Answer:
5/12
Step-by-step explanation:
15 students went to hear the doctor speak and 21 students went to other sessions
How many students are there? 15 + 21 = 36 students
Therefore, the probability to randomly select a student that went to hear the doctor is , then simplifying it by 3 is .
If we want to express it in percentage it would be 41.6%
The correct option is (A) Yes they are similar.
Explanation:
One quadrilateral (the red one) is the scaled version of the other quadrilateral (the blue one).
All you need is to reflect and dilate the blue one to make the red one.
Hence they are similar to each other. The question is asking about similarity; therefore the correct option is (A) Yes they are similar.
The answer would be 75 using the formula v=1/2(a)(c)(h)
3x^2 + 2x - 6 if x = -2
=3(-2)^2 + 2(-2) - 6
=12 - 4 - 6
= 2
5x^2 + 6x - 2 if x = -2
=5(-2)^2 + 6(-2) - 2
=20 - 12 - 2
= 6
-2x^3 + 2x^2 if x = 2
= -2(2)^3 + 2(2)^2
= -16 + 8
= -8
