B ) 75 Miles per hour
75 + 64(10) = 640 + 75 = 715
715 ÷ 11 ( how many drivers ) = 65
12,007,000 || 210,700,000 || 1,210,707,000
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.

Answer:
<h2><u><em>
2-x</em></u></h2>
Step-by-step explanation:
(14 - 7x)/7 =
[7(2-x)]/7 =
2-x
by solving the first equation you'll get x= -24/13
if you solve the second option (B) then you'll the same result i.e x=-24/13
so option C is correct
