Answer:
A) 57%
B) 16%
C) 53%
D) 57%
Step-by-step explanation:
Let R1 be students that attend class regularly
R2 be students that don't attend class regularly
A be students that receives A's in class
A) From the question A/R1 =57%
P(A/R1) = 0.57
B) From the question students that receive As that does not attend lectures regularly =16%
C) P(R2) = 1 -0.57 = 0.43
P(A) = P(A/R1) × P(R1) + P(A/R2)×P(R2)
P(A) = (0.57× 0.81) + (0.16×0
43)
P(A) = 0.46 + 0.0688= 0.53
The overall percentage that recieved A's = 53%
D) 57% recieved A's given that they attend class regularly.

Answer:
A, but try the rest of the points!
Step-by-step explanation:
I assume AABC means triangle ABC
Just do the operation to each point. so A is (-6, -7) (x - 2. y - 7) is telling you subtract 2 from -6 and 7 from -7 or in other words it changes from (-6, -7) to (-6 - 2. -7 - 7) = (-8, -14)
Only one answer has that point for A', but you should really really really try the rest.
