 39.
Therefore, the cost of one box of cookies is $3.5.
Answer:
The exact solution is
And the approximation to three decimal places is:
x = 0.363
Step-by-step explanation:
Here we have the equation:
Now we can remember a property of the natural logarithm function:
Ln(a^n) = n*Ln(a)
Now we can apply the Ln( ) function to both sides of that equation to get:
Then we get:
Solving that for x we get:
So the exact solution is:
And the approximation to three decimal places is:
x = 0.363
