Answer:

Face validity

Step-by-step explanation:

In quantitative research in mathematics, we have four major types of validity namely;

- Content Validity

- Construct validity

- Criterion validity

- Face validity.

Now;

> Construct validity seeks to find out if the tool used in measurement is a true representation of what is really going to be measured.

> Content Validity seeks to find out whether a test covers every part of a particular subject being tested.

> Face validity seeks to find out how true a test is by looking at it on the surface.

> Criterion validity seeks to find out the relationship of a particular test to that of another test.

Now, in this question, we are told that The survey seems like a good representation of measuring dietary habits after just asking questions about each meal and snack they consumed for the week. Thus, it is a face validity because it just appears true on the surface to be a good representation but we don't know if it is effective until we go deep like content validity

If an injectable solution contains 25μg of a dug substance in each 0.5 mL, how many milliliters would be required to provide a p
Kay [80]

Answer:

5mL would be required to provide a patient with 0.25 mg of the drug substance.

Step-by-step explanation:

The problem states that an injectable solution contains 25μg of a dug substance in each 0.5 mL, and asks how many milliliters would be required to provide a patient with 0.25 mg of the drug substance.

So, the first step is the conversion of 25ug to mg, since the problem asks the answer in mg.

Each mg has 1000ug. So

1mg - 1000ug

xmg - 25ug

1000x = 25

x = \frac{25}{1000}

x = 0.025 mg

It means that each 0.5mL of the solution contains 0.025mg of the drug. How many milliliters would be required to provide a patient with 0.25 mg of the drug substance.

0.5mL - 0.025mg

xmL - 0.25mg

0.025x = 0.5*0.25

x = \frac{0.5*0.25}{0.025}

x = 10*0.5

x = 5mL

5mL would be required to provide a patient with 0.25 mg of the drug substance.

6 – 3(2x – 4) = 2(1 + x)
ratelena [41]
     6 - 3(2x - 4) = 2(1 + x)
6 - 3(2x) + 3(4) = 2(1) + 2(x)
     6 - 6x + 12 = 2 + 2x
     6 + 12 - 6x = 2 + 2x
           18 - 6x = 2 + 2x
            <u>   + 6x       + 6x</u>
                  18 = 2 + 8x
                 <u>- 2  - 2         </u>
                  <u>16</u> = <u>8x</u>
                   8      8
                    2 = x
The answer is D.
