For the following problem, do not use algebra. Make a guess that satisfies one or more conditions of theproblem, and then evaluate your guess. You must show work to support your solution, for example, use a tableto document your guesses.There are 54 animals in a pen; all the animals are either ducks or piglets. If there are 122 feet on these animals(and none of them are missing legs), how many ducks are there in the pen? How many piglets?a) Use your own words to describe the big-picture ideas in the following scenario:b) Use your own words to list out each important detail in the scenario:c) Solve by Guess and Check:

The height, y, of the ball above the ground (in feet)is given as a function of time, t (in seconds) by.(A) Find the velocity of the ball at time t. What is the sign ofthe velocity? Why is this to be expected?(B) Show that the acceleration of the ball is a constant. What arethe value and sign of this constant?(C) When does the ball hit the ground, and how fast is it going atthat time? Give your answer in feet per second and in miles perhour (1ft/sec=15/22mph).

Suppose that x is the probability that a randomly selected person is left handed. The value (1-x) is the probability that the person is not left handed. In a sample of 1000 people, the function V(x)=1000x(1-x) represents the variance of the number of left-handed people in a group of 1000. What is the maximum variance?
