Answer:
E
Step-by-step explanation:
The problem says that triangle BDC lies in the plane k, which means that whatever angle is formed by another point beyond this plane with any of the three segments that form BDC (BD, DC, and BC) is the same as the angle formed by the line connecting the point and the plane.
Here, we're given that AD⊥DC, which means AD forms a 90° angle with DC. Then, since DC is already on the plane, we already know for sure that AD is definitely perpendicular to plane k.
Thus, the answer is E (none of these).

If she continues to throw darts 75 more times, she could predict to hit the
</h2><h2>
bull's-eye 15 times.</h2>
Step-by-step explanation:
Shay found that she hit the bull's-eye when throwing darts
times =
.
In five times, she will hit the dart once.
If she continues to throw darts 75 more times,
the probability that she will hit the bull's eye =
(75) = 15 times.
If she continues to throw darts 75 more times, she could predict to hit the
bull's-eye 15 times.
Students with D's / total students : 3 / (7 + 9 + 11 + 3 + 2) =
3 / 32 = 0.0937...to turn to a percent, multiply by 100 = 9.375....rounded =
9.4% <== ur probability
