In a study of helicopter usage and patient survival, among the 56,074 patients transported by helicopter, 235 of them

xxMikexx [17]

Using the hypergeometric distribution, it is found that the probability is 0.845 = 84.5%.

--------------------

The patients are chosen from the sample without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

The parameters are:

x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.

Combination formula:

is the number of different combinations of x objects from a set of n elements, given as:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

--------------------

56074 patients, thus $N = 56074$
Sample of 40, thus, $n = 40$
235 left against medical advice, thus, $k = 235$ .

The probability that none left against medical advice is P(X = 0), so:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 0) = h(0,56074,40,235) = \frac{C_{235,0}*C_{55839,40}}{C_{56074,40}} = 0.845$

The probability is 0.845 = 84.5%.

−8(2−3w)−5w Tell me the answer please. Thanks!

LenaWriter [7]

Firstly simplify both sides
using distributive terms
(-8)(2)+(-8)(-3w)+-5w
=-16+24w+-5w
combine like terms
-16+24w+-5w
=(24w+5w)+(-16)
=19w+-16
the answer is 19w+ -16

A passenger on a ferris wheel moves in a vertical circle at constant speed.

NeTakaya

Answer and Explanation :

The forces are balanced because an unbalanced force will cause the Ferris wheel to accelerate.

According to Newtons's first law of motion, a body will continue in its state of rest or uniform motion unless it is acted upon by an unbalanced force. According to the question, the Ferris wheel moves in a vertical circle at a constant speed.

Note that, the fact that the speed is constant implies that the forces are balanced because an unbalanced force will cause the Ferris wheel to accelerate.
