Yintercept is the point where the line crosses the y axis and where x=0
(x,y)
yintercept at y=b is
(0,b)
Answer:
99.7%
Step-by-step explanation:
Mean number of passengers (μ) = 180 passengers
Standard deviation (σ) = 20 passengers
The number of standard deviation from the mean for the lower and upper bounds of the 120 to 240 passengers intervals are:

Therefore, all of the data is within 3 standard deviations from the mean. According to the empirical rule, 99.7% of the data is within 3 standard deviations from the mean. Therefore, we can assert with a 99.7% probability that there will be between 120 and 240 passengers.
Answer:
0
Step-by-step explanation:
2a(b−c)+b(2c−2a)+4c(0.5a−0.5b)
To simplify this we need to remove the parenthesis
Distribute 2a, b and 4c inside the parenthesis
2ab -2ac + 2bc - 2ab + 2ac - 2bc
now we combine like terms'
2ab - 2ab becomes 0
-2ac +2ac becomes 0
+2bc - 2bc becomes 0
So final answer is 0
