Len [333]

Answer:

The size of the sample after four hours is of 3158 bacteria.

Step-by-step explanation:

The population after t hours can be modeled by the continuous exponential growth model, which is:

$P(t) = P(0)e^{rt}$

In which P(0) is the initial population and r is the growth rate paremeter.

A growth rate parameter of 17% per hour.

This means that $r = 0.17$

Suppose also that a sample culture of 1600 is obtained from this population.

This means that $P(0) = 1600$

Find the size of the sample after four hours.

This is P(4).

$P(t) = P(0)e^{rt}$

$P(t) = 1600e^{0.17t}$

$P(4) = 1600e^{0.17*4}$

$P(4) = 3158.2$

Rounding to the nearest integer

The size of the sample after four hours is of 3158 bacteria.

Add all the chips to find the total amount.

7 + 9 + 3 + 6 = 25 chips

Since there are 6 blue chips (6/25), that's the probability of just getting once.

When you pick a blue chip and it doesn't get replaced, then that means there is one fewer blue chip and one fewer from the total amount.

5/24

Multiply both probabilities.

6/25 * 5/24 = 30/600

Simplify.

30/600 → 1/20

Therefore, the answer is B

Best of Luck!
