1. Find the volume of the solid lying under the elliptic paraboloid x2/4 + y2/9 + Z = 1 and above the rectangle R = [-1, 1] times [-2, 2].
2. a. Sketch the region of the integration and change the order of integration of 0∫1 3y∫3 ex^2 dx dy.
b. Evaluate the integral 0∫1 3y∫3 ex^2 dx dy by evaluating the integral in (a) in which the order of integration has been reversed
3. Evaluate the integral ∫D √16 - x2 -y2 dA by changing to polar cooridination, where D is the region that lies between the circles x2 + y2 = 16. [Note the integral represents the volume of the solid that is inside the sphere x2 + y2 + z2 = 16 and outside the cylinder x2 + y2 = 4]
A bookstore has an annual demand for 40,000 copies of a best-selling book. It costs $0.90 to store one copy for one year, and it costs $15 to place an order. Find the optimum number of copies per order.

A sphere of fixed radius R is enclosed in a cone of height h and radius r. Express the volume V of the cone as a function of the slant angle of the cone.
A square's side is increased by 3 yards, which corresponds to an increase in the area by 81 square yards. How many yards is the side of the initial square?
A poll of 64 students found that 30% were in favor of raising tution to build a new math building. The standard deviation of this poll is 5%. What would be the standard deviation if the sample size were increased from 64 to 190?
Assume that the weight loss for the first month of a diet program varies between 6 pounds and 12 ponds, and is spread evenly over the range of possibilities, so that there is a uniform distribution. Find the probability of the given range of pound..
