The number of accidents on a certain section of I-40 averages 4 accidents per weekday independent across weekdays. Assuming the

AysviL [449]

Answer:

1.83% probability there are no car accidents on that stretch on Monday

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given time interval.

The number of accidents on a certain section of I-40 averages 4 accidents per weekday independent across weekdays.

This means that $\mu = 4$

What is the probability there are no car accidents on that stretch on Monday?

This is P(X = 0).

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-4}*(4)^{0}}{(0)!} = 0.0183$

1.83% probability there are no car accidents on that stretch on Monday

A submarine dives to a depth of 54.6 meters below the surface of the water in 4 minutes. What integer represents the constant ra

Katen [24]

Just divide the depth he dove by the time it took him to dive.

54.6 / 4 = 13.65

So he traveled at a constant rate of 13.65 meters a minute.

I got number 7 wrong can someone help me with the answer and the work

Amiraneli [1.4K]

To figure out this problem break it down into steps.

We know that there are 1 - 25 or 25 cards in total, one card is taken out and not replaced so now there are only 24 cards.

25 - 1 = 24.

Find the probability of getting one number greater than 10, this would be all numbers from 10 - 25, which are 25 - 10 = 15 options to choose that will give you a value greater than 10.

Probability = 15/24 = 5/8.

For 2 cards simply multiply the probability by itself to get 2 cards where the number is greater than 10.

5/8 • 5/8 = 25/64.

The probability of getting 2 cards that are greater than 10, are 25/64.

This is the solution.
