One hundred and fifty people were surveyed and asked if they believed in UFOs, ghosts and bigfoot43 believed in UFOs44 believed in ghosts25 believed in bigfoot10 believed in UFOs and ghosts8 believed in ghosts and bigfoot5 believed in UFOs and bigfoot2 believed in all three. Q: Using Venn Diagram find how many people surveyed believed in at least one of these things.

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.
