False positives are positive results from the test of a non-infected person, which happens 100-97=3% of the time, choice C.
The answer i believe is 1
The equation that is given in the question is:
3 (3y - 12) = 0
9y - 36 = 0
9y = 36
y = 36/9
= 4
The value of y in the equation is 4. The correct option among all the options that are given in the question is the first option.
So, we have 2 canoes with teams. They are both at a constant speed of 6mph, but one of them is 2mi ahead.
Assuming
and
,we express that as:
Team A = 
Team B = 
Because of those 2 extra miles and both canoes travelling at the same constant speed, they will never reach one another, like you correctly answered below.
