Question

Which two scenarios show how algorithms are used to improve people's

lives?
A. Traffic signals placed at freeway on-ramps are used to regulate
how often cars can enter a freeway.
B. Two friends have a conversation about schoolwork while eating
lunch together.
C. A person sings the words to the song that makes them happiest.
D. Waitstaff use an app to take reservations and seat customers at a
busy restaurant.

Answer 1

Algorithms are used to improve people's lives in scenarios such as traffic signals and restaurant reservations.

Step-by-step explanation:

Two scenarios in which algorithms are used to improve people's lives are:

1. Traffic Signals: Traffic signals placed at freeway on-ramps are used to regulate how often cars can enter a freeway. The timing of the signals is determined by algorithms that consider factors such as traffic flow, congestion, and safety. This helps to manage the traffic effectively and prevent accidents.
2. Restaurant Reservations: Waitstaff use an app to take reservations and seat customers at a busy restaurant. The app utilizes algorithms to optimize the seating arrangement, minimizing waiting times and ensuring efficient allocation of tables.
