With a partner or a group, toss a number cube 30 times and record the number showing on each toss. Compare the histograms. Describe how the distribution of the mean changes as the number of tosses increases.

For each exercise, graph the ordered pairs in the same coordinate plane. (-3, -3), (0, -3), (-2, 4), (3, 0), (1, 4)

Start with the largest square you can construct from an 8$\frac{1}{2}$ in -by- 11 in. sheet of paper (you may want to make a few of them). Then do the following,
a. Construct a square with exactly one fourth the area of your original square. b. Construct a square with exactly one half the area of your original square.

[T] Consider a series combining geometric growth and arithmetic decrease. Let $a_{1}=1.$ Fix a > 1 and $0<b<a . \text { Set } a_{n+1}=a . a_{n}-b .$ Find a formula for $a_{n+1}$ in terms of $a^{n}, \quad a,$ and b and a relationship between a and b such that $a_n$ converges.

Why did conflict in Italy continue even after unification?

A pump is required to lift 800 kg of water (about 210 gallons) per minute from a well 14.0 m deep and eject it with a speed of 18.0 m/s. (a) How much work is done per minute in lifting the water? (b) How much work is done in giving the water the kinetic energy it has when ejected? (c) What must be the power output of the pump?

The volume of a gas is 5.80 L, measured at 1.00 atm. What is the pressure of the gas in mmHg if the volume is changed to 9.65 L? (The temperature remains constant.)
