summary of results from the Medical Outcomes Study

<h3>What is mental component summary (MCS)?</h3>

By reducing the number of statistical comparisons and, consequently, the influence of chance, physical component summary (PCS) and mental component summary (MCS) measurements enable the testing of health outcome hypotheses. Results from 16 tests involving patients (N = 1,440) who took part in the Medical Outcomes Study were analyzed in order to see how effective they were in comparison to a profile of eight scores. Age, diagnosis, disease severity, concomitant disorders, acute symptoms, self-reported changes in health, and recovery from clinical depression were all factors that were compared between groups that were known to differ at one point in time or change over time. By contrasting the statistical outcomes for each measure with those for the best scales in the same tests, the relative validity (RV) of each measure was calculated. variations

4x + 27 = -33 - x please help
Rudik [331]

Answer: x=-12

Step 1: Simplify both sides of the equation.

4x+27=−33−x

4x+27=−33+−x

4x+27=−x−33

Step 2: Add x to both sides.

x+27+x=−x−33+x

5x+27=−33

Step 3: Subtract 27 from both sides.

5x+27−27=−33−27

5x=−60

Step 4: Divide both sides by 5.

x=−12

Find the product mentally. [(x + 1)(x - 1)]^2 pls help. Be quick if you can =)
BartSMP [9]

Answer:

x^{4} -2 x^{2} +1

Step-by-step explanation:

<u>Step 1</u>:-

Given problem is [(x + 1)(x - 1)]^2

by using formula in side square bracket is

(a+b)(a-b)=(a^{2}-b^{2})

[x^{2} -1]^{2}

<u>Step 2</u>:- again we will use formula

(a-b)^{2} = a^{2} -2 a b+b^{2}

[tex](x^2-1)^{2} = (x^{2}) ^{2} -2 x^{2}  (1)+1^{2}[/tex]

on simplification we get

x^{4}-2 x^{2}  +1

<u>Final answer:-</u>

x^{4}-2 x^{2}  +1

WILL GIVE BRAINLIEST! Determine the coordinates of the point on the straight line y=3x+1 that is equidistant from the origin and
Lesechka [4]

Answer:

Step-by-step explanation:

The distance between a point (x,y) and the point (-3,4) is

d1= \sqrt{ (x+3)2+(y-4)2} .

The distance between a point (x,y) and the point (0,0) is

d2= \sqrt{x2+y2} .

You know what y is from the equation of the line, so substitute that, set d1=d2, and solve for x.

!!!!!!!HELP!!!!!!MEH!!!!!PLZ!!!!!!
Maru [420]

Answer:

The correct answers are

Sal walks 14 km in 4 h

Sal walks 3.5 km in 1 h

Step-by-step explanation:

Given:

Distance represented by Y axis in kilometer.

Time represented by X axis in hour,

The graph of line is showing distance walked. And the two points are (1, 3.5) and (4, 14).

In plotting of points the first coordinate is always the X coordinate that is time in hour here, and the second coordinate is always the Y coordinate that is distance in km.

Therefore, the given below two options are correct

Sal walks 14 km in 4 h

Sal walks 3.5 km in 1 h
