Discuss how economic growth is behind in less developed countries due to its land use.
If A and B are two non-mutually exclusive events, then
PrA∪PrB is
Select one:
a. PrA+PrB+PrA∩Pr(B)

8. A specific manufacturer makes each launch vehicle type, and a manufacturer can make
many different launch vehicle types.
9. Each launch carries one payload, and a payload is only carried by one launch.
10. A manufacturer also makes each payload, and a manufacturer can make many different
payloads over time.
11. Multiple crew members can be carried on a crewed launch, and each crew member can be
carried on multiple launches over time.
12. Each crew member has a nationality (the country they come from), and their name and
surname also need to be recorded.
13. Crew members can appear in the database before they launch for the first time.
Draw an Entity Relationship Diagram (ERD) using Unified Modelling Language (UML) notation, representing these business rules. Your design should be at the logical level – include surrogate primary key and foreign key fields and remember to remove any many-to-many relationships.
in about 200 words, discuss how economic growth is behind in less developed countries due to built environment and infrastructure.
4. A launch requires a launchpad that hosts it, a launch vehicle (the rocket), and the payload.
5. For a launch, the date, time and name should be recorded as well as whether it is a crewed
launch or not.
6. Each launch is performed by a launch vehicle. The serial number for the launch vehicle
should be recorded. A launch vehicle can perform multiple launches over time.
7. Each launch vehicle is of a specific launch vehicle type. The name, maximum thrust and
whether it is reusable need to be recorded for the launch vehicle type.
8. A specific manufacturer makes each launch vehicle type, and a manufacturer can make
many different launch vehicle types.
9. Each launch carries one payload, and a payload is only carried by one launch.

All the following are approaches to assigning probability to events except
Select one:
a. Empirical Approach
b. Subjective Approach
c. Classical Approach
d. Objective Approach
