I believe the answer is the first option
(Correct me if I’m wrong in comments)
Answer: 80
Reasoning: A polyhedron can have 30 edges. If this polyhedron has 120 it has 4 times the “other” one. If it has 30 edges it will have 20 vertices, meaning 20*4=80 vertices
Given:
Circle with center P.
To find:
Which statement is true.
Solution:
In the circle P,
- PT is a radius of the circle P.
- VU is a diameter of the circle P.
- SR is a secant of the circle P.
- NQ is a tangent line and Q is a point of tangeny of circle P.
Option A:
N is a point of tangency on circle P.
It is is not true because Q is a point of tangency of circle P.
Option B:
PT is a secant of circle P.
It is not true because PT is a radius of the circle P.
Option C:
SR is a secant of circle P.
It is true by the above bulleted points.
Option D:
VU is a tangent of circle P.
It is not true because VU is a diameter of the circle P.
Therefore SR is a secant of circle P is a true statement.
Answer:
Mean: μ = 158.4
Standard deviation σ = 3.3941
Step-by-step explanation:
The mean number of packages produced per worker in an 8-hour day is the product of the mean number of packages produced per hour multiplied by the total number of hours:
The standard deviation for 158.4 packages produced in an 8-hour period is the product of the standard deviation per hour by the square root of the total number of hours:
