Answer:
y-intercept=1
Step-by-step explanation:
the y-intercept of a graph is the point where the graph crosses the y-axis.
now that we know what y-intercept is, we also know how to find it- and in your case, the y-intercept is 1 because that is where the line hits a 'perfect point' on the y-axis
good luck :)
i hope this helps
have a nice day !!

Answer:
a) 0.97605 = 97.605% probability that the process will signal.
b) 0.2076 = 20.76% probability that microaerophiles are present.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
a. What is the probability that the process will signal?
It signals in these following moments:
97.8% of 31%(contains obligate anaerobes).
98.1% of 27%(contains facultative anaerobes).
96.5% of 21%(contains microaerophiles).
99.2% of 12%(contains nanaerobes).
95.9% of 9%(contains aerotolerant). So
0.97605 = 97.605% probability that the process will signal.
b. If the test signals, what is the probability thatmicroaerophiles are present?
Event A: Test signals
Event B: Contains microaerophiles
0.97605 = 97.605% probability that the process will signal.
This means that
Intersection of events A and B:
Signals containing microaerophiles, which is 96.5% of 21%. So
The probability that microaerophiles are present is:
0.2076 = 20.76% probability that microaerophiles are present.
