Security f has an expected return of 11.1 percent and a standard deviation of 44.1 percent per year. security g has an expected return of 16.1 percent and a standard deviation of 63.1 percent per year. a. what is the expected return on a portfolio composed of 29 percent of security f and 71 percent of security g? (do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e. g., 32.16.) b. if the correlation between the returns of security f and security g is .24, what is the standard deviation of the portfolio described in part (a)?

The business cycle is the periodic but irregular up-and-down movement in economic activity, measured by fluctuations in real gross domestic product (gdp) and other macroeconomic variables. a business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. economists note, however, that complete business cycles vary in length. the duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations. but the term "business cycle" is still primarily associated with larger (industry-wide, regional, national, or even international) business trends.
