7 0

Answer:

When seeking to determine the number of shirts made by employees subjected to noise with and without the use of headphones, the dependent variable is the number of shirts made by the employee.

Explanation:

In a study or research, the dependent variable is the result of the intervention on the independent variable, which can be modified. In the case presented, the dependent variable is the quantity of shirts made by the employees, the number of which is measured at the end of the study.

It is expected that those employees who block the noise using headphones produce a greater number of shirts than those exposed totally or partially to noise.

For the other options:

  • <u><em>The amount of noise</em></u><em>. This can modified by the use or not of headphones and is the independent variable, subject to modification.</em>
  • <u><em>The type of music the employees listen to while they work</em></u><em>.  Does not represent dependent or independent variable.</em>
  • <u><em>The amount of training employees need</em></u><em>. It is not the variable being studied.</em>

A nurse is preparing a client for discharge following an abdominal hysterectomy for fibroids. After providing discharge teaching
lesantik [10]

Answer:

Answer is option B -  "I should shower rather than take a tub bath."

Explanation:

Abdominal hysterectomy is the surgical removal of a part or all of the uterus by making an incision in the lower abdomen. After the surgery, the patient normally spends 2 - 5 days in the hospital and takes at least 4 - 6 weeks to get completely better. Some of the major discharge instructions are;

  • Drink enough water and eat smaller meals that are rich in proteins and fiber and plenty of fruits and vegetables daily. This helps with the healing process and prevents constipation.
  • Avoid swimming or taking a tub bath, but can take showers.
  • Dressings over the incision should be removed daily and keep the wound area clean.
  • Avoid inserting anything such as tampons into the vagina for 6 weeks after the surgery.
  • Avoid all heavy activity including strenuous household activities, weightlifting, and other strenuous exercises. Short walking and light household chores can be done.
  • Avoid driving if the patient is taking narcotic pain-relieving medicines. Long trips in vehicles or airplanes are not recommended for 4 weeks after the surgery.

How do pioneer species make ecological succession possible on an island formed from a volcanic eruptions
SIZIF [17.4K]

Answer:

The correct option is <em>3. they break down rock into soil in which plants can grow</em>

Explanation:

When a disaster is such huge that even the soil and organic matter get removed from the place, then the succession that will occur in such kind of place will be termed as primary succession. For example, a volcanic eruption or an earthquake.

On the other hand, if after a disaster some of the organic matter remains on the land, then the succession that will occur will be termed as secondary succession. E.g a succession after fire

In primary succession, the pioneer species will be plants that require less soil such as the lichens. The lichens will break down the rocks into the soil and eventually new species of plants will start to grow on the land.

siniylev [52]

Answer:

rise over run

Explanation:

rise refers to the number of units going u or down a graph

run refers to the number of units going left or right

it is seen as so; \frac{rise}{run} , \frac{ delta y}{deltax} , or   \frac{y_{2}  - y_{1}}{x_{2} - x{1}}

Don't panic when I included "delta". Delta, it refers/means the small mathematical triangle found beside the rise and run symbols of y and x
