3. A sculptor is planning to make two triangular prisms out of steel. The sculptor will use A ABC for the bases of one prism and A DEF for the bases of the other prism.
(a) Is A ABC similar to A DEF? Explain and show supporting calculations.
(b) Suppose the sculptor makes both prisms with the same height. Which prism will have a greater
volume? How many times greater? Show calculations to support your answer.

Set up and solve a proportion for the following application problem. if 55 pounds of grass seed cover 404 square feet, how many pounds are needed for 7272 square feet?

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
