Answer:
can you show the picture
Step-by-step explanation:
The answer is seven because if you divide 49 by 7 it equals 7.
If the number of the edges of the polyhedron is 14 and the vertices are 9. Then the number of the faces of the polyhedron is 7.
<h3>What is a
polyhedron?</h3>
A polyhedron is a solid made composed of polygons in three dimensions. It has vertices, flat faces, and straight edges.
We know the Euler's formula
F + V - E = 2,
where, F = number of faces, V = number of vertices, and E = number of edges
Edges: 14
Vertices: 9
F + 9 - 14 = 2
F = 14 + 2 - 9
F = 16 - 9
F = 7
Then the number of the faces of the polyhedron is 7.

f(x)=-3x^2-1
f(-2)= -3(-2)²-1=-3·4-1= - 13
The probability is the ratio of the favorable event to the total number of events. The P(C|Y) is 0.5. Then the correct option is B.
<h3>What is probability?</h3>
Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.
According to the problem, the table is made
X Y Z Total
A 32 10 28 70
B 6 5 25 36
C 18 15 7 40
Total 56 30 60 146
Then the probability of will be
The P(C|Y) is 0.5. Then the correct option is B.
