A small drugstore orders copies of a certain magazine for it magazine rack each week. Let X=demand for the magazine, with pmf \begin{array}{|l|l|}\hline x&1&2&3&4&5&6\\\hline p(x)&\frac{1}{15}&\frac{2}{15}&\frac{3}{15}&\frac{4}{15}&\frac{5}{15}&\frac{6}{15}\\\hline\end{array} Suppose the store owner actually pays $1.00 for each copy of the magazine and the price to customers is$2.00. If magazines left at the end of the week have no salvage value, is it better to order three or four copies of the magazine?

A. If the shoes are discounted 25%, what percent of the original price is the original price?
25% discount is the same as □□% of the original price.
B. Fill in the boxes to set up the equation to find the original price of the shoes.
□□% ⋅⋅ Original Price −=61.25−=61.25

A wagon with two boxes of Gold, having total mass 300 kg, is cutloose from the hoses by an outlaw when the wagon is at rest 50m upa 6.0 degree slope. The outlaw plans to have the wagon roll downthe slope and across the level ground, and then fall into thecanyon where his confederates wait. But in a tree 40m from thecanyon edge wait the Lone Ranger (mass 75.0kg) and Tonto (mass60.0kg). They drop vertically into the wagon as it passes beneaththem. a) if they require 5.0 s to grab the gold and jump out, willthey make it before the wagon goes over the edge? b) When the twoheroes drop into the wagon, is the kinetic energy of the system ofthe heroes plus the wagon conserved? If not, does it increase ordecrease and by how much?

A) What is the diameter of the path followed by this alpha particle?
B) What effect does the magnetic field have on the speed of the particle?
C) What are the magnitude of the acceleration of the alpha particle while it is in the magnetic field?
