Answer:

  True

Step-by-step explanation:

That is the conventional explanation for the "placebo effect." True

__

<em>Additional comment</em>

It is likely there is more to it than that. There is pretty good evidence that experimenter expectations, and the expectations of others, play a role, too.

Answer:
true

Explanation:

The placebo effect is when an improvement of symptoms is observed, despite using a nonactive treatment. It's believed to occur due to psychological factors like expectations or classical conditioning.

If x = 4, you would replace the “x”s with 4’s! So the problem would work out to be 4^2 - 4 over 4 - 8. 4^2 = 16. You would then subtract. 16 - 4 = 12. Now your problem is 12 over 4 - 8. 4 - 8 = -4. Now your problem is 12 over -4. So now you just divide. 12 / -4 = -3! -3 should be your answer! If you need me to write it out to show you I’d be happy to! Hope this helps! :)

What is the value of x in the equation 8x – 2y = 48, when y = 4?
Phoenix [80]
Hey there!

So, if y=(4), this would mean that we would do (2 \ * \ 4) and from this, we would get 8. 

We will then need to find what is (x).

(x) = 7

8*7 = \boxed{56}

So, the equation would really look like . . .

\left[\begin{array}{ccc} 8*(7)-2*4 = 48 \\ \\ x=\boxed{7}\end{array}\right]

Hope this helps.

A particle moves along a straight line. The distance of the particle from the origin at time t is modeled by the equation below.
laiz [17]

Answer:

The value of t that will satisfy the equation is π/6 (which is 30 degrees)

Step-by-step explanation:

The function that models the movement of the particle is given as;

S(t) = 2 sin(t) + 3 cos (t)

Now we want to the value of t between 0 and pi/2 that satisfies the equation;

s(t) = (2+ 3√3)/2 = 1 + 3√3/2

What we do here is simply find that value of t that would ensure that;

2sin(t) + 3cos(t) = 1 + 3√3/2

Without any need for rigorous calculations, this value of t can be gotten by inspection.

From our regular trigonometry, we know that the sin of angle 30 is 1/2 and its cos value is √3/2

We can make a substitution for it in this equation.

We obtain the following;

2 sin(30) + 3cos (30) and that is exactly equal to 1 + 3√3/2

Do not forget however that we have a range. And the range in question is between 0 and π/2

Kindly that π/2 in degrees is 90 degrees

So our range of values here is between 0 and 90 degrees.

So to follow the notation in the question, the value within the range that will satisfy the equation is π/6

Jackie’s test scores for the first semester are listed below.
jek_recluse [69]

Answer:

The answer is 91

Step-by-step explanation:

90 x 6 = 540

The numbers need to equal 540 all together to make an average of 90.

97 + 86 + 83 + 95 + 88 = 449

540 - 449 = 91

To check:

97 + 86 + 83 + 95 + 88 + 91 = 540

Therefore, the answer is 91
