Answer:

9450000 red cars

Step-by-step explanation:

Out of 100 cars that passed, 27 of them where red.

The probability of red car to pass = 27/100

Probability of red car to pass = 0.27.

Now we are given a new value.

The value is 35 million cars.

Which is equal to 35000000.

We are asked to estimate the number of cars that will be red from Ben previous calculations.

The estimate = probability of red cars passing* number of cars in total

The estimate = 0.27 * 35000000

The estimate = 9450000

So we expect 9450000 red cars to pass

At the moment a certain medicine is injected, its concentration in the bloodstream is 120 milligrams per liter.
igomit [66]

Answer:

c(t) = 120 [0.7]^{t}

Step-by-step explanation:

At the moment a certain medicine is injected, its concentration in the bloodstream is 120 milligrams per liter.

From that moment forward, the medicine's concentration drops by 30% each hour.

Therefore, the medicine concentration c(t) in mg/liters after t hours will be modeled as

c(t) = c(0) [1 - \frac{30}{100}]^{t}

⇒ c(t) = c(0) [1 - 0.3]^{t} 

⇒c(t) = 120 [0.7]^{t} . (Answer)
