Triangle HKJ is inscribed in the circle as shown. If the triangle is a right triangle, what can you conclude about HJ?
1 answer:
Answer:
HJ is diameter.
Step-by-step explanation:
Given Triangle HKJ is inscribed in the circle. we have to conclude about HJ if the triangle is a right triangle.
All the three sides are chord of the circle.
As given HKJ is right angled triangle i.e∠HKJ=90° and angle subtended by diameter in the semicircle is 90° implies HJ is diameter because if the HJ moves towards the angle then the given angle becomes acute and if moves away from the angle then the angle becomes obtuse which contradict the given information.
hence, the only possibility about the line HJ is that it is a diameter.

Answer:
$116800
Step-by-step explanation:
Step one:
given
principal= $40,000
rate= 5.5%
time = 20 years
Step two:
the final amount is expressed as
substitute
$116800
We find the probability of intersection using the inclusion/exclusion principle:
By definition of conditional probability,
For
in which case we have
Or, to establish independence another way, in terms of conditional probability, we must have
which is also true.
