How could the relationship of the data be classified?

a. a fairly strong positive correlation
b. a fairly weak positive correlation
c. a fairly strong negative correlation
d. a fairly weak negative correlation

That would be a fairly weak positive correlation.

Step-by-step explanation:

If you start in the origin and go up, the correlation is positive.

This would be fairly weak because the points are pretty scattered. If it were strong, you could almost draw the line of best fit by yourself. Here you can't.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
