Answer: A (edg2020)
Answer:
87.9
Step-by-step explanation:
Use a calculator or table to find the z-score that corresponds to 25%.
P(Z < z) = 0.25
z = -0.675
Now find the value that corresponds to that z score.
z = (x − μ) / σ
-0.675 = (x − 101.3) / 19.9
x = 87.9
The next statements are are;
Statement Reason
Segment ≅ Segment CPCTC
≅ and ≅ , therefore;
ABCD is a parallelogram Parallelogram side theorem
Segment ≅ Segment by Congruent Parts of Congruent Triangles are Congruent (CPCTC)
Given that ≅ and we have that ≅ , we get;
The parallelogram side theorem states that a quadrilateral is a parallelogram if it has two pairs or sets of congruent opposite sides.
