Given : 2D + 1L = 100,
And D + L = 70
This is a simultaneous equation can be solved as follows
2D + L = 100
- D - L = -70
————————————-
D - 0 = 30
i.e D (number of dudes) = 30
Therefore, since we already know the fraternity sold 70 tickets in total,
70 -30 = 40 (the number of ladies attended)
You have to use the distance formula which is:
Distance = √(x2 - x1)^2 + (y2 - y1)^2
Using the coordinates given.
D = √(4 - (-2)^2 + (1 - 4)^2
D = √(6)^2 + (-3)^2
D = √36 + 9
D = √45
D = √9 × 5
D = 3√5
The probability that it rains everyday is 0.000729
Forecast for rain = 30%
Since it's a 6 days vacation, the probability that it rains every day will be:
= 30% × 30% × 30% × 30% × 30% × 30%
= 0.3 × 0.3 × 0.3 × 0.3 × 0.3 × 0.3
= 0.000729
Therefore, the probability is 0.000729
