Remember that
If an ordered pair is on the graph of the given function, then the ordered pair must satisfy the given function
Verify each option
N 1
(0,1)
x=0, y=1
Is not true, because the log of zero is undefined
N 2
(1,1/2)
x=1, y=1/2
Is not true, because the log of 1 is zero
N 3
(1/2,1)
Is true
therefore
<h2>The answer is (1/2,1)</h2>
<h3>The probability of student passing the quiz with at least 50% of the questions correct is 0.05457.</h3>
Step-by-step explanation:
Here, the total number of T/F question = 10
The minimum answers needed correctly answered = 8
So, student needs to answer at least 8 questions correctly.
Here, the possibility of answering a question correctly = = p = 0.5
Also, the possibility of answering a question wrong = = q = 0.5
Now, to pass he needs to answer 8 or more ( 8 , 9 or 10) answers correctly.
P(answering 8 correct answer) =
P(answering 9 correct answer) =
P(answering 10 correct answer) =
So, the total Probability = P(8) + P(9) + P(10)
= (0.0439) + (0.0097) + (0.00097)
= 0.05457
Hence, the probability that the student passes the quiz with at least 8 of the questions correct is 0.05457.
