Answer: Expected value would be 
Step-by-step explanation:
Since we have given that
Number of multiple choice question = 4
Number of true false questions = 2
Number of points for each multiple choice question = 3
Number of points for each true false question = 1
Number of choices in multiple choice = 5
Probability of getting correct answer in multiple choice question = 
Probability of getting correct answer in true false question = 
Expected value of the student's score on the test would be

Hence, expected value would be 
Answer:
<h2>-5</h2>

Answer:
x = 4(y + 6)/5
Step-by-step explanation:
2x - y = (3/4)x + 6
2x - (3/4)x = y + 6
(8x - 3x)/4 = y + 6
5x/4 = y + 6
5x = 4(y + 6)
5x = 4y + 24
x = (4y + 24)/5
Therefore, x = 4(y + 6)/5

Hope this helps. Have a good day/night!
(C is a possibility but doubt it's an answer)
The missing length x is 99 m.
Solution:
Given polygons are similar.
<em>If two triangles are similar, then the corresponding sides are in proportion.</em>

Multiply by 22 on both sides, we get


⇒ 9 × 11 = x
⇒ 99 = x
Switch the sides.
⇒ x = 99
The missing length x is 99 m.
