15-9 = 6
6-6 = 0
If you were to check your work, you would get 51. What did I do wrong???
Answer: L = 50 while W = 17
Step-by-step explanation:
So, n=42
L = n + 8
L = 42 +8
L = 50
W = n/2 - 4
W = 42/2 - 4
W = 21 - 4
W = 17
Delayed 7.5% 17.5%
On Time 42.5% 32.5%
Given these percentages, during bad weather, is it more likely that your flight will be delayed or on time? How much more likely?
Answer:
More likely: on time
By 0.3 or 30%
Step-by-step explanation:
Bad weather is column 2
P(delayed) = 17.5/(17.5+32.5)
= 17.5/50 = 0.35
P(on time) = 32.5/(17.5+32.5)
= 32.5/50 = 0.65
0.65 - 0.35 = 0.3
