A professor has noticed that, even though attendance is not a component of the final grade for the class, students that attend regularly generally get better grades. In fact, 54% of those who come to class on a regular basis receive A's. Only 8% who do not attend regularly get A's. The overall (marginal) attendance rate is 84%. Based on this class profile find the following: a. The percent who get A's given that they attend class regularly.
b. The percent who get A's given that they do not attend class regularly.
c. The overall percent of the students who get A's in the class
d. The percent who attend class regularly given that they get A's

c. (3,2,6) is the answer.

b if for most of the graph

d if y intercept

step-by-step explanation:

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
