Paul observes that AB=AC and concludes that AB and AC must be tangent to the circle. What is wrong with Paul's reasoning?
1 answer:
The complete question in the attached figure
we know that
the triangle AOB is congruent with triangle AOC
because
AB=AC
OB=OC-----> the radius of the circle
<span>The OB side is common
</span>but
<span>there is no additional information that allows me to calculate the OBA angle to determine if it is a right angle
</span>
therefore
the answer is the option
<span>C. There is no indication that AB and AC are perpendicular to the radii at the points of intersection with the circle.</span>

Answer:
The correct answer is 0.15
Step-by-step explanation:
According to the given scenario, the probability is as follows:
X Bin (n,p)
Here
n = 8
p = 0.20 or 20%
Now this is a binomial probability distribution
= 0.15
Hence, the correct answer is 0.15
