The table shows the number of championships won by swim teams and ice-skating teams among the three divisions organized by age groups.
swimming team (s) ice-skating team (i)
junior (j) 9 8
junior high (h) 5 7
senior (r) 8 6
total 22 21
if the ice-skating team is the winner, the probability that the junior high team wins is

  1/3

Step-by-step explanation:

7 Jr High teams won ice-skating out of 21 ice-skating winners. If an ice-skating winner is chosen at random, the probability it is a Jr High team is ...

  7/21 = 1/3

10

step-by-step explanation:

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.
