Answer:
- probability of a false positive test result = 0.010
- The non-drug user will suffer from the result since it is positive
Step-by-step explanation:
The probability that the test result is a false positive
total number of cases studied (n) = 38 + 12 + 19 + 29 = 98
number of false positive cases ( x ) = 1
probability of false positive result = x / n = 1/98 = 0.010
The non-drug user will suffer from the result since it is positive
for number 7 is TQS and TSR
A.) Yes you can, the expression would be (2.95 x Y) + 4 = X
B.) (2.95 x 24) + 4 = $74.80
C.) (2.95 x 57) + 4 = X
2.95 x 57 = 168.15 + 4 = 172.15
so basically they can buy 57 books without going over $175
When you estimate, you round the numbers up or down. In this case, I'll round 4,377 down to 4,000, because 8 divides nicely into that number. 4,000/8 = 500.
You could estimate it to be about 500.
Hope that helped you.
(You can round your own numbers if you would like, but remember that rounding should make it easier for you to solve!)
