Keats Library purchases a number of new books, all in the category of biography; the library does not acquire any other books. W
PtichkaEL [24]

Answer:

\large \boxed{87.5 \, \%}

Step-by-step explanation:

            Let x = the original number of books

Then 0.375x = the total number of biographies

 and 0.20  x = the original number of biographies

\text{Percent increase} = \dfrac{\text{ New number - Old number }}{\text{Old number }} \times 100\, \%\\\\= \dfrac{0.375x - 0.20x}{0.20x} \times 100\, \% = \dfrac{0.175x}{0.20x} \times 100\, \% = 0.875 \times 100\, \% = \mathbf{87.5 \, \%}\\\\\text{The number of biographies has increased by $\large \boxed{\mathbf{87.5 \, \%}}$}

Maya had $27. She spent all the money on buying 3 burgers for $x each and 2 sandwiches for $y each. If Maya had bought 2 burgers
SIZIF [17.4K]
Anything that is close to. 

Because $27- 3*$5 - 2*6 = 0 and $5*2 +1 *$6 = $16, $27-$16 = $11 left over. I can make a system of equations to prove that this is the correct answer.

the number of steps per day is said to be related to fitness level (as measured with vo2 testing). which type of validity is des
taurus [48]

The term "concurrent validity" refers to the relationship between step count with vo2 data.

<h3>Define the term concurrent validity?</h3>
  • The degree of agreement between two measurements or assessments made at the same time is displayed by concurrent validity.
  • It contrasts a brand-new test with one that has already undergone testing and been shown to be reliable.

You wish to evaluate a new survey that measures employee commitment's concurrent validity. In order to accomplish so, you may:

  1. Ask the same group of employees to respond to your new survey as well as an earlier (validated) survey. then contrast the outcomes.
  2. Obtain some staff responses to your new survey. The findings of a popular employee performance indicator, including a performance evaluation, should then be compared to the respondents' responses.

There is a connection between daily step count and fitness level (as collected with vo2 testing)

Thus, the term "concurrent validity" refers to the relationship between step count with vo2 data.
