question 13 (4 points)
which of these strategies do engineers use to develop solutions to a problem?
a assume the outcome will be the same after each test
b conduct only one test
c design new models
d use different measurements in results

question 14 (4 points)
which type of technology would be best suited for studying and exploring the surface of the planets and moons in our solar system?
a rover
b satellite
c space - based telescope
d drones

question 15 (4 points)
what strategies do commercial airlines use to maximize profit? select three correct answers.
a provide flights to all major cities.
b add more seats on airplanes.
c negotiate for better prices on fuel and equipment.
d use smaller airplanes on less popular routes.
e lease passenger aircraft to the military for secret missions.

Explanation:

• Question 13: Engineers design new models to improve and develop solutions. Assuming the same outcome after each test is incorrect as tests often lead to changes. Conducting only one test is insufficient for development. Using different measurements in results is not a primary development - strategy.
• Question 14: Rovers are designed to move on the surface of planets and moons to study them. Satellites orbit and may not directly explore the surface in - depth. Space - based telescopes observe from a distance and drones are not typically used for planetary surface exploration in our solar system.
• Question 15: Providing flights to major cities increases customer base. Adding more seats on airplanes increases revenue per flight. Negotiating better prices on fuel and equipment reduces costs. Using smaller airplanes on less popular routes reduces unnecessary capacity costs. Leasing to the military for secret missions is not a common profit - maximizing strategy for commercial airlines.

Answer:

Question 13: C. Design new models
Question 14: A. Rover
Question 15: A. Provide flights to all major cities, B. Add more seats on airplanes, C. Negotiate for better prices on fuel and equipment, D. Use smaller airplanes on less popular routes
