$+4+4$

${e}^{x}=14$

$[{\mathrm{log}}_{a}{a}^{x}=x]$, $[{\mathrm{log}}_{e}x=\mathrm{ln}x]$

${\mathrm{log}}_{e}{e}^{x}={\mathrm{log}}_{e}14$

$x=\mathrm{ln}14$

$+4+4$

${e}^{x}=14$

$[{\mathrm{log}}_{a}{a}^{x}=x]$, $[{\mathrm{log}}_{e}x=\mathrm{ln}x]$

${\mathrm{log}}_{e}{e}^{x}={\mathrm{log}}_{e}14$

$x=\mathrm{ln}14$

A movie stuntman (mass 80.0kg) stands on a window ledge 5.0 mabove the floor. Grabbing a rope attached to a chandelier, heswings down to grapple with the movie's villian (mass 70.0 kg), whois standing directly under the chandelier.(assume that thestuntman's center of mass moves downward 5.0 m. He releasesthe rope just as he reaches the villian).

a) with what speed do the entwined foes start to slide acrossthe floor?

b) if the coefficient of kinetic friction of their bodies withthe floor is 0.250, how far do they slide?

Lowe's sells a very popular remote control operated ceiling fan, the Lantern Bay 54-in Matte Black LED Indoor/Outdoor Ceiling fan, with most of the sales being made in the summer months. Lowes makes a one-time purchase of these fans prior to each summer season at a cost of $40 each and sells each Lantern Bay fan for $200. Any fans unsold at the end of the summer season are marked down to $50 and sold in a special fall sale. By experience, all marked-down fans are sold. The following is the number of Lantern Bay fans sold during the last past 10 summers: $30,50,30,60,10,40,30,30,20,40.$

1. Estimate the mean and the variance of the demand for Lantern Bay fans each summer.

2. Assume that the demand for Lantern Bay fans each summer follow a normal distribution, with mean and variance given by your answer on 1). Determine the optimal number of fans for Lowes to buy prior to each summer season.
