researchers recruited over 1{,}0001,0001, comma, 000 patients with chronic back pain to participate in a study about the benefits of acupuncture. each subject was randomly assigned to one of these treatment plans: traditional chinese acupuncture, placebo acupuncture, and conventional pain treatment (medication and physical therapy). what is the primary purpose of randomly assigning subjects to the different treatment plans?
Accupunture is best these days for medication and health therapy.
What is accupunture.?Acupuncture is a traditional medical practice in which a doctor inserts needles into certain body parts of a patient. The earliest documents date back at least 2,500 years. [1] "Acupuncture points" are locations on the body where tiny metal needles are inserted. It is a type of complementary medicine[2], and it is fundamental to Traditional Chinese medicine[3] (TCM). [4] It makes use of the yin and yang principle.It is debatable and has yielded conflicting findings to research acupuncture using the concepts of "evidence-based medicine" (science research). [9] Although the majority of research indicates that acupuncture's effects are primarily attributable to placebo, certain studies indicate that acupuncture can reduce pain. [10] There is evidence that any advantages of acupuncture are transient. [11] When compared to conventional medical therapies, there is inadequate evidence to justify the use of acupuncture. [12] In the long run, acupuncture is not more effective than conventional medicine. [13]Learn more about accupunture click here:

Answer:
x < -9
Step-by-step explanation:
2x + 4 < -14
Solve for "x"
Subtract 4 from both sides
2x + 4 < -14
2x + 4 - 4 < -14 - 4
Simplify
Subtract all the numbers
2x + 4 - 4 < -14 - 4
2x < -14 - 4
2x < -18
Divide both sides by the same factor
2x < -18
[tex]\frac{2x}{2}[/tex] < [tex]\frac{-18}{2}[/tex]
Simplify
Cancel the terms that are in both numerator and denominator
[tex]\frac{2x}{2}[/tex] < [tex]\frac{-18}{2}[/tex]
x < [tex]\frac{-18}{2}[/tex]
Divide
[tex]x < \frac{-18}{2}\\ x < -9[/tex]
The answer is [tex]x < -9[/tex]

is y=10.5x-5 proportional
The equation y = 10.5x - 5 is proportional
Given,
y = 10.5x - 5
We have to find this equation is proportional or not.
In mathematics, proportional relationships exist when two variables consistently change by the same multiple. The formula y = kx, where k is a constant multiplier that depicts the relationship between x and y, is used to represent proportional relationships. The line on the graph is always straight and goes through (0,0).
Here,
y = 10.5x - 5
10.5 is the constant multiplier that depicts the relationship between x and y.

Answer:
sum= 1080
Step-by-step explanation:
Answer:
The sum of an octagon is always 1080 degrees. The interior angles are usually all equal to 135 degrees, but this is an irregular octagon, making that not the case. Because the angles are not all equal, that does not mean that the octagon's sum is any different. Thus, the sum of the interior angles is 1080 degrees.

qiang drives 15 miles at an average speed of 30 miles per hour. how many additional miles will he have to drive at 55 miles per hour to average 50 miles per hour for the entire trip?
110 additional miles he will have to drive .
To calculate : additional miles qiang will have to drive
Let the additional no. of miles he has to drive be x .
⇒ Total Distance = 15 + x
Total Time ( in hrs ) = ( 15 / 30 ) + ( x / 55 ) = ( 1 / 2 ) + ( x / 55 )
The equation becomes ,
[ ( 15 + x ) ] / [ ( 1 / 2 ) + ( x / 55 ) ] = 50
On simplification we get ,
15 + x = 25 + ( 10x / 11 )
x = 110
Therefore , 110 additional miles he will have to drive .

it is given that I = PRT/100

Here we go ~
Let's express P (principle) in terms of I, R and T
[tex]\qquad \sf \dashrightarrow \: I= \dfrac{PRT}{100} [/tex]
[tex]\qquad \sf \dashrightarrow \: PRT = I \sdot 100[/tex]
[tex]\qquad \sf \dashrightarrow \: P = \dfrac{I \sdot 100}{RT} [/tex]
and that's it ~
P can be expressed in terms of I, R, T as P=100×I / (R×T)
Given equation
I=PRT/100
100 × I = PRT
100 × I / RT = P
P = 100 × I / RT
This formula is used to calculate Simple Interest, where P= Principal, I= Intrest to be Calculated. R= Annual rate of interest, T= Time (in years). Here one will shift the 100 from the denominator and multiply with the I next we will move the rate and time from the numerator to the denominator. The equation we now get will be in terms of I, R, and T and one can find the Principal using this equation.

find three consecutive integers such that 3 times the smallest is 18 more than the largest
The value of the three consecutive integers will be 10, 11, and 12.
What is Algebra?
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Three consecutive integers are such that three times the smallest is 18 more than the largest.
Let the three consecutive number be x, x + 1, and x + 2. Then the equation will be:
3x = (x + 2) + 18
Simplify the equation, then the value of the variable x will be:
3x = x + 2 + 182x = 20x = 20 / 2x = 10
Then the value of the integers will be:
x + 1 = 10 + 1 = 11x + 2 = 10 + 2 = 12
The value of the three consecutive integers will be 10, 11, and 12

find the volume of the frustum by calculating the radius
The value of 'r' is 15 cm. Then the volume of the frustum will be 2625 cm³.
What is the volume?Volume is a measurement of three-dimensional space that is utilized. It is frequently mathematically quantified using SI-derived units or different imperial or US traditional units. The concept of length is linked to the notion of capacity.
By the similar triangle, then the value of r is calculated as,
r/30 = 20/40
r = 15 cm
Then the volume of the frustum is calculated as,
V = 1/3 × (30/2)² × 40 - 1/3 × (15/2)² × 20
V = 1/3 × [9000 - 1125]
V = 1/3 × 7875

→ a² = 169 - 144
→ a = √25
→ [ a = 5 cm ]

Jodie aimed to beat Mandy's 74.6-second mark on the obstacle course. She had already spent 10.56 seconds on the ropes and fifty-and-a-fourth seconds ascending the wall. To match the record, we must determine how much time she had remaining.
Jodie's total time for climbing the wall is fifty and one fourth seconds=50.25 seconds
The total time on ropes is 10.56 seconds
The total time she spent is 50.25+10.56=60.81
Left time = Record Time-Spent time
