If the 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.
If the test is 97% accurate 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 a false positive.
(2p + 7)(3p-9)
2p x 3p= 6p^2
2p x -9= -18p
7 x 3p=21p
7 x -9=-63
6p^2 - 18p + 21p - 63
6p^2 + 3p -63 is the answer.

Answer:
1 3/4
Step-by-step explanation:
3 1/2 boxes of tomatoes currently. uses 1 3/4, taking it away basically.
3 1/2 - 1 3/4
3 2/4 - 1 3/4 ;; i did this with finding a common denominator for it to be easier for me to solve.
3 - 1 = 2
2/4 - 3/4 = -1/4
2 + -1/4 = 1 3/4
correct me if wrong.
