Exhibit 8 of the case indicates that 97 rental requests arrived over a 26 week span. Assume that everyone rents a pair of skis for one weekend and that Salt Lake City has 4 pairs of rental skis. Also assume no variation in rental times (i. e. the standard deviation of rental times is zero) and that inter-arrival times are exponentially distributed (i. e. the coefficient of variation is 1). How long, on average, do customers have to wait for a pair of skis

hope this !

let me know

just took the test and my answers down below!

step-by-step explanation:

check the pic :

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
