At the avonlea country club, .73 of the members play bridge and swim, and .82 play bridge. if a member is selected at random, find the probability that the member swims, given that the member plays bridge.

0.89.

Step-by-step explanation:

We have been given that at the Avonlea country club, 0.73 of the members play bridge and swim, and 0.82 play bridge.

To find the probability for our given problem we will use conditional probability formula.

, where,

= The probability of B given A.

Upon substituting our given values in above formula we will get,

Therefore, the probability that the member swims, given that the member plays bridge is 0.89.

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.
