The formula for Observed Score is; Observed score (X) = True score (T) + measurement error (e)

<h3>What is the observed score formula?</h3>

The formula for Observed Score is;

Observed score (X) = True score (T) + measurement error (e)

1) True score is the score that would be obtained if an individual took a test an infinite amount of times and those test scores were averaged. The concept of true score is theoretical because you can't give someone something an infinite number of times.

2) Standard error of measurement is the standard deviation of multiple test scores (how far the sample mean of the data is likely to be from the true population mean).

The less random error (e) in the measure, the more the observed score X approximates the true score T.

Thus;

Observed score = True Score + Error

If they work together. Mark, Naomi, and Yvonne can sort some
adoni [48]

Answer:

It will take Naomi 22 hours

Step-by-step explanation:

If they work together Mark, Naomi, and Yvonne take 11 hours, which means

three people represent 3* 11 = 33 man* hours

If they work alone Yvonne will take  5 man hours, and Mark will take 6* man hours.

Now we know that together they take 33 man hours therefore we have

5+ 6+ N = 33

Where N is Naomi's man* hours. We solve for N and get:

N = 33 - 11 = 22

N = 22

Naomi will take 22 hours to finish the job if she worked alone.

8-5(x+2)&lt;-5 what is the inequality with a line graph
Vadim26 [7]

The expression for the inequality is:

8-5(x+2)

We need to find which line represents this inequality. To do that we will use the left side of the inequality and rewrite it as a slope-intercept form. Which is done below:

\begin{gathered} y(x)=8-5(x+2) \\ y(x)=8-5x-10 \\ y(x)=-5x-2 \end{gathered}

The line for this inequality is "-5x -2". Where the slope is -5 and the y-intercept is -2. We can graph it as shown below:
