Caught speeding suppose police set up radar surveillance on the stanford street described in exercise 18. they handed out a large number of tickets to speeders going a mean of 28 mph, with a standard deviation of 2.4 mph, a maximum of 33 mph, and an iqr of 3.2 mph. local law prescribes fines of $100, plus $10 per mile per hour over the 20 mph speed limit. for example, a driver convicted of going 25 mph would be fined 100 + 10152 = +150. find the mean, standard deviation, maximum, and iqr of all the potential fines.

The mean would be 100+10*(28-20)=$180

The max would be 100+10*(33-20)=$230

The IQR is $205-$135=$70

Using a graphing calculator, the standard deviation is $38.94.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
