Assume that your friend is transferring from a community college to a four-year institution with a 3.8 GPA and 60 credit hours. During the first year at the new college, your friend takes 90 credits and earns a 3.3 GPA. Follow the process below to help your friend determine his overall GPA (combining the community college and four-year university credits). Show how you would use expected values to find your friend's combined GPA. Complete parts a) through c) below. Click the icon to view information about weighted GPAS. a) What percentage of the total credit hours was earned at the community college? 40% (Round to the nearest whole percentage point as needed.) b) What percentage of the total credit hours was earned at the four-year institution? 60% (Round to the nearest whole percentage point as needed.) c) Multiply the decimal equivalent for the percentages times the respective GPAS and add them together to get the combined GPA. 3.5 (Round to the nearest tenth as needed.)
