Answer:
17550 solutions
Step-by-step explanation:
Given that:
y1 +y2+y3+y4=27
where;
(yi ≥ 0 and yi
)
The no. of a nonnegative integer determines the number of ways to choose 27 objects from (4) distinct objects with repetition regardless of the order.
i.e

∴
The number of nonnegative integer solution is 





= 17550 solutions

Correct option is C. The Amazon River carries more water than any other river in the world.
The Amazon River carries more water than any other river in the world. In fact, the Amazon River is responsible for about one-fifth (twenty percent) of the fresh water that flows into the world's oceans. The Amazon River is the second longest river in the world and is about 4,000 miles (6400 km) long.
The Amazon is considered the world's largest river by volume, but scientists have believed it is slightly shorter than Africa's Nile. The Brazilian scientists' 14-day expedition extended the Amazon's length by about 176 miles (284 kilometers), making it 65 miles (105 kilometers) longer than the Nile.

What you do is move the equation around so the 12 -4.5x would now turn into y=-4.5x+12
50 mg/kg/day x 34 kg = 1700 mg/day
1700 mg/day x 1 day/24 hrs x 4 hrs = 283 mg every 4 hrs
283 mg/4hrs x 1 tablet/400 mg = 0.7 tablets
So to acieve the desired dose, the pati should take seven tenths of a tablet every 4 hours. Thats an unusual dosage since it’s difficult to take 0.7 tablet. The question didnt ask about the liquid suspension so I didn’t include that.
