A study of a new medication found that patients who took the medicine have reduced
blood pressure, compared to those who did not take the medicine. The research team
concluded that the medicine caused the reduction in blood pressure. Which study design
did they most likely use? (2 points)
They most likely used an experiment with patients randomly assigned to take the medicine or not
take the medicine
They most likely used an experiment with patients randomly assigned to groups based on their
blood pressure
They most likely used a survey asking patients if they took the medicine and how their blood
pressure was affected.
They most likely used a survey asking patients if they took the medicine and if they felt the
medication helped their blood pressure.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
