Which statement best compares the spreads of the data sets? A. The interquartile range (IQR) for Democratic electoral votes, 68.5,
is less than the IQR for Republican votes, 117.5.
B. The range for Democratic electoral votes, 366, is greater than the
range for Republican votes, 185.5.
C. The interquartile range (IQR) for Democratic electoral votes, 186.5,
is very nearly equal to the IQR for Republican votes, 185.5.
D. The median for Democratic electoral votes, 299, is greater than the
median for Republican votes, 238.5.

i pretty sure it is

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.
