Answer:
The probability is 0.0144
Step-by-step explanation:
The probability that x people show up follows a binomial distribution, so it is equal to:
Where n is the number of booked people and p is the probability that a person shows up. Then, the probability that x people show up is:
So, the probability that the number of people who show up will exceed the capacity of the plane is:
P(x>73) = P(74) + P(75)
Where P(74) and P(75) are calculated as:
Finally, P(x>73) is:
P(x>73) = 0.0125 + 0.0019 = 0.0144
A.
earnings=bonus+pay
pay=pay per hour times number of hours
h=number of hours
9.5=pay per hour
pay=9.5h
bonus=60
earnings=9.5h+60
at least 460
greater than or equal to 460
9.5h+60<span>></span>460
B. solve for h
9.5h+60<u>></u>460
subtract 60
9.5h<u>></u>400
divide oth sides by 9.5
h<u>></u>42.1
at least 42.1 hour (about 42 hours and 6 minutes, if the job is rounding, then say 43 hours)
A. 9.5h+60<u>></u>460
B. 42.1 hours
Answer:
-4x=4
Step-by-step explanation:
-4x+7=11 subtract 7 add to the 11 answer-4x=4
Since xy = a (a is a constant)
a = 8*1.55 = 12.4
so -0.62x = 12.4
-> x= 20
