Effectiveness of New Drug To test the effectiveness of a new drug, a researcher gives one group of randomly

selected individuals the new drug and another group of

randomly selected individuals a placebo. The results of

the study are shown here. At a = 0.10, can the researcher

conclude that the drug results differ from those of the

placebo? Use the P-value method.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

wait this depends wether emily and zach how they are thinking.

yes they are the same.
