Answer:
LQ = 54
Median = 69
UQ = 94
Step-by-step explanation:
This list is already sorted for you, so you don't need to worry about that, otherwise you would need to sort the numbers in ascending order. To find the median, we do
, where n is the amount of numbers. This gives us 4, so the median is at position 4, so the median is 69. The lower quartile is simply
, so 2, so the lower quartile is 54. The upper quartile is
, so 6, so the upper quartile is 94.
You can add 9+1 then make ten and add 10 +1
Answer:
To get the slope (which we'll call n) of a line perpendicular to another line with slope (a/b), use

Then we just plug in the point we want to cross and solve for the constant.
Step-by-step explanation:
we see that m = 
so, 
now we have the equation

plugging in (6, -4) we get

This gives us our function

Answer:
c(x) = ($12) / x
Step-by-step explanation:
The general formula for inverse proportion is y = k/x.
In this specific problem, y represents the cost per person, k the dailyl cost ($12), and x the number of perople riding.
Then
c(x) = cost per person as a function of the number of people riding
= ($12) / x
Note that if only one person rides, that person pays $12/1, or $12; if two people, $12/2, or $6 per person, and so on.
