5(x + 3) = x + 15....distribute
5x + 15 = x + 15...subtract x from both sides, subtract 15 from both sides
5x - x = 15 - 15
4x = 0
x = 0 <=

Officials at a major university wanted to know what percent of their students recycle paper. They conducted a random survey and
Crazy boy [7]

Answer:

0.95 = 95% probability that a randomly selected student at this university recycles at least some of the time

Step-by-step explanation:

For a randomly selected student, we have these following probabilities:

0.55 probability that they always recicle.

0.25 probability that they usually recicle.

0.15 probability that they recicle only when it's convenient.

0.05 probability that they never recicle.

What is the probability that a randomly selected student at this university recycles at least some of the time?

Always, usually or only when it's convenient.

0.55 + 0.25 + 0.15 = 0.95

0.95 = 95% probability that a randomly selected student at this university recycles at least some of the time

Assume that the Poisson distribution applies to the number of births at a particular hospital during a randomly selected day. As
kakasveta [241]

Answer:

0.9999985  = 99.99985% probability that in a day, there will be at least 1 birth.

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 interval.

Assume that the mean number of births per day at this hospital is 13.4224.

This means that \mu = 13.4224

Find the probability that in a day, there will be at least 1 birth.

This is:

P(X \geq 1) = 1 - P(X = 0)

In which

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

P(X = 0) = \frac{e^{-13.4224}*13.4224^{0}}{(0)!} = 0.0000015

Then

P(X \geq 1) = 1 - P(X = 0) = 1 - 0.0000015 = 0.9999985&#10;

0.9999985  = 99.99985% probability that in a day, there will be at least 1 birth.
