Answer:
She can determine that while there is an association between the variables, there is no correlation, and she cannot determine causation.
Step-by-step explanation:
Since there is an arch shape to her graph, we know that as one variable changes, the other changes in the same manner. This means there is an association between the variables.
However, since the graph is not linear, there is no correlation between the variables. Since there is no correlation, we cannot determine causation.

The dimensions of the rectangle are length 156 m and a width of 65m, and a perimeter P = 442m
<h3>How to find the dimensions of the rectangle?</h3>
For a rectangle of length L and width W, the diagonal is:

Here we know that the diagonal is 169m.
And the ratio of the length to the width is 12:5
This means that:
W = (5/12)*L
Replacing all that in the diagonal equation:

So the length is 156 meters, and the width is:
W = (5/12)*156 m = 65m
Finally, the perimeter is:
P = 2*(L + W) = 2*(156 m + 65m) = 442m

Answer:
The repeating decimal cost
a) As a fraction = $
b) As a mixed number = $ 
Step-by-step explanation:
The cost of making a computer component
= $3.161616
= $ 3 + 0.161616
Looking at the repeating decimal it is in 6 decimal places, hence to convert it to a fraction,
0.161616/ 1000000 × 1000000
= 161616/1000000
Therefore, the cost of making the computer component =
$3 + $161616/1000000
Step 1
We convert to a fraction
$3 + $161616/1000000
We find the LCM = 1000000
($3 × 1000000)+ ($161616× 1)/1000000
3000000 + 161616/1000000
= $ (3161616/1000000)
As a Mixed number =
