George has been selling 8,000 T-shirts per month for $9.50. When he increased the price to $10.50, he sold only 5,000 T-shirts.

Which of the following best approximates the price elasticity of demand?

-4.1538

-5.0769

-4.6154

-3.6923

Suppose George's marginal cost is $4 per shirt.

Before the price change, George's initial price markup over marginal cost was approximately ( 0.6368 OR 0.5211 OR 0.2895 OR 0.5789) . George's desired markup is   .

Since George's initial markup, or actual margin, was( LESS or GREATER) than his desired margin, raising the price was ( profitable or not profitable) .

1. A trial evaluated the fever-inducing effects of three substances. Study subjects were adults seen in an emergency room with diagnoses of the flu and body temperatures between 100.0 and 100.9ºF. The three treatments (aspirin, ibuprofen and acetaminophen) were assigned randomly to study subjects. Body temperatures were reevaluated 2 hours after administration of treatments. The below table lists the data.

C++ Design and implement a program (name it ComputeAreas) that defines four methods as follows: Method squareArea (double side) returns the area of a square. Method rectangleArea (double width, double length) returns the area of a rectangle. Method circleArea (double radius) returns the area of a circle. Method triangleArea (double base, double height) returns the area of a triangle. In the main method, test all methods with different input value read from the user. Document your code and properly label the input prompts and the outputs as shown below. Sample run: Square side: 5.1 Square area: 26.01 Rectangle width: 4.0 Rectangle length: 5.5 Rectangle area: 22.0 Circle radius: 2.5 Circle area: 19.625 Triangle base: 6.4 Triangle height: 3.6 Triangle area: 11.52
