Answer:
138 pounds
Step-by-step explanation:
Let the required weight of the patient be x pounds.
We have that,
156 milligrams of medicine is required for a patient weighing 104 pounds.
Then, 207 milligrams of medicine will be required for a patient having weight as shown below,
Weight of the patient =
i.e. x =
i.e. x =
Hence, the patient needing 207 milligrams of medicine will have the weight 138 pounds.
Answer:
a. The multiplication of these probabilities is justified because the inspections are isolated or don't have the same goal. For instance p1, would mean that not all the planes are checked, p2 that not all the parts in the plane are checked, and p3, that even if the the part where the crack could be inspected, people checking it could not notice it or it could be not identified easily.
b. As the events are independent and there are only two possible answers (detect the plane or not), a binomial distribution could be applied, therefore:
p=0.9*0.8*.5=36 (probability of detecting the crack)
n=3 (number of possibilities, in this case number of planes)
The probability in a binomial formula is given by
Considering that the only possibility that is not being asked is the one of not detecting any crack which would mean x=0, then, we could find the probability as
=1-
Probability is then 0.737856
