Answer:

0.2835 = 28.35% probability that an average person makes at least one MONTHLY visit to doctors' office and hospitals

Step-by-step explanation:

Mean during a time period means that we use the Poisson distribution.

Poisson distribution:

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.

It is estimated that an average person makes four visits a year to doctors' offices and hospitals.

A year has 12 months, which means that the monthly mean is $\mu = \frac{4}{12} = \frac{1}{3}$

What is the probability that an average person makes at least one MONTHLY visit to doctors' office and hospitals?

This is:

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

In which

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

$P(X = 0) = \frac{e^{-(\frac{1}{3})}*(\frac{1}{3})^{0}}{(0)!} = 0.7165$

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.7165 = 0.2835$

0.2835 = 28.35% probability that an average person makes at least one MONTHLY visit to doctors' office and hospitals

Solve 4x- c = k for x. <br>A. x = k-c/4<br>B. x = 4(k-c)<br>C. x- k+c/4<br>D. x = 4 (k+c)

Harrizon [31]

Answer:

A

Step-by-step explanation:

You would first add c to the side that k is on and then divide k+c by 4 because it is 4x which means they are being multiplied together so you have to divide to get them apart.
