Answer:
C.
Step-by-step explanation:
We have been given a circle. We are asked to find the name of central angle that corresponds to arc GEH.
We can see that center of the circle is at point Q. We can also see that arc GEH is the major arc of circle Q.
Therefore, the central angle that subtends to arc GEH would be and option C is the correct choice.

Answer:
(B) 18.
Step-by-step explanation:
We are asked to find the perimeter of a quadrilateral with vertices at (-1, 4), (7,4), (7,5), and (-1. 5).
First of all, we will draw vertices of quadrilateral on coordinate plane and connect the vertices as shown in the attached photo.
We can see that our quadrilateral is a parallelogram, whose parallel sides are equal.
Therefore, the perimeter of the given quadrilateral is 18 units.
Answer
given,
thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters.
X = U[0.95,1.05] 0.95≤ x ≤ 1.05
the cumulative distribution function of flange
F(x) = P{X≤ x}=
=
b) P(X>1.02)= 1 - P(X≤1.02)
=
= 0.3
c) The thickness greater than 0.96 exceeded by 90% of the flanges.
d) mean =
= 1
variance =
= 0.000833
