12. The table shows the heights and the widths of several rectangles.
Height 82 140 42 64 20 184
(in.)
Length 42 50 64 24 32 90
(in.)
What does the correlation coefficient for the
data indicate about the strength of the linear
association between the height and the
length of these rectangles?
a. Weak positive correlation
b. Strong positive correlation
c. Weak negative correlation
d. Strong negative correlation

what is the question here

step-by-step explanation:

yes. we do proportions in probabilities.

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.
