Question

question 23 of 25
which three scenarios most likely involve the use of an algorithm?
a. you set the temperature of your home using a digital thermostat.
b. you select the popcorn setting on the microwave and press the
\start\ button.
c. a streetlight comes on when its sensor detects that daylight is
fading.
d. you daydream about all the different places you want to travel to.

Explanation:

An algorithm is a set of steps to achieve a task.

• Option A: A digital thermostat uses an algorithm to regulate temperature (e.g., sensing, adjusting).
• Option B: The microwave popcorn setting follows a pre - defined algorithm (heating for specific time).
• Option C: The streetlight sensor uses an algorithm to detect light and turn on.
• Option D: Daydreaming is random, no algorithm. So A, B, C involve algorithms.

Answer:

A. You set the temperature of your home using a digital thermostat, B. You select the popcorn setting on the microwave and press the "Start" button, C. A streetlight comes on when its sensor detects that daylight is fading
