6: a production facility employs 18 workers on the day shift, 11 workers on the swing shift, and 10 workers on the
graveyard shift. a quality control consultant is to randomly select 7 of these workers for in-depth interviews.
(a) what is the probability that all 7. selected workers will be from the same shift?
(b) what is the probability that at least two different shifts will be represented among the selected workers?
(c) what is the probability that exactly 3 of the workers in the sample come from the day shift?

can some me with part c plzzz

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.
