The probability that the contestant wins at least one car is 3/5.

<h3>What is the probability?</h3>

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

For 1 car, we consider two possible outcomes:

P(1 car) = 2/6 x 4/5 + 4/6 x 2/5

P(1 car) = 8/15

For no car in either door

P(no car) = 4/6 x 3/5

P(no car) = 2/5

The probability that the contestant wins at least one car is the sum of the probability of one car and the probability of two cars:

P(2 cars) = 2/6 x 1/5

= 1/15

P(1 car) + P(2 cars) = 8/15 + 1/15

= 3/5

The population of a culture of cells grows according to the function P(t)= 90t/ t + 1, where t&gt; or =0 is measured in weeks. C
butalik [34]

Answer:

The average rate of change is \frac{18}{5}

Step-by-step explanation:

Given function that shows the population of a culture of cells,

P(t)=\frac{90t}{t+1}------(1)

Where, t represents the number of weeks.

Thus, the average rate of change in the population over the interval [0,24],

m=\frac{P(24)-P(0)}{24-0}

From equation (1),

=\frac{\frac{90\times 24}{24+1}-\frac{90\times 0}{0+1}}{24}

=\frac{\frac{2160}{25}-\frac{0+1}{0}}{24}

=\frac{2160}{25\times 24}

=\frac{2160}{600}

=\frac{18}{5}

A lake has a small population of a rare endangered fish. The lake currently has a population of 11 fish. The number of fish is i
balu736 [363]

5% of 11 is 0.55. What number times 0.55 = 11? Well if we divide 11 by 0.55, we see that the answer is 20. So, the population will double in 20 years. If the population is 22 in 20, it stands to reason that it will take another 20 years to double from 22 to 44. So, the population will reach 44 in 40 years.

Hope this helps.
