ok, now the mode for city B
OpenStudy (anonymous):
17
OpenStudy (phi):
The difference between the mode number of automobile accidents per day for each city
which boils down to the difference in those modes 17-10
OpenStudy (anonymous):
7
OpenStudy (phi):
(this is more a reading test!)
ok
next
7 is how many times the mean absolute deviation?
they tell us mean absolute deviation for each city is 1.75.
so
7 is how many times 1.75 ?
7= 1.75 x
solve for x

1.75/7
OpenStudy (phi):
that looks upside down
if the question were
6 is how many times 2
you would do 6/2 and get 3. 6 is 3 times 2
OpenStudy (anonymous):
so what do u do now
OpenStudy (phi):
you are solve
1.75 x = 7
divide both sides by 1.75
