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)

A.) They most likely used an experiment with patients randomly assigned to take the medicine or not take
the medicine.

B.) They most likely used an experiment with patients randomly assigned to groups based on their blood
pressure.

C.) They most likely used a survey asking patients if they took the medicine and how their blood pressure
was affected.

D.) They most likely used a survey asking patients if they took the medicine and if they felt the medication
helped their blood pressure.

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

0,0

step-by-step explanation:

the given growth  function for the length of the fish (cm) is

f(m) = 5(1.07)m = 5.35m

where 

m = months

at the end of the study, the length is 9.19 cm. the  time for conducting the study is determined as

5.35m = 9.19

m = 1.7178 months

part a.

the study was performed over a time period  of about 1.72 months. therefore  the domain for  plotting the function is 0 < = m < = 1.72.

note:

if growth  continues at this rate for up to m months, then the domain would be 0< =m< =m.

part b.

the growth function is a linear function.

when m=0, f=0.

therefore the initial growth is zero, which represents the y-intercept.

part c.

assume that the growth function is valid for 0< =m< =9.

the average rate of change of the function is the slope of the linear function, which is 5.35 cm/month.
