In examining Reconstruction from 1863 to 1877, what conclusions can be drawn? a. It revitalized the Southern economy, which overshadowed northern and western economies in the decades to come.
b. Ensured equal rights for African-Americans, which continued to increase after 1877.
c. It failed to protect the long-term political and civil rights of African Americans, but did have the significant effect of ending slavery, and ensuring black families could not be forcibly separated.
d. Did little to really change the white supremacy of southern society, which resulted in legal segregation within a few decades of the end of Reconstruction.
e. It was a total failure and left no blueprint for the future.
f. Offered new economic opportunities for some former slaves (teachers, industrial workers, acquiring land in the west, joining the military), but share cropping kept the majority of former slaves in a cycle of debt.
g. The United States had become a declining world power in regard to trade.
h. It necessitated a "Second Reconstruction" in the 1960s to fulfill the promises of civil rights for African Americans.

Imagine us is a startup that offers high definition 3d prenatal ultrasounds for high-end customers. the service process includes four activities that are conducted in the sequence described below. (the time required for each activity is shown in parentheses): activity 1: welcome a patient and explain the procedure. (20 minutes)activity 2: prep the patient (e.g., show them to the room, apply ultrasound gel). (17 minutes) (*your id number represents the amount of time needed to complete this task)activity 3: take images. (5 minutes)activity 4: discuss diagnostic with patient. (20 minutes)at each location there are employees (servers) s1, s2, and s3. the assignment of tasks to servers is the following: s1 does activities 1 and 2.s2 does activity 3.s3 does activity 4.a. what is the capacity of this process (in customers per hour)? b. suppose 3 patients arrive every hour on average. ignoring any “start of day” or “end of day” effects, what are the utilizations of all three servers (%)? c. suppose each activity can be done by any server and any server can do any set of activities. however, each activity is done by only one server. for example, a possible assignment includes: s1 does activity 1, s2 does activity 2, and s3 does activities 3 and 4. of course, the original assignment of servers to activities is also feasible. what is the maximum capacity of the process (in customers per hour)? d. now consider the capacity measures in (c) and (a), what is the percentage change? why can you improve capacity without using additional resources? (there is no free lunch, right? )note: for all hw assignments, show your process of getting the results. only providing the final answers is not acceptable and will get 0%. if necessary, use a separate sheet of paper to show your work.
