Answer:
A, C, and E are the answers
Step-by-step explanation:
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.

Answer:
Equation:
17 + p = 46
His teammates scored 29 points
Step-by-step explanation:
We know that Mark scored 17 points and that the entire team scored 46.
Mark's 17 points added to the team's p points will give us a total of 46 points
p = points of his teammates
17 + p = 46
if we want to know how many points his teammates scored we simply have to clear p and solve
17 + p = 46
p = 46 - 17
p = 29
his teammates scored 29 points
Answer:
0.8749
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

The probability that Z is less than 1.15 is:
This is the pvalue of Z = 1.15, which is 0.8749.
