<u>Answer:</u>

Option E. The probability of someone not using steroids testing positive for steroids is \bold9.40000000000001\%\bold.

<u>Solution: </u>

The drug company advertises test for steroids is 92.1\%

It has a true negative effectiveness of 90.6\%

The probability of someone not using steroids testing positive for steroids is (100\% - 90.6\%) = 9.4\%

So the Answer is E. The probability of someone not using steroids testing positive for steroids is 9.40000000000001\%.

Gia got some books from Library yesterday she got five books today Gia returned three books Gia has six books how many books did
makvit [3.9K]

Answer: 4


Explanation:


You can write an algebraic expression to represent the sequence with the books in this way:

  • yesterday she got five books: 5
  • today returned three books: - 3
  • how many books did Gia have to begin: n
  • At the end she has six books, which means that you can set an equality:

       n + 5 - 3 = 6

Now you follow these steps to clear the unknown:

  • do the operations in the left side: n + 2 = 6
  • use subtraction property of equality: n = 6 - 2
  • do the operations: n = 4

And that is the number of books whith which Gina started: 4
