To get the answer we can use proportion.
30----------100%
12-----------x
Cross multiply now
30x=12*100%
30x=1200% /:30 (divide both sides by 30)
x=40% - it's the percentage of cars which finished the race.
100%-40%=60% - it's the answer

Step-by-step explanation:
The events are independent because you are selecting the students randomly and how much they like rap music does not depend on the results on the other students.

In this experiment there are 10 possible results for each event, therefore the distribution inst binomial. The correct answer therefore is C.
Answer:
<h3>
x = 14, x = –
8 </h3>
Step-by-step explanation:
|x - 3| = 11
(x – 3) = 11 ∨ –(x – 3) = 11
x – 3 = 11 ∨ x – 3 = – 11
x = 11 + 3 ∨ x = – 11 + 3
x = 14 ∨ x = – 8
