Answer:
The ranking of the top three teams could occur in 720 ways.
Step-by-step explanation:
The order in which the teams are ranked is important, that is, for example, Oilers, Flames and Canucks is a different outcome of Oilers, Canucks and Flames. This means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In how many ways could the ranking of the top three teams occur?
Three teams from a set of 10. So
The ranking of the top three teams could occur in 720 ways.
Maria will have 6 dresses altogether if you add them up. Maria only has 1 blue dress, which means you will have a 1/6 chance of her wearing a blue dress.
1/6 = 0.1666 = 16.666%
Slope formula : (y2 - y1) / (x2 - x1)
set 1 : (12,7)....x1 = 12 and y1 = 7
set 2 : (9,6)....x2 = 9 and y2 = 6
now we sub
slope = (6 - 7) / (9 - 12) = -1/-3 = 1/3 <==
