Step-by-step explanation:
A placebo is a fake put into place in order to make a user believe something is happening when it is not. This is used often in medicine, where a doctor may tell a patient they are receiving treatment for some condition, but in fact they are getting nothing. Often times this can actually make a change for the patient due to simply believing they are getting treatment. The placebo effect is also used in Statistics, with 2 groups, one getting the treatment, and one simply receiving a placebo. This is helpful because it shows the effect of treatment or medication more accurately.
Answers + Step-by-step explanation :
a) the equation should be:
7(n + 5) = 91 since you first add 5 to n and then multiply it by 7. The answer is 91 so that is on the other side of the equal sign
b) we can solve our equation to find for n, the number jim thought of
7(n + 5) = 91
I will use the distributive property.
7n + 35 = 91
Subtract 35 on both sides
7n = 56
Now divide 7 on both sides to find n
n = 8
The number Jim was thinking of was 8! this should be correct, hope this helps!

Answer: Option C.
Step-by-step explanation:
You need to find the distance AB with the formula for calculate the distance between two points:
Then, substituting the coordinates of the points A(1,1) and B(4,1), you get:
You know that A'B'=6, then the scale factor of dilation can be calculated with:
Substituting values, you get:
This matches with the option C.
