A colony of an animal begins with one pair of mature animals, which will produce a pair of offspring (one male, onefemale) after two months. Assume that all animals mature in 2 months and produce a pair of offspring (one male, onefemale) after 4 months. If no animals ever die, how many pairs of mature animals are there after 14 months? (Hint: AFibonacci sequence models this colony.)The number of pairs of mature animals after 14 months is

Tyler and his cousin are playing a game where they pick up colored sticks. Tyler currently has 32 points and likes to pick up the red sticks, earning 8 points every turn. His cousin just lost all her points on the previous turn, and has a strategy to catch up by getting all the teal ones, earning 9 points per turn. In a certain number of turns, the score will be tied. How long will that take? How many points will they each have? In __ turns, both players will have __ points.

The Infinite Monkey Theorem states that a monkey hitting keys completely at random on a typewriter for an infinite amount of time will, eventually, type any given text. Even the complete works of William Shakespeare. Some quotes are truly amazing. Consider the famous quote by Gen George S. Patton: "WHEN IN DOUBT, ATTACK" That's 21 amazing characters. Suppose a monkey is seated in front of a KEYBOARD WITH 28 CHARACTERS (one for each of the 26 letters in the alphabet, plus the space bar, and a comma). Suppose the monkey types only 21 characters completely at random. If X is the number of different 21 character strings it could have typed, then the chances that it typed the quote is one divided by X. What is X?

Data were collected from a random sample of 330 home sales from a community in 2003. Let Price denote the selling price (in $1,000), BDR denote the number of bedrooms, Bath denote the number of bathrooms, Hsize denote the size of the house (in square feet), Lsize denote the lot size (in square feet), Age denote the age of the house (in years), and Poor denote a binary variable that is equal to 1 if the condition of the house is reported as "poor." An estimated regression yields Price=129.9 +0.529BDR+25.5Bath +0.170Hsize +0.004Lsize +0.098Age-53.2Poor, R² = 0.78, SER=45.2.

You are interested in finding out if kangaroo rats that have been offered food ad lib(unlimited food) for the previous 24 hours store a different amount of food in their pouches than kangaroo rats that have been starved for 24 hours. You take 8 kangaroo rats and starve them for 24 hours, then offer them food and count how many seeds are stored in their pouches in the next hour. You let your rats rest for one week, and repeat the experiment with the same rats, but offer them unlimited food for the 24 hours prior to the experiment. Run the appropriate statistical test. Rat ID # Seeds (starving) 3 Seeds (ad lib) 1 10 26 2 16 23 3 15 16 4 12 17 5 21 29 6 13 21 7 12 32 8 10 18
