Answer:
Step-by-step explanation:
Number of tickets for international flights = 36
Total number of tickets = 95
The probability that a randomly selected airline ticket is for an international flight = 36 / 95 = 0.3789
The probability that a randomly selected airline ticket is for an international flight as a percent rounded to the nearest tenth of a percent = 0.3789 x 100 = 37.9%
% of males surveyed = 0.236 + 0.218 = 0.454 = 45.4%
% of males surveyed who prefer chicken = 0.236 out of 0.454 = 0.236 / 0.454 = 0.5198 = 51.58% = 52.0%

Answer: Option D
D. $108
Step-by-step explanation:
We must calculate the expected cost per patient to use treatment method B.
The expected cost for a discrete random variable x is:

Where
is the cost associated with the probability 
In this case, the random variable x is represented by the cost of each treatment.
For treatment B there is a possibility that antibiotic 2 works, in that case the cost x would be $ 100 and 
There is also the possibility that it does not work, in this case the cost x would be $180 and the probability 
The expected cost is:

Answer:
step 1. for time = 1, distance = 6.
step 2. if time = 4/3 then distance = 6(4/3) = 8
step 3. if distance = 9 then time = 9/6 = 3/2.
Answer:
undefined
Step-by-step explanation:
Horizontal lines have no slope. The line on the graph is vertical, so we can't really tell what slope it is. But there isn't any run and only rise, therefore the slope is "undefined."
