Answer:
By adding 1 to the quotient.
Step-by-step explanation:
The Harbormaster needs to arrange tripe for 37 cars
in one go ferry can carry a maximum of 8 cars
trips = 37/8 = 4.625 trips
Since the ferry can't go in decimals so we need one more trip to carry all the cars. Hence the best way to interpret the remainder of 37/8 is by adding 1 to the quotient which will make 5 trips.
12:7
12(2):7(2)
24:14
12:7 = 24:14

Set up an equation of ratios as shown below:
h 24 ft 4
----- = ---------- = ---
4 6 ft 1
Cross multiplying the 1st and 3rd fractions, we get h=16 ft (answer)
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.
