The sample is 200 randomly selected students.
The following things should be considered:
- Let us assume the no of siblings for each student be x.
- Now for determining the mean no of siblings she choose 200 students.
So, here the sample should be 200 randomly selected students.
Therefore the other options should be incorrect.
Thus we can conclude that the sample is 200 randomly selected students.

Well it would be (x+3)(x+3)
using the FOIL method you end up with:
x^2 + 6x + 9
:D
You forgot to post the function
If the angle G is moved to a different spot in the circle the angle FGH and angle FEH in the cyclic quadrilateral will change to make it supplementary.
<h3>How to find angles of cyclic quadrilateral?</h3>
A cyclic quadrilateral is inscribed in a circle. It has all its vertices on the circumference of the circle.
Opposite angles in a cyclic quadrilateral are supplementary angles. That means they add up to 180 degrees.
Therefore,
∠F + ∠H = 180°
∠G + ∠E = 180°
Hence, if we moved ∠G to a different spot on the circle, angle FGH would change but angle FEH will also change to make the two opposite angles supplementary.
Therefore, Felix was wrong.

Answer:
1080°
Step-by-step explanation:
formula to find the sum of interior angles of a polygon is (n-2)×180
octagon has 8 sides so n=8
(8-2)×180
6×180
=1080°
