Answer:
Option A
Step-by-step explanation:
Given that you want to do a psychological experiment. On any given day, there is a 30% chance that your participant won’t show up. In addition, there is a 10% chance that the stimulus presentation software won’t work. There is also a 5% chance that there is a problem with saving the data and a 2% chance that there are other problems like experimenter error.
Also given that each of the above four is independent.
Successful experiment can be done only if participant shows up (0.70), stimulus software works (0.90) , Saving the data (0.95) and no other problem (0.98)
Put to gether these independent events to use prob for all is product of probabilities
we have
the probability that you will be able to do a successful experiment (be able to collect useful data) on any given day
=
=0.59

Answer:
11 music lessons.
Step-by-step explanation:
We know that membership costs $165 and members pay $25 per music lesson.
So, we can write the following expression:
The 165 represents the one-time membership fee and the 25m represents the cost for m music lessons.
We know that non-members pay no membership fee but their cost per lesson is $40. So:
Represents the cost for non-members for m music lessons.
We want to find how many music lessons would have to be taken for the cost to be the same for both members and non-members. So, we can set the expressions equal to each other:
And solve for m. Let's subtract 25m from both sides:
Now, divide both sides by 15:
So, at the 11th music lesson, members and non-members will pay the same.
Further Notes:
This means that if a person would only like to take 10 or less lessons, the non-membership is best because there is no initial fee.
However, if a person would like to take 12 or more lessons, than the membership is best because the membership has a lower cost per lesson than the non-membership.
And we're done!
