Answer:
D) 5 1/6 < 5 13/30 < 5 68/90
Step-by-step explanation:
The best way to determine which value is greater is to find the decimal form of each fraction.
5 1/6 = 5.16...
5 13/30 = 5.43...
5 68/90 = 5.75...

Answer:
<h2>C) r = − 1</h2>
Step-by-step explanation:
In the graph, you can observe that all five points are perfectly lined up on a straight line, which is decreasing, because each points is lower than the previous one.
This situation represents a coefficient of correlation of -1, which means there's a strong negative correlation between variable.
Once again, graphically, this strong negative correlation can be deduct from the behaviour of the data, which is clearly decreasing with a straight line behaviour. In other words, the line that best fits is almost unique.
Therefore, the right answer is C.
