Answer:
1 in 120 or 0.83%
Step-by-step explanation:
There are 5 possible winners to be called first, 4 possible winners are then left to be called second, 3 to be called third, 2 to be called fourth and the final winner is left to be called last. Therefore, the number of possible ways to arrange the winners is:
There is only one possible order for which the winners are called in order by the age from youngest to oldest. Therefore, the probability of this happening is 1 in 120 or 0.83%.
The answer would be C corresponding
50° is the answer since the the circumscribed angle is 1/2 of the arc on the opp side
For this case we have the following equations:
y = 60x + 40
y = 50x + 80
Equaling both equations we have:
60x + 40 = 50x + 80
From here, we clear the value of x:
60x - 50x = 80 - 40
10x = 40
x = 40/10
x = 4 weeks
Substituting x = 4 in any of the equations we have:
y = 60 (4) + 40
y = 240 + 40
y = 280 $
Answer:
$ 280 4 weeks
