Consider this:
If a test gives a positive result for an infected person 98% of the time, that means that 2% of the time, it gives a negative result for an infected person, which would be a false negative.
Then,
if the test is 97& accurate (not precise) for non-infected people, that means that it gives a negative result 97& of the time. So a positive result will be given 3% of the time for non-infected people, which is considered a false positive.
Answer:
x = 11
Step-by-step explanation:
To make A║B, we need to assume it is.
Through alternate exterior angles theorem:
5x + 9 = 6x - 2
Solve algebraically for x:
5x + 9 = 6x - 2
9 = 6x - 5x - 2
9 = x - 2
9 + 2 = x
11 = x
x = 11
Solve for x:
(13 x - 5) (14 x - 36) = 0
Split into two equations:
13 x - 5 = 0 or 14 x - 36 = 0
Add 5 to both sides:
13 x = 5 or 14 x - 36 = 0
Divide both sides by 13:
x = 5/13 or 14 x - 36 = 0
Factor constant terms from the left hand side:
x = 5/13 or 2 (7 x - 18) = 0
Divide both sides by 2:
x = 5/13 or 7 x - 18 = 0
Add 18 to both sides:
x = 5/13 or 7 x = 18
Divide both sides by 7:
Answer: x = 5/13 or x = 18/7
