VashaNatasha [74]

Answer:

(A)

$P(X \geq 0.8) = \int\limits_{0.8}^{\infty} f(x) \, dx = \int\limits_{0.8}^{1} 1.25(1-x^4) \, dx = 0.08192$

(B)

Then the cumulative function would be

$CF(x) = 1.25x - 0.25x^5$ if 0<x<1

0 otherwise.

Step-by-step explanation:

(A)

We are looking for the probability that the random variable X is greater than 0.8.

$P(X \geq 0.8) = \int\limits_{0.8}^{\infty} f(x) \, dx = \int\limits_{0.8}^{1} 1.25(1-x^4) \, dx = 0.08192$

(B)

For any $x$ you are looking for the probability $P(X \geq x)$ which is

$P(X \geq x) = \int\limits_{-\infty}^{x} 1.25(1-t^4) dt = \int\limits_{0}^{x} 1.25(1-t^4) dt = 1.25x - 0.25x^2$

Then the cumulative function would be

$CF(x) = 1.25x - 0.25x^5$ if 0<x<1

0 otherwise.

In a hospital, 30% of the beds are vacant. There are 210 patients in beds at the hospital currently. How many beds are there at

ANTONII [103]

By using the concept and properties of percentages, we conclude that the hospital has a total of 300 beds.

<h3>How many beds are available in a hospital?</h3>

In accordance with the statement, there are 210 patients in the beds of a hospital and 30 % of the beds are available. We must take advantage of the concept of percentage to calculate the total number of beds. 210 patients occupy 70 % of the beds.

Then, the total number of beds at the hospital is determined by dividing the number of beds with patients and its respective percentage:

n = 210 / 70 %

n = 210 / (70 / 100)

n = (210 · 100) / 70

n = 300
