Given 5 blue marbles, 3 red marbles and 2 white marbles. Find the probability of choosing a red marble given that its not white

Maslowich

Answer:

The chances you will get a red marble over a white or blue marble is 30%

Step-by-step explanation:

If you add 5 + 3 + 2 you will get 10

You then turn it into a fraction

3/10 is the chance you will get a red over a blue or white, now we need to convert it into a percentage by turning to 10 into 100 and multiplying 3 x 10

Once you have done that you should have 30/100

Take the 100 away and turn it into a percentage

The answer would be 30%

Population Growth

ohaa [14]

Answer:

Step-by-step explanation:

Given that the number of a certain type of bacteria increases continuously at a rate proportional to the number present.

Initial population = 150

Hence equation for population P would be

$P(t) = 150e^{kt}$ where t = time in hours

When t=5, P = 450

Substitute to get

$3 = e^{5k}$

k=0.2197

$P(t) = 150e^{0.2197t}$ is P(t)

P will double when

$300 = 150e^{0.2197t}$

t =3.155

Between 3rd and 4th it would double

c) Yes it doubles when 3.155 hours lapsed from the start time since t in the equation is time lapsed from start time.
