Step-by-step explanation:
5/7 • 4/5 is 2/3 so Sarah ran 2/3 around the track.
It is 7. None of the other ones fit at all
Answer:
C)
Step-by-step explanation:
- π can be added to π to get a rational number
π + (-π) = 0
0 is a rational number
The best estimate for this correlation would be B) 0.9.
We can see that the number is constantly going up, which would throw out the D answer.
We can also see that for every time the x goes up 1, the y goes up a little less than one. We can see that in the ordered pairs that exist on the graph such as (3, 2), (8, 6) and (2.1, 1.9).
Since the y values are just lower than the x, the correlation would be just under one. Therefore, 0.9 is an accurate estimation.
