Answer: (c) when the plane makes a narrow angle with the base.
Step-by-step explanation: The prism has a base which is a 9 sided polygon. If the intersecting plane is parallel to the base, then the intersection is either null or the base itself. So, option (a) is incorrect. Options (b) is also not correct because in that case also, the intersection is a polygon having number of sides less than 10 (see attached fig.). The only remaining and correct answer is (c).
Thus, the correct option is (c).
The last statement "Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1." is the correct statement.
A few fundamental principles apply to density curves:
- A density curve's area beneath it represents probability.
- A density curve's area under it equals one.
- Base x height in a uniform density curve equals one.
- The likelihood that x = a will never occur.
- The likelihood that x < a is the same as that of x ≤ a.
Following the rules above, we can see from graph B that the curve is above the horizontal axis. That shows that the probabilities are positive which is a necessity. Moreover, the area under the curve must also be 1. That is also satisfied.
Hence, the last statement "Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1." is the correct statement.
