Step-by-step explanation:
x+3y=12--(1)
x=-6y--(2)
put (2) in (1)
-6y+3y=12
-3y=12
divide both sides by -3
y=(12/-3)
y=-4
put y=-4 in (1)
x+3(-4)=12
x-12=12
x=12+12
x=24
Using it's concept, the probabilities are given as follows:
19. A. 1/3.
20. F. 1/6.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 1 + 1 + 3 + 4 + 3 = 12 papers. 4 have a score of 6, hence, in item 19, the probability is:
p = 4/12 = 1/3.
Which means that option A is correct.
2 papers have a score greater than 12, hence the probability in item 20 is given by:
p = 2/12 = 1/6.
Which means that option F is correct.
