juin [17]

Complete question;

<em>The distribution of lengths of salmon from a certain river is approximately normal with a standard deviation of 3.5 inches. If 10 percent of salmon are longer than 30 inches, which of the following is closest to the mean of the distribution? 26 inches A 28 inches B 30 inches C 33 inches D 34 inches</em>

Option B is correct. The value that is closest to the mean of the distribution is 30inches.

The formula for calculating the z-score is expressed as:

z=\frac{ x-\mu}{\sigma}

Given the following parameters

\sigma = 3.5\\x = 26in

If 10 percent of salmon are longer than 30 inches, then:

  • P(x>30) = 0.1

Using the z table to get the value corresponding to the mean area 0.1.

  • The required z-score will be -1.285

Substitute the resulting parameters into the formula to get the mean of the distribution.

z=\frac{x-\mu}{\sigma}\\-1.285=\frac{26-\mu}{3.5}\\-1.285 \times 3.5 = 26 - \mu\\ -4.4975 = 26 - \mu\\\mu = 26 + 4.4975\\\mu = 30.4975\\\mu \approx 30in

Hence the value that is closest to the mean of the distribution is 30inches.

A nurse is caring for a client who is in the transition phase of labor and reports a pain level of 7 on a scale of 0 to 10. Whic
Nuetrik [128]

The action that the nurse who is caring for a client who is in the transition phase of labor should take is; C. Assist the client with patterned-paced breathing.

<h3>What is the duty of the Nurse?</h3>

The action that the nurse who is caring for a client who is in the transition phase of labor should take is; C. Assist the client with patterned-paced breathing.

The reason is that Patterned breathing refers to the act of breathing at any number of possible rates and depths. Some women prefer breathing deeply, using their diaphragm to fill their abdomen with air. Other women prefer light breathing, inhaling just enough to fill their chest. The goal is to find breathing patterns that have a calming and relaxing effect.

The benefits of patterned breathing are;

  • Breathing becomes an automatic response to pain
  • The mother remains in a more relaxed state and will respond more positively to the onset of pain
  • The steady rhythm of breathing is calming during labor
  • Provides a sense of well being and control
  • Increased oxygen provides more strength and energy for both the mother and baby
  • Brings purpose to each contraction, making contractions more productive

The missing options are;

A. Instruct the client to use effleurage

B. Apply counter pressure to the client sacral.

C. Assist the client with patterned-paced breathing.

D. Teach the client the technique of biofeedback

Ariana is accelerating her car at a rate of 4. 6 m/s2 for 10 seconds. Her starting velocity was 0 m/s. What was her final veloci
Studentka2010 [4]

Answer:

<h3>the answer is v=46 m/s</h3>

Explanation:

<h3>to find the final velocity we use formula from uniformly accelerated motion , equation 1, that is ; V=U+at</h3>

<h3>our given is U=0m/s</h3><h2> a=4.6m/s^2</h2><h3> t=10s</h3><h3>requaired,V=?</h3>

<h3>solution will be; V = u+at</h3>

<h3>replacing the values of each individual</h3>

<h3>V=0m/s+(4.6m/s^2)(10s)</h3><h3>V=0m/s+46m/s ;second found on the unit of acceleration canceled by the unit of time and finaly the left is m/s</h3><h3>V=46m/s</h3>
