Which statements regarding multiple referral are true

Len [333]

The statements regarding multiple referrals that are true are:

Multiple referrals increase the power of the leadership.
Multiple referrals is more common in the U.S. House than the U.S. Senate.
Complex bills that concern many different issues may be assigned to different standing committees.

<h3>What is Multiple Referral?</h3>

This refers to the process where a proposed bill in the legislature is sent for a second reading.

Hence, we can see that in the United States legislature, multiple referrals help to increase the power base of the leadership and are more common in the U.S. House than in the U.S. Senate.

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%.

If we wanted to explore the idea that mother's smoking might explain the variation in birth weight, what visualization might be

Mila [183]

Answer:

If a mother is smoking and there are significant birth weights, a bar graph will be most effective. A bar graph can show how many children have similar weights, and you can tell which weights are most common.

Hope this helped.

. A motor is spinning a circular disk with a diameter of 2.5 inches at a rate of 7200 RPM (revolutions per minute). If the motor

Over [174]

The angle turned is obtained as 3.77 rads.

<h3>What is the angle of rotation?</h3>

We have the following information about the disk;

velocity 1= 7200 RPM

velocity 2 = 0 RPM

time taken = 0.01 seconds

We must convert from RPM to rad/s using the relation;

2π·7200/60 = 754 rad/s

Using;

θ = ωavt

θ = (754 rad/s + 0 rad/s)/2 * 0.01 seconds

θ = 3.77 rads
