Answer:
B
Step-by-step explanation:
since the strongest correlation is either 1 or negative 1, and weakest is closer to 0,
now, lets order from weakest to strongest:
-0.52,0.65, 0.8, -0.87
Since -0.87 is closest to negative one than others to -1 or 1, it has the strongest linear relationship

Answer:
Your wrong, it’s B.
X axis = Number of Bottles of water sold
Y axis = Number of dollars collected
So, (x,y)
That means, (Number of Bottles of water sold,Number of dollars collected)
Finally, (10,20) means he sold 10 bottles of water for $20.
Hope that helped!
Step-by-step explanation:
Two consecutive odd integers are and , for some integer .
Their product is .
Twice their sum is
Since the product is 1 less than twice the sum, we have
So, we have
If , the integers are 3 and 5
If , the integers are -1 and 1.
In both cases, in fact, we have:
- 3*5 = 15, which is one less than 2(3+5)=2*8=16
- (-1)*1=-1, which is one less than 2(-1+1)=0
