Answer:
A, C, F
Step-by-step explanation:
Definition: The circumcenter is the center of the triangle's circumcircle - the circle that passes through all three of the triangle's vertices. If point H is the circumcenter of the triangle DEF, then the circumcircle passes through its vertices D, E and F (option A is true).
Option B is false, the circumcircle doesn't pass through the points L, M and N. This option is true for inscribed circle, not for circumcircle.
Option C is true, because HD and HE are the radii of the circumcircle.
Option D is false. This option is true for inscribed circle, not for circumcircle.
Option E is false. This option is true for inscribed circle, not for circumcircle.
Option F is true, because both these angles are right angles.
7.5%.
So, <span>the probability that on a given day it will work in the morning is 50% and the probability that it won't is 50%.
If it works in the morning, we're at 50%. Then, it has a 15% chance of failure.
So, it is 50 times 50%, or 7.5%.</span>
5x-y
=5(3)-1
=15-1
=14
Therefore, the answer is 14.
