Answer:
a. fly = 5.7
b. fly = 7.5
Step-by-step explanation:
a.
hoist/fly = 1 / 1.9
The new hoist is 3. To get this you have to multiply 1 by 3. That means you have to multiply 1.9 by 3 too.
1.9 * 3 = 5.7
b.
hoist/fly = 3/5 (this is the new ratio)
4.5 / 3 = 1.5
5 * 1.5 = 7.5
2 14/16. .........................That's the answer
The probability that a random alcoholic can kick the habit without professional help is 0.273 .
<h3>What is Probability ?</h3>
Probability is the study of likeliness of an event to happen.
It has a range of 0 to 1 , where 0 indicates uncertainty and 1 indicates certainty.
It is given that
The alcoholics that need professional help to stop drinking is 72.7 %
Therefore the probability of this is 72.7 /100 = 0.727
The probability that they will not need professional help is given by
q = 1 - p
q = 1 -0.727
q = 0.273
Therefore the probability that a random alcoholic can kick the habit without professional help is 0.273 .
