Given a right circular cone a plane that intersects the cone (not at the vertex) and is parallel to its edge will always result
in a parabola regardless of the shape of the cone true or false
2 answers:
Answer:
The given statement is a correct statement i.e. TRUE.
Step-by-step explanation:
We know that when a right circular cone is intersected by a plane parallel to it's edge and not passing through the vertex then the cross-section that is formed on this slicing will be a parabola.
Also, a circle is formed when the slicing is done parallel to the base.
This slicing could also be seen with the help of the figure attached to the answer.

Answer:
The 25th percentile is 248.
The 70th percentile is 700.
Step-by-step explanation:
The pth percentile is a data value such that at least p% of the data-set is less-than or equal to this data value and at least (100-p)% of the data-set are more-than or equal to this data value.
Arrange the data set in ascending order as follows:
S = {75 , 157 , 224 , 248 , 271 , 381 , 472 , 495 , 586 , 676 , 700 , 723 , 743 , 767 , 1250}
The formula to compute the position of the pth percentile is:
Compute the 25th percentile as follows:
The 4th observation from the arranged data set is 248 .
Thus, the 25th percentile is 248.
Compute the 70th percentile as follows:
The 11th observation from the arranged data set is 700.
Thus, the 70th percentile is 700.
