- A box contains only blue and black glass

SAT
1 answer:
Tomtit [17]3 years ago
3 0

Answer:

D.

Explanation:

Blue beads are 3 times more likely to be pulled. Therefore, since there are 12 beads in total the ratio which would fit the ratio of probability to pull blue beads compared to black beads would be 9/12 leaving 3/12 probability to pull a black bead. if you simplify the fractions you get 3/4 and 1/4 where 1/4 (the probability to pull a black bead) is three times less than the probability to pull a blue bead.

If you examine a rock sample and observe fossils in it, what type of rock does the sample represent?
PolarNik [594]
Sedimentary Rock
Here's Why:
Fossils also form from molds and casts. If an organism completely dissolves in sedimentary rock, it can leave an impression of its exterior in the rock, called an external mold.
I got this information from http://www.livescience.com/37781-how-do-fossils

kupik [55]

Answer:

The answer is based off of the second paragraph of the 2nd source:

One development that was vital to the principle of equality was the American and French revolutionaries not conforming to traditional ways of life. For example, the revolutionaries expanded the “whole horizon of age.” This allowed more people to conform to their own agendas and not be suffocated by the “royal charisma.”

Explanation:

I am pretty sure this will give you the general idea of one of the actions took by revolutionaries to allow some form of equality. I would suggest putting this general statement into your own words to avoid any issues just in case my answer isn't sufficient :)

The nurse is teaching a patient with asthma how to use a peak flowmeter. What does the nurse include when teaching this patient?
denis-greek [22]

When teaching a patient how to use a peak flowmeter, the nurse should include the following steps:

  • Stand or sit up straight and make sure the indicator is at the bottom of the scale.
  • Take a deep breath and fill the lungs completely.
  • Place the mouthpiece in the mouth and close the lips tightly around it. Do not put the tongue inside the mouthpiece.
  • Blow out as hard and fast as possible in a single breath.
  • Note the number on the scale where the indicator stops. This is the peak expiratory flow (PEF) rate.
  • Repeat the process two more times and record the highest of the three readings.

<h3>What is a peak flowmeter?</h3>

A peak flowmeter is a device that measures how well air moves out of the lungs. It can help a patient with asthma monitor their condition and adjust their medication accordingly.

There are some steps that need to be teached to the patient:

Stand or sit up straight and make sure the indicator is at the bottom of the scale.

Take a deep breath and fill the lungs completely.

Place the mouthpiece in the mouth and close the lips tightly around it. Do not put the tongue inside the mouthpiece.

Blow out as hard and fast as possible in a single breath.

Note the number on the scale where the indicator stops. This is the peak expiratory flow (PEF) rate.

Repeat the process two more times and record the highest of the three readings.

Once we get these readings, the next steps are:

Compare the reading with the personal best PEF rate and the asthma action plan. The personal best PEF rate is the highest reading obtained when the asthma is well controlled. The asthma action plan is a written guide that tells the patient what to do based on their PEF rate and symptoms.

If the PEF rate is in the green zone (80% or more of the personal best), the asthma is under control and the patient should continue with their usual medication.

If the PEF rate is in the yellow zone (50% to 79% of the personal best), the asthma is getting worse and the patient should follow the instructions for increasing their medication or seeking medical attention.

If the PEF rate is in the red zone (below 50% of the personal best), the asthma is severe and the patient should use their rescue inhaler and seek emergency care.

The nurse should also teach the patient how to clean and store the peak flowmeter, and when to replace it. The nurse should emphasize the importance of using the peak flowmeter regularly and keeping a record of the readings and symptoms. The nurse should also encourage the patient to share the results with their health care provider and to follow the asthma action plan.
