The town manager uses the median to show that the average amount of trash thrown away per person per week in each sample is the same. What is the town manager’s error?
The medians of the data sets are not the same.
He should have used the mean to determine the average because the data sets are approximately symmetric.
He should have used the IQR of the data sets to determine the average because the first data set has more large numbers than the second data set.
He should have used the MAD to determine the average because the data sets do not contain outliers.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

the two may have that, even a breakdown is probably offered

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
