6) Determine the total unit cell contents and the K+ (white circles) and Br (red or darker circles) coordination numbers and geometric arrangement of opposite charged ions around each of them in this rock salt crystal structure. 7) In the following XY2 cubic (fcc - X atoms) structure below, the blue Y atoms are in all tetrahedral holes. X = smaller red atoms and Y = larger blue atoms (a) What is the coordination number for the X (red atoms)? This is asking how many blue (Y) atoms are around each X and in what geometric arrangement? (b) Calculate the number of formula units that are the XY2 cubic unit cell.
Maylin runs a restaurant that sells two kinds of cookies. Maylin knows the restaurant must make at least 19 and at most 42 trays of the Chocolate Decadence. The restaurant must also make between 15 and 65 trays of the White Chocolate Blizzards. The trays of Chocolate Decadence take 13 ounces of flour, while trays of White Chocolate Blizzards require 14 ounces of flour. The restaurant only has 1274 ounces of flour available. If trays of Chocolate Decadence generate $1.61 in revenue, and trays of White Chocolate Blizzards generate $2.14, how many trays of the cookies should Maylin have the restaurant make to get the most revenue? Chocolate Decadence: White Chocolate Blizzards: Best revenue:

1. For each of the problems below find the recurrence relation and the two linearly independent solutions in term of $x - x_0$. (a) y'' - xy' - y = 0, \quad x_0 = 0. (b) y'' - xy' - y = 0, \quad x_0 = 1. (c) (1 - x)y'' + y = 0, \quad x_0 = 0.
pertain to this scenario. You are investigating two populations of hairy cantaloupes. One population has red fur, while the other population has white fur. Previous researchers showed that fur colour in hairy cantaloupes is controlled by a single gene with two alleles, one for red fur and one for white fur. You decided to cross two hairy cantaloupes with pink fur. What percentage of their offspring are expected to also have pink fur?
A key metric in the cell phone industry is average revenue per user (ARPU), which represents the average dollar amount that a customer spends per store visit. In 2011, AT&T reported their ARPU as $63.76. Suppose the standard deviation for this population is $22.50. What is the probability that the ARPU will be between $60 and $63 from a random sample of 38 customers?
