Alan is conducting an experiment to determine whether a new medication is effective in reducing coughing. he finds 2,000 volunteers with coughing issues and divides them into two groups. the
control group does not receive any medication; the treatment group receives the medication. the patients in the treatment group show reduced signs of coughing. what can alan conclude from this
experiment?

the answer is d. 75%

answer: are you

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

ummm seems that u didnt post the attachement !
